Guglielmo I of Ceva

Guglielmo I of Ceva (before 1170–before 1222) was the first marquess of Ceva and founder of the Ceva line of the Aleramici, son of Anselmo and grandson of Bonifacio del Vasto; his brother Bonifacio founded the Clavesana branch. In 1188 he swore the cittadinatico oath at Savona.

In 1190 Asti forced him to surrender Montezemolo and Murialdo, returned as fiefs, and in 1191 he was podestà of Asti. He died before 1222, succeeded by his sons under Guglielmo II.
