Gilbert, Count of Brionne
|Gilbert, Count of Brionne|
|Noble family||de Clare|
|Father||Geoffrey, Count of Eu|
Gilbert was son of Geoffrey, Count of Eu (b. 962) who was an illegitimate child of Richard the Fearless. He inherited Brionne, becoming one of the most powerful landowners in Normandy. Gilbert was a generous benefactor to Bec Abbey founded by his former knight Herluin in 1031.
When Robert I died in 1035 his illegitimate son William inherited his father's title. Several leading aristocrats, including Gilbert of Brionne, Osbern the Seneschal and Alan of Brittany, became William's guardians.
A number of Norman barons including Ralph de Gacé would not accept an illegitimate son as their leader. In 1040 an attempt was made to kill William but the plot failed. Gilbert however was murdered while he was peaceably riding near Eschafour. It is believed two of his killers were Ralph of Wacy and Robert de Vitot. This appears to have been an act of vengeance for the wrongs inflicted upon the orphan children of Giroie by Gilbert., and it is not clear what Ralph de Gacé had to do in the business.[a] Fearing they might meet their father's fate, his sons Richard and his brother Baldwin were conveyed by their friends to the court of Baldwin, Count of Flanders.
