|William Fitz-Osbern (11th century)||William Fitz-Osbern was born in Poitiers cir. 1020/1030, the illegitimate son of Osbern Sieward of Normandy (Osbern the Seneschal) and brother of Osbern (later Bishop of Exeter). He married Adeline, sister of Ralph de Tosny. He assisted William the Conqueuer by leading the right wing of the forces at the Battle of Hastings, defeating King Harold at The Battle of Hastings (14 Oct 1066). After King William I's coronation (25th Dec 1066), he claimed all the land in England and distributed the land between himself and those men who had helped him at the Battle of Hastings. King William installed William Fitz-Osbern as one of the few leading Norman landowners and was given vast estates, notably in the Welsh Marshes and the Isle of Wight (Osborne House?) - together with the titles 1st Earl of Hereford in 1067 and Lord of Breteuil (in ?). While King William was away (1067), disturbances broke out in Kent, Herefordshire, and in the north of the country and Fitz Osbern played a leading role in putting down these rebellions. To maintain control over his own land Fitz Osbern built several castles including Carisbrooke on the Isle of Wight and then in South Wales Chepstow (Striguil), Wigmore, Clifford Castle and Monmouth, as well as creating or improving the fortifications of the towns of Hereford and Shrewsbury. William Fitz Osbern was killed in Bavinchove, near Cassel, Ravenchoven in Flanders on 20-22/02/1071. The death-blow dealt by one of his own knights, named Gerbodon, who had previously unhorsed him, but we are left in doubt as to the motive of the felon. The Earl's body was carried by his men-at-arms to the Abbey of Cormeilles, in Normandy and buried there "amid much sorrow". His son Roger Fitz-Osbern inherited his title and estates, led an uprising against the King (1075), was quickly suppressed - and forfeited his estates and imprisoned for life. Ordericus Vitalis, the norman chronicler wrote in 1141 of the family being lost without trace "Truly the world's glory droops and withers like the flowers of grass; it is spent and scattered like smoke".|
