William was one of the few barons who remained loyal to King John (who was his cousin) during the king's difficulties with the barons, when they sought for the French prince to assume the English throne, and is listed as one of those who advised John to accede to the Magna Carta. His allegiance only faltered a few times when the king's cause looked hopeless.
