Constantine XI Palaiologos
Andronikos was amongst those who advised Emperor Constantine XI Palaiologos to take for his third wife Anna, the daughter of Emperor David of Trebizond, instead of Mara, the daughter of Đurađ Branković, despot of Serbia. His name appears on the treaty between Byzantium and Venice concluded in April 1448, in place of Demetrios Palaiologos Kantakouzenos, who was indisposed at the time.
