    January 15, 2021
    BARRON, Circuit Judge.            This appeal arises out of a suit
    for damages that Chimene Mbague Nandjou brought against three
    defendants in connection with the April 2016 drowning deaths of
    her husband, William, and two-year-old son, Menelik, in a hotel
    pool   in   Montreal,       Canada.           The     defendants       are   Marriott
    International,      Inc.;     Marriott         Worldwide        Corporation;      and
    Reluxicorp, Inc., the Marriott franchisee in Montreal where the
    drowning occurred.
    Nandjou's suit was removed from the local Massachusetts
    court in which she had filed it to the United States District Court
    for the District of Massachusetts, and the District Court, after
    finding personal jurisdiction over the three defendants, then
    dismissed it based on the doctrine of forum non conveniens after
    determining that an adequate alternative forum for the claims was
    available in Canada.        Nandjou now appeals that ruling.
    The defendants contend that dismissal on that basis was
    proper and, alternatively, that the order of dismissal must be
    affirmed    on    the   ground    that    there       is    a   lack    of   personal
    jurisdiction over them.       We reverse the District Court's dismissal
    of Nandjou's claims based on forum non conveniens but affirm its
    ruling finding personal jurisdiction over the three defendants.
    I.
    The   following      facts,       which    we   draw   from      Nandjou's
    complaint and the limited discovery that was allowed, are not in
    - 3 -
    dispute.   At the time of the events that gave rise to this suit,
    Nandjou, her husband, and their three children lived in Lynn,
    Massachusetts.   At that residence, they received numerous direct
    mailings from the Marriott defendants advertising various Marriott
    properties.   On at least three occasions, Marriott sent materials
    to Nandjou and her husband's address that promoted "The Residence
    Inn by Marriott" in Montreal.    In the spring of 2016, after having
    viewed those mailings, which included photographic depictions of
    the hotel and described its pool, Nandjou's husband booked a stay
    there.
    On that trip, on April 20, 2016, Nandjou's husband took
    the three children to the hotel pool to swim.       No one else was
    present at the scene at the time.    Around 6:00 p.m., William, who
    was holding two-year-old Menelik, began to drown.     The other two
    children, ages eight and four, attempted to rescue their father
    and brother but were unable to do so.
    Another hotel guest, visiting from Arizona, eventually
    came along.   She was able to gain access to the pool area and
    called emergency services.      Emergency personnel began to arrive
    approximately twenty minutes later.      They transported Nandjou's
    son and husband to a nearby hospital in Montreal, where her husband
    was pronounced dead.   Her son was pronounced brain dead two days
    later.
    - 4 -
    Nandjou filed suit in September 2018, in the Superior
    Court of Suffolk County, Massachusetts, against Reluxicorp, Inc.,
    which is the owner of the hotel in question, a franchisee of
    Marriott, and a Canadian corporation that has its principal place
    of business in Montreal; Marriott International, Inc., which is a
    Delaware corporation that has its principal place of business in
    Maryland; and Marriott Worldwide Corporation, which is a wholly
    owned   subsidiary     of   Marriott    International      that   is   both
    incorporated and headquartered in Maryland.        Nandjou's complaint
    asserted wrongful death claims against Reluxicorp and the two
    Marriott defendants, as well as a claim for vicarious liability
    against each of the Marriott defendants based on Reluxicorp's
    status as a Marriott franchisee.       She also brought a claim against
    all   three    defendants   for   negligent   infliction    of    emotional
    distress on the surviving children, as well as a claim against all
    three defendants for the conscious pain and suffering endured by
    Menelik, her two-year-old son who died following the incident at
    the pool. Nandjou's complaint sought, among other types of relief,
    punitive damages.
    The defendants removed the case to the District of
    Massachusetts based on diversity of citizenship on October 25,
    2018.   They then filed a motion in that court in November 2018 to
    dismiss Nandjou's claims based on the doctrine of forum non
    - 5 -
    conveniens and pursuant to Federal Rule of Civil Procedure 12(b)(2)
    for lack of personal jurisdiction over any of the three defendants.
    The     District   Court     denied   that    motion,   but    the
    defendants followed up by filing a motion for reconsideration or
    for a certificate of appealability on their motion to dismiss.            On
    review of the motion for reconsideration, the District Court first
    addressed whether there was personal jurisdiction over the three
    defendants and concluded that there was.                Nandjou v. Marriott
    Int'l, Inc., No. 18-cv-12230-ADB, 
    2019 WL 2918043
    , at *1 (D. Mass.
    July 8, 2019).
    The     District   Court    started   by   concluding   that   the
    Marriott defendants' marketing in Massachusetts concerning the
    Reluxicorp-owned hotel in Canada where the drownings occurred
    could be attributed to Reluxicorp because "the Defendants all used
    the Marriott name and coordinated their business and marketing in
    a manner that may reasonably have created the appearance of
    authority to bind one another."
    Id. at *4.
        Then, after finding
    Massachusetts' long-arm statute satisfied
    , id. at *5,
    the District
    Court   assessed    whether   the     Marriott   defendants'   contacts   in
    Massachusetts via its marketing in that state were sufficient, as
    a matter of federal constitutional due process, to satisfy the
    three prongs of the test for establishing specific jurisdiction
    over those two defendants and Reluxicorp:         relatedness, purposeful
    availment, and reasonableness
    , id. at *5-7.
                   Focusing on the
    - 6 -
    advertisements    promoting   the    Reluxicorp-owned   hotel   that   the
    Marriott defendants had sent to Nandjou's home in Massachusetts,
    the District Court held that they were.
    Id. at *6-7.
    There remained, however, the defendants' motion for
    reconsideration of the District Court's denial of the motion to
    dismiss based on the doctrine of forum non conveniens.                 The
    District Court decided to allow briefing and discovery on that
    issue.
    Id. at *8.
      Thereafter, the District Court granted the
    defendants' renewed motion to dismiss on forum non conveniens
    grounds and ordered dismissal of Nandjou's claims pursuant to that
    doctrine subject to the limitation that the defendants continue to
    submit to personal jurisdiction in Canada on Nandjou's claims in
    connection with the drownings in the parallel action that she had
    filed against them in a court in that country. Nandjou v. Marriott
    Int'l, Inc., No. 18-cv-12230-ADB, 
    2019 WL 5551438
    , at *6 (D. Mass.
