Guglielmo II da Verona
Guglielmo II da Verona (died 1273/75) was a Lombard noble of Negroponte, the second son of Guglielmo I da Verona, triarch of the central third of Euboea. He married Catherine, a niece of Prince William II of Villehardouin, with whom he had no known children.
He joined the Latin lords' naval attack on the Byzantine fleet anchored at Demetrias: after an initial Lombard success, the despot John Palaiologos arrived through the night with reinforcements and routed the Latin fleet. Guglielmo was killed in the battle, while the Venetian commander Filippo Sanudo was captured.
