Alexios Palaiologos
Alexios Palaiologos (c. 1140 – before 1203) was a Byzantine sebastos who rose to the high naval rank of megas doux, probably between 1185 and 1190. Around 1180 he married Irene Komnene, daughter of the sebastos John Kantakouzenos and Maria Komnene, a grand-niece of the Emperor Manuel I Komnenos.
Their sons were Michael and Andronikos, the megas domestikos who fathered the Emperor Michael VIII. The typikon with which Michael VIII refounded the monastery of the Archangel Michael names Alexios as the emperor's grandfather.
The typikon also records that Alexios restored the house and ended his life there as the monk Antonios. Irene died a nun.