    Oct. 28, 2019).
    Nandjou timely appealed from that ruling on November 15,
    2019.    We have jurisdiction under 28 U.S.C. § 1291.
    II.
    A.
    "The doctrine of forum non conveniens . . . permits a
    court to dismiss a case because the chosen forum (despite the
    presence of jurisdiction and venue) is so inconvenient that it
    would be unfair to conduct the litigation in that place."        Howe v.
    - 7 -
    Goldcorp Invs., Ltd., 
    946 F.2d 944
    , 947 (1st Cir. 1991).         "[T]he
    practical effect" of a dismissal on these grounds is to require
    the plaintiff "to file his complaint in a more convenient forum
    elsewhere" in order to obtain relief.
    Id. Congress has codified
       a   federal    district   court's
    authority to transfer a case pursuant to the doctrine of forum non
    conveniens when a federal forum other than the one in which the
    plaintiff has chosen to bring suit is available to hear the claims
    elsewhere in this country.    See Atl. Marine Constr. Co. v. U.S.
    Dist. Ct., 
    571 U.S. 49
    , 60 (2013) (citing 28 U.S.C. § 1404(a)).       A
    federal district court also has the power to dismiss a case
    pursuant to that doctrine, however, when the alternative available
    forum for the case is in a foreign country.          See Sinochem Int'l
    Co. v. Malay. Int'l Shipping Corp., 
    549 U.S. 422
    , 430 (2007).
    Because the doctrine of forum non conveniens permits a
    federal district court to deprive a plaintiff of availing herself
    of her "home forum" even when she otherwise would be legally
    entitled to bring suit in it, the bar for a district court to
    dismiss a suit pursuant to the doctrine is a high one.       Adelson v.
    Hananel, 
    510 F.3d 43
    , 53 (1st Cir. 2007).             The doctrine "is
    intended to 'avoid trials in places so "inconvenient" that transfer
    is needed to avoid serious unfairness,'"
    id. at 52
    (emphasis added)
    (quoting 
    Howe, 946 F.2d at 950
    ), as it guards against not mere
    inconvenience but a plaintiff "by choice of an inconvenient forum"
    - 8 -
    litigating in a manner that would "vex, harass, or oppress the
    defendant by inflicting upon him expense" or unnecessary trouble,
    Gulf Oil Corp. v. Gilbert, 
    330 U.S. 501
    , 508 (1947) (quotation
    marks    omitted).        For   that   reason,     "[i]n   any   balancing   of
    conveniences, a real showing of convenience by a plaintiff who has
    sued in his home forum will normally outweigh the inconvenience
    the defendant may have shown."            Koster v. (Am.) Lumbermens Mut.
    Cas. Co., 
    330 U.S. 518
    , 524 (1947); Nowak v. Tak How Invs., Ltd.,
    
    94 F.3d 708
    , 720 (1st Cir. 1996).
    The   first    step   of   the     requisite   inquiry   under   the
    doctrine entails consideration of whether an adequate alternative
    forum exists to the one that the plaintiff has chosen for her suit.
    Iragorri v. Int'l Elevator, Inc., 
    203 F.3d 8
    , 12 (1st Cir. 2000).
    If there is no adequate alternative forum, then there is no basis
    for dismissal under the doctrine and thus no need to reach the
    second step.      See
    id. In the event
    that there is an adequate
    alternative forum available, however, a court must weigh at the
    second step of the inquiry what are known as the public interest
    factors (such as the relative interests of the local forum and the
    government with jurisdiction over the alternative forum) and the
    private interest factors (such as the burdensomeness to the parties
    and witnesses of having the case proceed in either of the available
    fora).
    Id. - 9 -
                 Dismissal based on the doctrine of forum non conveniens
    is not appropriate when the consideration of the private and public
    interest factors reveals that, as between the plaintiff and the
    moving party, the relative burdens of litigating the case in the
    plaintiff's home forum are in "equipoise," 
    Adelson, 510 F.3d at 54
    , or only marginally favor litigating it in the alternative
    forum, see, e.g., SME Racks, Inc. v. Sistemas Mecanicos Para
    Electronica, S.A., 
    382 F.3d 1097
    , 1103 (11th Cir. 2004) (reversing
    district court's dismissal where "the convenience factors were
    about equal"); Lony v. E.I. Du Pont de Nemours & Co., 
    886 F.2d 628
    ,   640   (3d   Cir.     1989)   ("The   conclusion   that   a   balance   at
    equipoise or tipped toward the defendant favors dismissal is . . .
    an error of law.").         To establish the basis for dismissing a case
    based on forum non conveniens, a defendant bears a "heavy burden,"
    
    Adelson, 510 F.3d at 52
    , and must show that the assessment of the
    relevant     public   and    private    interests   favors   the    case   being
    litigated in the foreign forum to such a degree that it suffices
    to overcome the presumption that the plaintiff is entitled to bring
    her case in her home forum, see 
    Iragorri, 203 F.3d at 15
    .
    We also note, due to its relevance to our analysis below,
    that in undertaking the necessary inquiry into the private interest
    factors at the second step, a court must pay close attention to,
    among other things, the nature of the plaintiff's claims and the
    evidence that would be relied upon to adjudicate them, while giving
    - 10 -
    particular attention to where the witnesses that the parties would
    rely upon are located and how burdensome it would be for them to
    appear in either the home or the foreign forum.                See 
    Gilbert, 330 U.S. at 508
    ; see also Piper Aircraft Co. v. Reyno, 
    454 U.S. 235
    ,
    249 (1981) (explaining that "[e]ach case turns on its facts"
    (alteration in original) (quoting Williams v. Green Bay & W. Ry.
