John V Palaiologos
Theodora remained a Christian after her marriage, and was active in supporting the Christians living under Ottoman rule. In 1347 she gave birth to her only son, Şehzade Halil, who was captured by Genoese pirates for ransom while still only a child. The Byzantine emperor John V Palaiologos was instrumental in his eventual release. Later, Halil married Irene, a daughter of John V Palaiologos and Theodora's sister, Helena Kantakouzene.
