Osbern de Crépon

Osbern de Crépon († towards 1040), was the Sénéchal of two dukes of Normandy.

Biography

He was the son of Herfast, and the nephew of Gunnor, the second wife of Richard I {{er}} of Normandy (marriage “ More danico ”). Its appearance in the acts of the duke of Normandy goes up at the end of the reign of Richard II (years 1020). Under Robert Splendid the (1027-1035), it occupies the function of Sénéchal. Function which it preserves after the death of the duke in 1035. It then becomes one of the legal guards of the young successor Guillaume Bastard the (later the Conqueror) 8 years old. The young duke is in danger, the Richardides seeking to assassinate it to take again the capacity on the Norman duchy, and barons rebelling.

Osbern is assassinated about 1040 by protecting the duke. According to Guillaume de Jumièges, he is strangled by Guillaume, sons of Roger I {{er}} of Montgommery, with the Vaudreuil in the first years of the reign of the duke. Barnon de Glos avenges death for its lord by assassinating the murderer.

Historians of the duchy are opposed on the origin of the goods held by Osbern. Did they come mainly from his/her father Herfast or its marriage with Emma, girl of powerful the Raoul d' Ivry, or of Hugues of Bayeux? In any case, it was possessioné in very dispersed areas of Normandy: in Bessin (Seersucker), in Hiémois (close to Cliff), on the level of the confluence the Seine - Andelle, around Cormeilles, in the Talou, in Country of Ouche (Breteuil-on-Iton, the New-Quadrant).

Family and descent

He married Emma d' Ivry, girl of the count Raoul. They had three known children :

Guillaume Fitz Osbern (about 1020 - 1071), 1st Count d' Hereford ;