    Co.,   
    326 U.S. 549
    ,   557    (1946)));   
    Howe, 946 F.2d at 951-52
    (carefully examining the elements of the plaintiff's claims in
    evaluating the location of the relevant evidence).                          In that
    assessment, moreover, due consideration must be given to how many
    such witnesses are third parties to the litigation and whether,
    despite      their   third-party    status,    they    would    be    subject    to
    compulsory process in either the home or the foreign forum.                    See,
    e.g., 
    Howe, 946 F.2d at 951
    ("[O]nly Canadian courts, not courts
    within the United States, have the legal power to compel the
    testimony of twelve Canadian potential witnesses who are not under
    the control of any party.").
    Given the nature of the inquiry a court must undertake
    under the forum non conveniens doctrine, we review a motion to
    dismiss a claim on that basis only for an abuse of discretion,
    Interface Partners Int'l Ltd. v. Hananel, 
    575 F.3d 97
    , 101 (1st
    Cir. 2009), due to the district court's greater familiarity with
    the practical realities of the litigation at hand.                          And, we
    emphasize, a district court abuses its discretion in dismissing a
    - 11 -
    case based on forum non conveniens only if it has "(1) failed to
    consider   a   material   factor;   (2) substantially   relied   on   an
    improper factor; or (3) assessed the proper factors, but clearly
    erred in weighing them."    Id. (quoting 
    Adelson, 510 F.3d at 52
    ).
    B.
    There is no question that the District of Massachusetts
    counts as Nandjou's home forum in this case, even though she now
    lives in Georgia.    See 
    Adelson, 510 F.3d at 53
    (explaining that
    although the plaintiff was "not a Massachusetts domiciliary," the
    U.S. District Court for the District of Massachusetts was "still
    deemed a 'home forum' where the alternative [was] foreign"). Thus,
    the District Court correctly articulated the operative standards
    for assessing the motion to dismiss her claims pursuant to the
    doctrine of forum non conveniens, see Nandjou, 
    2019 WL 5551438
    , at
    *2-3, by expressly recognizing at the outset of its opinion that
    Nandjou enjoyed a presumption against being denied her "choice of
    forum" based on concerns about the inconvenience to the defendants
    of litigating in it
    , id. at *2
    (quoting Piper Aircraft 
    Co., 454 U.S. at 241
    ); that the defendants bear a "heavy burden" on a motion
    to dismiss on the grounds of forum non conveniens, id. (quoting
    
    Adelson, 510 F.3d at 52
    ); and that the balance of public and
    private interests must "strongly favor litigating the claim in the
    second forum" to warrant dismissal
    , id. (emphasis added) (quoting
    Adelson, 510 F.3d at 52
    ).
    - 12 -
    Accordingly, we are not persuaded by Nandjou's threshold
    contention that the District Court committed a legal error by
    failing even to apply the presumption against depriving a plaintiff
    of her home forum based on concerns about the inconvenience to the
    defendant.   The District Court did, as Nandjou highlights, state
    at a key point in its analysis that the private interests "weigh
    in favor" of litigating the case in the Canadian forum without
    expressly stating that they strongly favor litigation there.   See
    id. at *5.
      But, when read in context, that statement, like the
    District Court's analysis of the record as a whole, is best
    understood to have been premised on a proper understanding that
    the nature of the showing that the defendants here must make to be
    entitled to have Nandjou's claims dismissed on forum non conveniens
    grounds is a demanding one.
    Nandjou separately contends, however, that the District
    Court clearly erred in applying this demanding standard to the
    facts of this case.   As we will next explain, we agree.
    C.
    There is no dispute between the parties that the District
    Court correctly determined at the first step of the forum non
    conveniens analysis that an adequate alternative forum did exist
    in Canada.   See
    id. at *3.
      In fact, at the time of the District
    Court's ruling, Nandjou had filed a pending action against the
    three defendants in a court in Canada in which she sought recovery
    - 13 -
    for their respective roles in connection with the drownings of her
    husband and son.      See
    id. There also is
    no dispute between the parties that the
    District Court correctly determined, at the second step of the
    analysis,   that    the   public   interest     factors     were     "of   neutral
    weight,"
    id. (capitalization altered), and
    thus that those factors
    were "indeterminant" as to whether they favored litigating the
    case in the Massachusetts or the Canadian forum
    , id. at *5.
                      The
    District    Court     rightly   emphasized      in   so    ruling     that    both
    Massachusetts and Canada had an interest in the outcome of the
    litigation,   as    the   drowning    victims    were      both    Massachusetts
    residents but the drownings were allegedly caused by the negligence
    of a Canadian company in Canada.
    Id. at *4.
    Nandjou    contends,     however,    that     the     District   Court
    clearly erred in concluding that an assessment of the private
    interest factors warranted the dismissal of her claims.                       The
    District Court based the determination that they did on a pair of
    key conclusions -- namely, that "the most important witnesses will
    be those who can speak to the hotel's policy regarding pool
    supervision and the exact circumstances on the day of the accident,
    including the cause of Plaintiff's family members' deaths" and
    that the "Defendants have demonstrated that the majority of those
    relevant witnesses are Canadian residents."
    Id. at *6.
    - 14 -
    
                We conclude that Nandjou is right that the District
    Court's assessment of the private interest factors -- and thus its
    assessment of the second step of the requisite inquiry as a whole
    -- is clearly wrong.        To explain why, it helps to separate out
    Nandjou's claims.
    1.
    To start, as Nandjou points out, the District Court's
    analysis of the private interest factors cannot suffice to justify
    the dismissal of her vicarious liability claim against each of the
    two Marriott defendants.          This claim is, of course, dependent on
    a showing of Canadian-based Reluxicorp's underlying liability.               In
    that respect, it, like Nandjou's other claims, depends on a showing
    about the circumstances at the hotel pool on the day of the
    accident in Montreal.       But, in its nature, this claim -- unlike
    the others that Nandjou brings -- also is dependent on showings
    that relate to the relationship between Reluxicorp as a Marriott
    franchisee and the Marriott defendants, given that whether the
    Marriott defendants are vicariously liable is a function of the
    nature of the franchisor-franchisee relationship between them and
    Reluxicorp.
