He first appears in a document of 1059, when he is placed in power over the city of Savona, probably as per a request of the citizenry for a ruler of their own.

He was present when the Emperor Henry IV donated the monastery of Breme to the church of Pavia.

In an act dated 15 September 1096, Uvilielmus, the son of the late Uviliel and Ota, the daughter of the late Tebald, and Uvilielmus, the son of the aforementioned Uviliel and Ote, and Oto, the son of Oton, or Peter, the son of Robert, and his spouse Ermengarda, the daughter of the aforesaid Tebald and Tezo, the son of the aforesaid Petri and Ermengarde conceded their rights over the church of Santo Stefano di Allein.

By his second marriage with Otta di Aglié, William was the father of his successor Rainier. He had two children by his first marriage, but their fate is unknown.
