Roger de Mortimer, seigneur of Mortemer-sur-Eaulne, whose ancestry is unknown (or not traced here), died before 1086.1

Roger married Hawise, whose ancestry is unknown (or not traced here).1

Roger was one of the leaders of the Norman forces at the battle of Mortemer in 1054, but having assisted the. escape of one of the French prisoners, Ralph, Count of Montdidier, to whom he had done homage, he was exiled and his lands confiscated. He was afterwards reconciled to Duke William and some of his lands were restored to him, though not Mortemer, which had been given to his consanguineus William de Warenne; Saint-Victor-en-Caux thereupon became the caput of the Norman honour of the family.

He is said to have founded the abbey of Saint-Victor-en-Caux. He was living in 1078 or later, but was dead in 1086, when his son Ralph appears in Domesday Book.
