2. MARIA Komnene ([1044/49]]-[18 Aug] ---). Nikeforos Bryennios names (in order) "Maria, Eudocia et Theodora" as the three daughters of "Ioanni" and his wife Anna[62]. Nikeforos Bryennios records the marriage of "Ioannes…Comnenus curopalates…maior…natu [filia] Maria" and "Taronitæ Michaeli"[63]. Her origin is also deduced from the Alexeiad naming "Mikhael" as the husband of the niece of the Komnenoi brothers, although the text does not name her or her daughter[64]. The relationship is clarified in a later passage which records that "Taronites…had married the emperor's sister Maria"[65]. It is not known whether Maria was older or younger than her brother Isaakios. The date of her marriage is estimated approximately based on her supposed birth date. She became a nun as ANNA. The list of obituaries of the monastery of Christ Philanthropos, founded by Empress Eirene Doukas, records the death 18 Aug of "kyras Marias tis autadelfou tou basileos"[66]. This entry is assumed to relate to Maria, sister of Emperor Alexios I, but it is not an ideal match as it is surprising that it does not record her monastic name. No indication has been found of the year of Maria’s death.
