7. MARIA (-[young]). The Masarelli Vatican manuscript names (in order) Theodora, Maria, and Eirene as the daughters of Theodoros & his wife[655]. The manuscript Vaticanus latinus 4789 records that “le seigneur Georges Cantacuzène...et son frère le grand domestique de Constantinople” had three sisters and that they arranged the marriage of “l’autre sœur [=la troisième]...au roi d’Ibérie”, adding that the couple “procréèrent des enfants qui tous disparurent, les turcs les ayant pris”[656]. Laurent comments that “ce...renseignement me paraît nouveau et bon, quoi qu’il m’ait été impossible d’en contrôler le bien fondé”, speculates on the possible identity of her husband assuming that the information is correct, but concludes (at least in respect of the alleged disappearance of the couple’s supposed children at the hands of the Turks) that “je croirais volontiers que Busac [author of the manuscript] a confondu...les destins de deux sœurs: celui de la reine anonyme de Géorgie avec celui de l’impératrice de Trébizonde Hélene”[657]. If the information is correct, there are several possible candidates for the husband of this daughter (see the document GEORGIA) but further speculation on his identity appears pointless unless further corroboration about the marriage emerges.
