  Research Notes:

Nikeforos Bryennios names (in order) "Maria, Eudocia et Theodora" as the three daughters of "Ioanni" and his wife Anna. Her date of birth can be estimated only approximately. Nikeforos Bryennios records the marriage, after her father's death "matris voluntate", of "Ioannes…Comnenus curopalates…postrema Theodora [filia]" and "Constantino Diogenis iam imperatoris filio". The Alexeiad names "Theodora, the emperor's sister…widow of Diogenes's murdered son" when recording her reaction to an imposter pretending to be her husband who had been killed in Antioch. The text names the son "Leon" but it is clear from the context that it must refer to Konstantinos, who was killed when his half-brother Leon was still an infant. She became a nun as XENA. ¹
