them "happier than all people". Her sudden death in the spring or summer of 1252 plunged Theodore into grief. She gave birth to four or five daughters, and one son. Their children were: Irene, who married Constantine Tikh of Bulgaria, was Emperor Michael VIII's implacable enemy until her death around 1270. Maria, who married Nikephoros I of Epirus, deceased between early in 1257 and 1265. Theodora was married off by Michael VIII to a Moreot nobleman, Maïos Débélikourtos, according to Pachymeres and Nicephorus Gregoras. Historian Albert Failler identifies him as Matthew of Mons who held the Barony of Veligosti in the Principality of Achaea. Eudoxia first married Count William-Peter of Ventimiglia, who died around 1280. Her second husband, Roger Arnau, Count of Pallars, died in 1288. The widowed Eudoxia had a love affair with the Aragonese admiral Bernat de Serria. She died in 1309. A Bulgarian boyar, Despot Jacob Svetoslav, married Theodore's unnamed daughter, according to Pachymeres. She may have been Theodore's illegitimate daughter, because other Byzantine historians failed to mention her. Theodore's only son, John, survived his mutilation, but he spent the rest of his life in prison. He died around 1309. See also List of Byzantine emperors References Sources Further reading Dimiter G.
