Fiorello Beccaria
Fiorello Beccaria was a nobleman of Pavia, the younger son of the signore Musso Beccaria, and shared rule over the city with his brother Castellino. He married Filippina Sannazzaro and rebuilt the fortress of Rocca de' Giorgi, later called Roccafirella after him.
He founded the Beccaria di Messer Fiorello line; his son Galvagno received the fief of Pietra in 1405, and his descendants ruled there and held Castana castle until 1531.
