William of Hauteville (c. 1027 – 1080) is one of the younger sons of Tancred of Hauteville by his second wife Fressenda.
He is usually called Willermus instead of Wilelmus in Latin annals and so is often called Guillerm instead of Guillaume in French.
He leaves Normandy around 1053 with his elder half-brother Geoffrey and full brother Mauger.
