Carlo I Tocco
Nerio fathered two legitimate daughters, Bartolomea and Francesca. He gave Bartolomea in marriage to Theodore I Palaiologos, Despot of Morea, and married off Francesca to Carlo I Tocco, Count Palatine of Cephalonia and Zakynthos. Francesca was sent to Euboea (or Negroponte) as hostage to guarantee Nerio's support for Venice against Theodore I Palaiologos in 1390. Stathakopoulos proposes that Antonio may have replaced Francesca as hostage, but he was released in less than 18 months. King Ladislaus of Naples granted the Duchy of Athens to Nerio and his legitimate male heirs on 11 January 1394.
