[1] Francesco inherited the title of Count of Geraci from his father, Enrico II.
Francesco served king Frederick III of Sicily as ambassador to the papal court in Avignon.
Francesco's son, called Franceschello, and his secretary, on a mission to the King's court in Palermo, were imprisoned and the secretary was tortured to confess that Francesco and Frederick of Antioch were complicit in a plot against King Peter.
[2] The King and his allies forces, including the Chiaramonte, besieged the castle of Geraci, to which Ventimiglia had retired.
The facts of his death are unclear, but legend holds he attempted to flee with his weapon and either fell down a cliff or was stabbed (or both) by Francesco di Valguernera, Lord of Godrano.
