William was a son of John Marshal and his wife, Hawise de Say. When his father died in 1282, John de Bohun, a younger son of Humphrey de Bohun, 2nd Earl of Hereford, acquired from King Edward I the guardianship of young William (at the time a minor) and the right to administer his estates, for 2500 marks. He was a signatory of the Baron's Letter to Pope Boniface VIII in 1301. In 1308, after taking part to the coronation of King Edward II, William attempted, as a member of the Marshal family, to claim the office of Lord Marshal of England, but he was unsuccessful. On 8 December 1309, however, he was admitted to parliament as “Baron Marshal”. In 1314 he took part in Edward II's campaign against Scotland, where he died.

He was a great-great-great grandson of John Marshal, brother of William Marshal, through an illegitimate son of John.
