In 1404, together with his two sons Brunoro and Antonio II, he led a revolt against the Milanese. He was proclaimed Lord of Verona on 17 April, but was expelled from the city by the populace on 28 April. Francesco da Carrara, Lord of Padua, took over the city a few days later.

By his marriage to Onesta Mortone, Guglielmo left the two aforementioned sons, who never regained power in Verona, and three younger sons: Bartolomeo (died 21 March 1453), Fregnano (died 4 December 1443 at Vienna), Nicodemus, and Paul.