    As Nandjou highlights, the evidence bearing on that
    relationship concerns, among other things, the extent to which the
    Marriott defendants held out that Canadian franchisee to potential
    customers   as   if   it   were    owned,     operated,   and   controlled   by
    - 15 -
    Marriott.     See Thalin v. Friden Calculating Mach. Co., 
    153 N.E.2d 658
    ,   661    (Mass.   1958)   (evaluating   whether    plaintiff   had
    established franchisor's liability for franchisee's negligence by
    considering, among other things, whether there was evidence "of
    present or past holding out" by the franchisor).       That evidence in
    turn depends on testimony from witnesses who, so far as the record
    reveals, are not all or even in the main located in Canada, given
    that each of the Marriott defendants is based in the United States,
    not Canada.     Thus, when the full picture is considered as to the
    witnesses in play for the vicarious liability claim against each
    of the Marriott defendants, we do not see a basis for concluding
    that the presumption in favor of having the case litigated in the
    home forum chosen by the plaintiff has been overcome.       Cf. Duha v.
    Agrium, Inc., 
    448 F.3d 867
    , 879 (6th Cir. 2006) ("The dismissal of
    distinct claims effectively omitted from the forum non conveniens
    analysis is not within the district court's discretion.").
    2.
    That said, the District Court's order of dismissal based
    on forum non conveniens was not limited to the claim for vicarious
    liability against the Marriott defendants.        It encompassed all
    claims against all defendants, and the other claims -- including
    the ones brought against the Marriott defendants and those brought
    against Reluxicorp -- are for conduct that occurred in Canada and
    do not so directly target conduct that concerns the relationship
    - 16 -
    between Reluxicorp and the Marriott defendants.             Moreover, if it
    were proper to dismiss those claims based on forum non conveniens,
    then it might well be proper to dismiss the suit as a whole on
    that basis, given the relationship between the vicarious liability
    claim against both of the Marriott defendants and the other claims
    that Nandjou brings.      See U.S.O. Corp. v. Mizuho Holding Co., 
    547 F.3d 749
    , 750 (7th Cir. 2008) ("There is no reason for identical
    suits to be proceeding in different courts in different countries
    thousands of miles apart."); cf. Olympic Corp. v. Societe Generale,
    
    462 F.2d 376
    , 379 (2d Cir. 1972) ("[T]he benefits of impleader
    might be taken into account in a close case in deciding whether or
    not to dismiss for forum non conveniens . . . .").            Nevertheless,
    we   cannot    sustain   the   District   Court's   forum   non   conveniens
    determination as to the other claims either.
    In concluding that the balance of witnesses who would
    supply the most important testimony for the remaining claims were
    Canadians who were not themselves parties to -- or employees of
    parties to -- the suit, the District Court made the following
    tally.    It noted that seven of the eight potential witnesses
    referred to in a Canadian police report concerning the incident at
    the pool were from Canada and that only one, the Arizona resident
    whom we mentioned above, was from the United States.               Nandjou,
    
    2019 WL 5551438
    , at *5.        It then further noted that the coroner
    and all of the doctors who treated the victims of the drownings
    - 17 -
    were   based   in     Montreal    and     were    unwilling      to   travel     to
    Massachusetts.
    Id. In addition, it
    noted that none of these
    Canadian witnesses was an employee of a party to the suit and that
    a number of other non-party witnesses were located in Canada,
    including the first responders who were on the scene soon after
    the drownings, six police officers who investigated the drownings,
    and the building inspector.
    Id. Thus, even setting
    aside the
    employees of the defendants who were potential witnesses, the
    District Court concluded that there were twenty-five Canadian
    third-party witnesses who potentially could provide testimony
    relevant to the determination of liability on these claims.
    Id. By contrast, the
    District Court concluded, Nandjou had
    identified only:       one U.S.-based witness (from Arizona and not
    Massachusetts) who was present at the pool in the aftermath of the
    drownings; her two children; two Massachusetts residents (Kim and
    Gregg Pierce, who were guests at the hotel at the time); and a
    number of damages witnesses.
    Id. at *6.
         The District Court
    further determined -- supportably -- that the Arizona resident's
    testimony did not render duplicative the testimony of the Canadian
    residents who arrived on the scene at the pool, given that the
    Arizona    witness    stated     in   a     deposition    that    she   was     not
    continuously present there in the aftermath of the drownings, as
    she left for periods of time to call the police and to help the
    children   call     their   mother.
    Id. The District Court
       also
    - 18 -
    discounted the significance of the Pierces' testimony on the ground
    that "they did not actually observe the accident, but merely
    observed the aftermath, including the first responders at the
    scene."
    Id. And, finally, the
    District Court noted that, although
    Nandjou had identified a number of Massachusetts residents who
    could supply evidence bearing on the case in addition to the
    Pierces and her children, they could do so only as to "damages"
    and not liability.
    Id. For these reasons,
    the District Court concluded that the
    balance of the private interest factors sufficed to support having
    the case litigated in Canada rather than Massachusetts and thus
    dismissing Nandjou's claim pursuant to the doctrine of forum non
    conveniens.
    Id. After all, the
    District Court determined, there
    were an overwhelming number of third-party Canadian witnesses who
    could testify to matters concerning liability.
    Id. This accounting, however,
    gives too little weight to the
    fact that the only potential witnesses who were present when the
    drownings occurred were Nandjou's two surviving children.    It is
    true that they are not third parties. But, they are also obviously
    central witnesses who hail from this country rather than Canada.
    And they have the status as key witnesses not only when it comes
    to the issue of damages, given their special capacity to describe
    the trauma that they endured as a result of the events that
    transpired, but also as to liability, because they alone can
    - 19 -
    describe the scene as it looked at the moment the drownings
    occurred and until any assistance came.
    In addition, while we agree with the District Court that
    the witness from Arizona cannot be said to render testimony from
    all others who arrived on the scene in the immediate aftermath of
    the tragedy duplicative, she is herself a significant third-party,
    non-Canadian witness to the events.        In fact, she was the first to
    arrive   at    the   scene   after   the   drownings   occurred.    The
    Massachusetts-based Pierces are similarly potentially significant
    third-party witnesses, as they, too, were on the scene in the
    immediate aftermath of the drownings and as they are not in any
    evident respect less well positioned than any of the other hotel
    guests from Canada who arrived in the wake of the drownings to
    give relevant testimony bearing on the conditions at the pool at
    that time.
