Robert de Conteville, comte de Mortain
His parents were Herluin , Vice Count of Conteville (1001-1066) and his wife Herleva (Arlette) (1003-1050). Through his mother he was the half-brother of William the Conqueror (1027-1087) and brother of Odo , Bishop of Bayeux (1035-1097).
In 1049 his half-brother Wilhelm appointed him as Count von Mortain , as the successor to his second-degree uncle Wilhelm Warlong, who was deposed in 1048.
He accompanied his half-brother in the conquest of England and took part in the Battle of Hastings (1066). In return he received from his half-brother William, now King of England, several English lands as fiefs and in 1068 the title of Earl of Cornwall . This made him one of the largest and most powerful landowners in England and Normandy .
In Mortain he had the predecessor of today's collegiate church of St. Évroult built, of which a portal from his time has been preserved. His chaplain was Vitalis, who was later canonized and the founder of Savigny Abbey . After his death he was buried in the Notre-Dame Abbey in Grestain .
