Étienne le Gros
From Wikipedia, the free encyclopedia
Stephen le Gros[1] was the second son of Stephen of Aumale.[2] He married his cousin, the eldest daughter of Roger de Mortimer, his mother's nephew.[3] By her they had one son, William Crassus or 'le Gros'.[4]
It was in all probability from this marriage that William Crassus (or le Gros), the kinsman and follower of the elder William Marshal, Earl of Pembroke, sprung.