    In total, then, Nandjou has identified five non-Canadian
    witnesses who are well positioned to provide live testimony as to
    liability, of whom only two are not third parties.        Additionally,
    those two witnesses are not only the only ones who were actually
    present when the drownings occurred but also are young children
    who, if forced to testify in Montreal, would be required to return
    to the country of their loved ones' deaths.         Cf. Guidi v. Inter-
    Cont'l Hotels Corp., 
    224 F.3d 142
    , 145 (2d Cir. 2000) (reversing
    a dismissal based on forum non conveniens in part because the
    - 20 -
    district court failed to consider the "emotional burden" it would
    impose on the plaintiffs to return to Egypt, where their loved
    ones were killed).
    Moreover, although the District Court discounted the
    numerous additional Massachusetts-based residents who could supply
    evidence concerning damages, Nandjou, 
    2019 WL 5551438
    , at *6, we
    do   not   see   why   the   fact   that   these   witnesses   would   not   be
    testifying as to liability provides a basis for concluding that
    the burdensome nature of having them appear in a Canadian court is
    of little importance to the inquiry. We are not aware of authority
    that suggests that, under the doctrine of forum non conveniens,
    testimony from witnesses regarding damages is inherently less
    crucial than testimony from witnesses regarding liability.
    Insofar as the defendants contend that the distinction
    between liability and damages witnesses does matter to the inquiry
    into the balance of private interests, they appear to rely on
    Iragorri v. International 
    Elevator, 203 F.3d at 16
    .            But, they are
    wrong to do so, given how the facts of that case differ from this
    one.
    There, we reviewed a district court decision dismissing
    a case on forum non conveniens grounds that arose from an accident
    in which the plaintiff's late husband fell to his death in an
    elevator shaft in Colombia and sued the company that maintained
    the elevator in the District of Maine.
    Id. at 10-11.
       With respect
    - 21 -
    to the private interest factors, we noted that "problems of proof
    would be exacerbated, not ameliorated, by a trial in Maine," in
    part   because    "crucial   liability     witnesses"     were    located    in
    Colombia, because their "credibility [would be] under attack" at
    trial, and because, if the trial were held in Maine, they "most
    likely would appear, if at all, by video deposition with the
    assistance   of   a   translator."
    Id. at 16.
        By     contrast,   we
    explained, the plaintiff's "suggested witnesses were experts,
    concerned primarily with damages," and their "testimony would be
    more amenable to depositions and translation."
    Id. This review of
    our analysis in Iragorri shows that the
    key distinction there was not that one set of witnesses would be
    providing    evidence   about   liability   while   the    other    would    be
    providing evidence about damages only.        Rather, what mattered was
    that the liability witnesses would need to provide live testimony,
    while the damages witnesses were less likely to need to do so.
    Here, however, there is no similar ground for distinguishing
    between the sets of witnesses, so far as the record reveals.
    Rather, live testimony from the damages witnesses for Nandjou may
    be crucial to their presentation, given that they plan to provide
    evidence about the type of person the victim was and the effect of
    his loss on his wife and daughters.         And the District Court made
    no finding that the Canadian non-party liability witnesses for the
    defendants whom it concluded were "most important" would be unable
    - 22 -
    to provide the critical aspects of that testimony through means
    other than live testimony.     See Nandjou, 
    2019 WL 5551438
    , at *6.
    Thus, on this record, we do not agree that there is a
    supportable basis for saying that the defendants have met their
    heavy burden to show that concerns about private convenience
    justify depriving Nandjou of the forum she chose, which is in this
    country.   That is especially true given the critically important
    role that her young children may play at trial as witnesses, as
    they alone are in a position to testify about the conditions at
    the pool at the moment of the drownings.
    Nor does the relevant precedent indicate otherwise.    It
    is evident that this case stands in stark contrast to those in
    which we have affirmed a district court's dismissal of an action
    based on forum non conveniens.     For example, in Howe v. Goldcorp
    Investments, the principal analogue on which the defendants rely,
    we concluded that dismissal was not an abuse of discretion where
    "most of the evidence [was] in Canada and most of the witnesses
    [were] in 
    Canada." 946 F.2d at 951
    .      Indeed, except for the
    plaintiff, "no resident of the United States 'ha[d] knowledge
    relevant to the matters alleged in the amended complaint.'"
    Id. (internal citation omitted).
       We found that the action had "little
    to do with Massachusetts or any other jurisdiction in the United
    States" but had "a great deal to do with Canada."
    Id. at 952-53. - 23 -
              The same cannot be said here. As we have just cataloged,
    the most critical witnesses reside in the United States, and there
    is no reason to discount the potential import of the several third-
    party, non-Canadian witnesses who were present at the pool in the
    drownings' immediate aftermath or the numerous Massachusetts-based
    witnesses whose live testimony bears on damages.     Moreover, while
    the defendants have estimated that twenty-five non-party witnesses
    reside in Canada, they have not explained why live testimony from
    all of those witnesses is critical.     See 
    Iragorri, 203 F.3d at 16
    .
    Thus, we conclude that the District Court "clearly erred in
    weighing" the private interests involved, 
    Adelson, 510 F.3d at 52
    ,
    and that the balance of public and private interest factors did
    not warrant dismissal.
    III.
    The defendants contend that we may affirm the District
    Court's dismissal of Nandjou's claims on the alternative ground
    that that there is no personal jurisdiction over them.      See John
    Hancock Life Ins. Co. v. Abbott Lab'ys, 
    863 F.3d 23
    , 34 (1st Cir.
    2017) ("Although [the appellee] has not filed a cross-appeal, we
    have jurisdiction to consider a prevailing party's alternative
    arguments in defense of a judgment where, as here, the arguments
    were made below.").   We conclude, however, that the District Court
    did not err in ruling otherwise, Nandjou, 
    2019 WL 2918043
    , at *7,
    - 24 -
    and thus that we may not affirm its dismissal of Nandjou's claim
    on this independent ground.
    A.
    The District Court applied the "prima facie" standard to
    assess    the    sufficiency    of    Nandjou's     showing      as   to   personal
    jurisdiction.
    Id. at *1.
