Marco de Bernardo Asen

Marco de Bernardo Asen was a son of Irene Asenina and the Venetian Paolo de Bernardo. By origin he belonged to the so-called gasmouloi — descendants of mixed marriages between Italians and Greek women.

Born probably around 1370–1375, he remained a Byzantine subject, unlike his father, who was a "civis Veneciarum." He is known from a document of 1395 in which he acknowledges a sum received and acts on the basis of a power of attorney from his mother Irene.
