It is generally accepted that Thomas had four children with Catherine Zaccaria. These four children were:   In the late 16th century, a family with the last name Paleologus, living in Pesaro in Italy, claimed descent from Thomas through a supposed third son, called John. This family later mainly lived in Cornwall and contained figures such as Theodore Paleologus, who worked as a soldier and hired assassin, and Ferdinand Paleologus, who retired in Barbados in the late 17th century. The existence of a son of Thomas called John cannot be proven with any certainty as no mention is made of a son by that name in contemporary records. It is possible that John was a real historical figure, possibly a illegitimate son of Thomas, or perhaps his grandson through of either of his known sons, Andreas or Manuel. Some later Italian genealogies dating to the 17th century and onwards give Thomas two more sons; a bastard son named Rogerio and a fourth legitimate son, also named Thomas. The existence of Rogerio and Thomas the Younger is overwhelmingly dismissed as fantasy in modern scholarship.