        Accordingly,       the   District     Court
    evaluated "whether the plaintiff has proffered evidence which, if
    credited, is sufficient to support findings of all facts essential
    to personal jurisdiction."
    Id. (quoting Bluetarp Fin.,
    Inc. v.
    Matrix Constr. Co., 
    709 F.3d 72
    , 79 (1st Cir. 2013)). Both parties
    accept that the application of this standard was appropriate.                   We
    thus     "must    accept    the       plaintiff's     (properly        documented)
    evidentiary proffers as true," Foster-Miller, Inc. v. Babcock &
    Wilcox Can., 
    46 F.3d 138
    , 145 (1st Cir. 1995), and "construe them
    in the light most congenial to the plaintiff's jurisdictional
    claim," Mass. Sch. of L. at Andover, Inc. v. Am. Bar Ass'n, 
    142 F.3d 26
    , 34 (1st Cir. 1998).              We review the District Court's
    application of that standard to the record de novo.                   
    Adelson, 510 F.3d at 48
    .
    Because the District Court's subject-matter jurisdiction
    in this case was premised on diversity of citizenship, we act as
    the    "functional    equivalent"        of    a   state    court     sitting    in
    Massachusetts for the purpose of assessing personal jurisdiction.
    Kuan Chen v. U.S. Sports Acad., Inc., 
    956 F.3d 45
    , 54 (1st Cir.
    - 25 -
    2020) (quoting Baskin-Robbins Franchising LLC v. Alpenrose Dairy,
    Inc., 
    825 F.3d 28
    , 34 (1st Cir. 2016)). We therefore must evaluate
    whether the exercise of personal jurisdiction over the defendants
    complies with both the requirements of the Massachusetts long-arm
    statute and the Due Process Clause of the Fourteenth Amendment to
    the U.S. Constitution.
    Id. The defendants do
    not argue that the long-arm statute
    imposes any limit that the Federal Constitution does not.   As any
    argument to the contrary is waived, we "train the lens of our
    inquiry exclusively on the federal constitutional analysis."
    Id. For there to
    be personal jurisdiction over a defendant
    as to a claim, the Due Process Clause requires that the defendant
    must "have sufficient minimum contacts with the state, such that
    'maintenance of the suit does not offend "traditional notions of
    fair play and substantial justice."'"     
    Adelson, 510 F.3d at 49
    (quoting Int'l Shoe Co. v. Washington, 
    326 U.S. 310
    , 316 (1945)).
    Such contacts must be sufficient to sustain a theory of either
    general or specific jurisdiction.   See Kuan 
    Chen, 956 F.3d at 55
    .
    In view of Daimler AG v. Bauman, 
    571 U.S. 117
    (2014), however,
    Nandjou pursues a theory of specific personal jurisdiction only.
    Thus, for each claim and each defendant, she must make a tripartite
    showing: that the claim is sufficiently related to the defendant's
    contacts with Massachusetts, that the defendant's contacts with
    Massachusetts constitute purposeful availment of the protections
    - 26 -
    and privileges of conducting business in the Commonwealth, and
    that the exercise of jurisdiction there is reasonable.          
    Nowak, 94 F.3d at 712-13
    . The District Court concluded that, under the prima
    facie standard, Nandjou met the bar on all three fronts for all of
    her claims against all of the defendants.          See Nandjou, 
    2019 WL 2918043
    , at *7.
    B.
    We start with the claims Nandjou brings against the
    Marriott defendants.     The defendants do not attempt to distinguish
    between the claims against them in developing their only argument
    in support of their assertion that the District Court erred in
    finding that Nandjou made the requisite showing as to personal
    jurisdiction over them. That argument concerns the showing Nandjou
    makes as to the relatedness prong.          Moreover, in pressing that
    argument, the defendants contend only that the District Court erred
    in   finding   that   their   marketing    activities   in   Massachusetts
    suffice to show that their in-Massachusetts contacts satisfy the
    relatedness requirement.       Thus, we address only that portion of
    the District Court's analysis in evaluating whether there is
    personal jurisdiction as to the Marriott defendants.          See Marek v.
    Rhode Island, 
    702 F.3d 650
    , 655 (1st Cir. 2012) (explaining that
    "issues adverted to in a perfunctory manner, unaccompanied by some
    effort at developed argumentation, are deemed waived" (quoting
    United States v. Zannino, 
    895 F.2d 1
    , 17 (1st Cir. 1990))).
    - 27 -
    The Marriott defendants emphasize that Nandjou's claims
    against them focus on duties that Nandjou contends that they
    breached through their actions (or failures to act) in Canada, not
    Massachusetts.       They also emphasize that the Massachusetts-based
    activity on which the District Court relied in finding that it had
    personal jurisdiction over them consists of a marketing campaign
    that, even if it induced Nandjou's family to stay at the hotel in
    Montreal and to use its pool, did not itself play anything more
    than a but-for role in causing the drownings themselves.             The
    Marriott defendants thus contend that those Massachusetts-based
    contacts have too attenuated a connection to the tortious conduct
    alleged to satisfy the due process-based, personal jurisdiction
    requirement that in-forum contacts must be related to the claim at
    issue.
    We may skip over the fact that among the claims that
    Nandjou has brought against the Marriott defendants is a claim for
    vicarious liability, which depends in significant part on the
    nature   of    the   franchisor-franchisee   relationship   rather   than
    solely a breach of duty that occurred only in Canada.         For, even
    if we accept the premise on which the defendants' assertion of
    error by the District Court rests, and thus focus our analysis
    exclusively on the connection between the Marriott defendants'
    marketing activity in Massachusetts and the claims against them
    that seek to hold them liable for their own breaches of duty rather
    - 28 -
    than vicariously for the breach of duty by Reluxicorp, we are not
    persuaded by the contention that Nandjou failed to make the
    requisite showing of relatedness.
    The Marriott defendants are correct that, in Nowak v.
    Tak How Investments, we noted that a "proximate cause standard
    better comports with the relatedness inquiry" with respect to tort
    claims than a pure "'but for' requirement," which "has in itself
    no limiting 
    principle." 94 F.3d at 715
    .   For that reason, the
    Marriott defendants contend that the fact that their marketing
    activities in Massachusetts were at most a but-for cause of the
    drownings -- rather than a proximate one -- precludes us from
    treating those activities as the kind of contacts that could
    satisfy the relatedness requirement.
