Roger of Mortemer

Roger I of Mortemer (Roger de Mortemer, Roger de Mortimer, Roger Mortimer) (fl. 1054 - aft. 1078), founded the abbey of St. Victor en Caux in the Pays de Caux of Upper Normandy as early as 1074 CE. Roger claimed the castle of Wigmore, Herefordshire that was built by William FitzOsbern, 1st Earl of Hereford. This castle became the chief barony of Roger's descendants. He was the first Norman ancestor to assume the name Mortimer, as in the place-name Mortemer-en-Brai, the land on which the village and castle was located.
