Teodora-Evdokija

Theodora Nemanjić (1330 – after 1381) was the youngest daughter of King Stefan Uroš III Dečanski and Maria Palaiologina, and a half-sister of Stefan Dušan. In 1347 she married Despot Dejan, whom Dušan made sebastokrator, and bore him Jovan Dragaš and Constantine Dragaš, who ruled the eastern marches after Maritsa, and a daughter, Teodora.

Long widowed, she became a nun as Evdokija. Through Constantine's daughter Helena Dragaš she was the great-grandmother of the last Byzantine emperors John VIII and Constantine XI.