    But, as the Marriott defendants themselves acknowledge,
    we explained in Nowak that "strict adherence to a proximate cause
    standard in all circumstances is unnecessarily restrictive" and
    that "the first prong of the jurisdictional tripartite test is not
    as rigid" as the proximate cause inquiry in the tort context.
    Id. Thus, even if
    the Marriott defendants are right that their direct-
    mail campaign, in and of itself, did not proximately cause the
    drownings, that fact alone would not end our inquiry with respect
    to whether that campaign could nonetheless suffice to satisfy the
    relatedness requirement.
    - 29 -
    The   Marriott     defendants    do   not   dispute    that   Nowak
    recognized that where a corporation "directly targets residents in
    an ongoing effort to further a business relationship, and achieves
    its purpose, it may not necessarily be unreasonable to subject
    that corporation to forum jurisdiction when the efforts lead to a
    tortious result,"
    id., even though they
    may not have proximately
    caused it.    But, the Marriott defendants emphasize, Nowak poses no
    problem for them because that case involved a much more extensive
    course of dealing between the plaintiff (also the family member of
    a patron of a foreign hotel who drowned in its pool) and the
    defendant than this one does.         They thus argue that Nowak may not
    be extended to facts like those before us here, and they warn that
    doing so would effectively place any hotel that advertises on the
    internet at risk of being sued in any forum, anywhere in the
    country, where a guest is domiciled and books a reservation in
    response to that online marketing.
    Nowak made clear, however, that the precise facts of
    that case do not necessarily define the outer limits of the
    circumstances      in   which    a   defendant's    actions   in     the   forum
    jurisdiction to cultivate a plaintiff's business may be said to be
    related to a resulting tort claim even though those actions did
    not proximately cause the tort.           See
    id. at 716.
             It expressly
    stated that "[i]t may be that other kinds of fact patterns will be
    - 30 -
    found to meet the basic factor of foreseeability, but we have no
    occasion here to pronounce more broadly."
    Id. In this case,
    the Marriott defendants' activity that
    provides the basis for the District Court's conclusion that the
    relatedness requirement has been met does not consist of their
    merely having posted an advertisement for the Canadian hotel on
    the internet for all the world to see.      Instead, that activity,
    the District Court supportably found, see Nandjou, 
    2019 WL 2918043
    ,
    at *2, *5, consists of the Marriott defendants deliberately having
    cultivated business from Nandjou and her family in Massachusetts
    by sending direct mail to her home in the Commonwealth that
    promoted the very hotel in which the drownings occurred and that
    even described that hotel's pool.
    Nor is this a case in which such a direct in-forum-state
    attempt to cultivate the plaintiff's business played no role in
    the plaintiff's decision to enter into the business relationship
    that grounds her tort claims.       The record suffices to provide
    support for Nandjou's claims that, through those materials, the
    Marriott defendants induced her family to stay at that hotel.
    We thus conclude that, while the nature of the business
    cultivation in Massachusetts by the Marriott defendants differed
    from the nature of the business cultivation in the forum state by
    the defendants in Nowak, the District Court correctly held that,
    per   Nowak,   Marriott's   contacts    with     Massachusetts   were
    - 31 -
    sufficiently related to Nandjou's claims against the Marriott
    defendants to support the exercise of specific jurisdiction over
    them.   See Nandjou, 
    2019 WL 2918043
    , at *5-6.   As a result, there
    is no lack of personal jurisdiction over the Marriott defendants.
    C.
    That brings us, then, to the question of whether there
    is personal jurisdiction over Reluxicorp. In contending that there
    is not, Reluxicorp does not deny that, "[f]or purposes of personal
    jurisdiction, the actions of an agent may be attributed to the
    principal." Daynard v. Ness, Motley, Loadholt, Richardson & Poole,
    P.A., 
    290 F.3d 42
    , 55 (1st Cir. 2002).   It thus accepts that the
    Marriott defendants' contacts in Massachusetts could be imputed to
    it if those defendants were acting as its agents when engaged in
    those contacts.   But, Reluxicorp contends that, even still, there
    is no personal jurisdiction over it.
    Reluxicorp argues that is the case in part because it
    contends that the Marriott defendants' contacts with Massachusetts
    through their marketing efforts were too attenuated from the
    alleged tortious conduct to support a finding of relatedness even
    as to the Marriott defendants.    But, as we have just explained,
    there is no force to that contention, and so, we must address
    Reluxicorp's additional assertion that the Marriott defendants'
    marketing activities in Massachusetts may not be attributed to it.
    - 32 -
    Here, Reluxicorp first contends that Nandjou has failed
    adequately to establish that the Marriott defendants were acting
    as Reluxicorp's agents in conducting the direct-mail marketing
    campaign which led them to send brochures to Nandjou's home in
    Massachusetts advertising the Montreal hotel and highlighting its
    pool.    Reluxicorp does not contest Nandjou's assertion that the
    hotel had entered into a franchise agreement with the Marriott
    defendants that obligated Marriott to undertake marketing efforts
    on   behalf    of    Reluxicorp     in   return   for   payment    and   which
    specifically identified those efforts as potentially including
    direct mail.     Reluxicorp stresses instead that it did not dictate
    -- and did not have the contractual right to dictate -- any of the
    specifics of the marketing methods that the Marriott defendants
    would deploy.       Thus, Reluxicorp contends, the Marriott defendants
    were not acting as Reluxicorp's agents in marketing the Montreal
    hotel to Nandjou's family as they did, because Reluxicorp lacked
    control over the marketing methods chosen by them.
    As support for this assertion, Reluxicorp relies on
    Theos & Sons, Inc. v. Mack Trucks, Inc., 
    729 N.E.2d 1113
    (Mass.
    2000),   which      holds   that,   under   Massachusetts   law,   an    agency
    relationship requires that "the agent is to act on behalf and for
    the benefit of the principal, and subject to the principal's
    control."
    Id. at 1119.
             Reluxicorp's assertion on this score
    appears to depend on the implicit legal premise that Massachusetts
    - 33 -
    agency law is determinative in this case of whether an agency
    relationship exists for purposes of the inquiry that the Due
    Process Clause requires us to undertake in determining personal
    jurisdiction.        Or, perhaps Reluxicorp means to contend that Theos
    & Sons may be understood to set forth a view of the law of agency
    that is widely shared.
    But, even assuming that Theos & Sons is dispositive of
    whether,   for       purposes    of   personal      jurisdiction,            the     Marriott
    defendants      were     Reluxicorp's         agents      in        carrying   out     their
    Massachusetts-based marketing, Reluxicorp acknowledges that the
    minimum    contacts      of   one     defendant     in     a    forum       state     can   be
    attributed      to     another    even    if      there        is     no    actual    agency
    relationship between them in place.                    In particular, it accepts
    that   such    imputation        of   those    contacts         can    be    proper    under
    principles of agency by estoppel.                 See 
    Daynard, 290 F.3d at 56
    -
    57.    And Reluxicorp also accepts that, under those principles, a
    "person who is not otherwise liable as a party to a transaction
    purported to be done on his account[] is nevertheless subject to
    liability to persons who have changed their positions because of
    their belief that the transaction was entered into by or for him,
    if" either "he intentionally or carelessly caused such belief" or
    if he, "knowing of such belief and that others might change their
    positions because of it, . . . did not take reasonable steps to
    - 34 -
    notify them of the facts."
    Id. at 56
    (quoting Restatement (Second)
    of Agency § 8(B) (1958)).
    Thus, if Nandjou and her husband acted in reliance on
    the notion that the direct-mail campaign conducted by the Marriott
    defendants was undertaken by Reluxicorp, even if Reluxicorp did
    not specifically authorize it, that contact with Massachusetts
    potentially can be attributed to Reluxicorp for the purposes of
    evaluating whether personal jurisdiction exists over Reluxicorp in
    this suit.    In other words, to show that the Marriott defendants'
    direct-mail-based contacts in Massachusetts are also Reluxicorp's,
    Nandjou need only demonstrate -- to the degree required under the
    prima facie standard -- that Reluxicorp either intentionally or
    carelessly    led   her   and   her    husband   to   believe   that   it   was
    responsible for the advertisements sent to their home promoting
    the hotel in Montreal or, at least, that it failed to take
    reasonable steps to correct their perception that it was.
    As the District Court rightly determined, see Nandjou,
    
    2019 WL 2918043
    , at *4, the record supportably shows that Nandjou
    and her husband reasonably understood the advertisements that they
    received at their home from the Marriott defendants to be a
    solicitation of their business from a Marriott-owned and Marriott-
    operated property in Montreal.            See
    id. And, the record
    also
    suffices to show, they changed their position based on that
    perception -- Nandjou's husband made a reservation to stay there
    - 35 -
    at least in part because the couple determined from the brochures
    that the Montreal hotel "was an attractive Marriott hotel that
    [they] would like to visit, and that the hotel and its amenities,
    including its pool, were clean and safe."
    Moreover, the record supportably shows, Reluxicorp's own
    conduct contributed to Nandjou and her husband's understanding.
    Reluxicorp held out its hotel in Montreal as being a Marriott
    property by identifying itself with the descriptor "The Residence
    Inn by Marriott" and through its use of Marriott branding and
    signage at its physical location.              And Reluxicorp does not develop
    any argument that it did not know that its actions in that regard
    could lead prospective customers to believe that it was operated
    by   Marriott    or    that   it   made   any     effort      to    ensure   that   the
    advertising      that    it    contractually           authorized      the   Marriott
    defendants      to    undertake    on   its     behalf       (which   expressly     was
    understood to include direct mailings) clarified that it was an
    independent     entity.       Indeed,     so     far    as    the   record   reveals,
    Reluxicorp benefited from affiliating itself with Marriott by
    virtue of the goodwill associated with that brand.
    Reluxicorp does argue that Nandjou's family could not
    have believed that the marketing materials were sent on its behalf
    by Marriott because the family did not realize that Reluxicorp and
    Marriott were separate businesses.               But, that fact, even if true,
    hardly helps Reluxicorp's position.               The allegation that Nandjou
    - 36 -
    and her husband understood the Montreal hotel and Reluxicorp to be
    a single entity only reinforces our conclusion that the record
    supportably     shows   that    the    couple     believed   the    advertising
    campaign was undertaken "by or for" the Montreal hotel and that
    Reluxicorp's own actions facilitated that understanding.                       See
    
    Daynard, 290 F.3d at 56
    (quoting Restatement (Second) of Agency
    § 8(B) (1958)).
    As a result, even if this case cannot properly be
    considered one in which Reluxicorp "intentionally . . . caused
    [the] belief" that it was entreating Nandjou and her husband to
    visit, Reluxicorp certainly "did not take reasonable steps" to
    disabuse the couple of that notion.             See
    id. (quoting Restatement (Second)
    of Agency § 8(B) (1958)).               We therefore conclude that
    Marriott's    direct-mail      efforts    can    properly    be    evaluated   as
    Reluxicorp's own contacts with Massachusetts for the purpose of
    assessing personal jurisdiction.
    Thus, we hold that the District Court properly concluded
    that the relatedness requirement was met as to Reluxicorp based on
    the Marriott defendants' direct-mail marketing of the Canadian
    hotel to Nandjou and her husband at their home in Massachusetts,
    just as we hold it properly concluded that requirement was met
    based on those same activities as to the Marriott defendants
    themselves. And, that being so, we conclude that there is no basis
    for   reversing     the   District       Court's     finding       of   personal
    - 37 -
    jurisdiction over Reluxicorp, just as there is no basis for doing
    so as to its finding of personal jurisdiction over the Marriott
    defendants, as Reluxicorp offers no other reason that could supply
    a basis for our concluding otherwise.
    IV.
    We affirm the judgment of the District Court denying the
    defendants' motion to dismiss for lack of personal jurisdiction
    and we reverse the judgment of the District Court granting the
    defendants' motion to dismiss on forum non conveniens grounds.
    Each party shall bear their own costs."
