Geoffrey de Montbray
Born about 1030 - made Bishop of Coutances before 1066 - commemorated by street named 'Rue Geoffroi de Montbray' in that town - commanded a section of William the Conqueror's army at Battle of Hastings.
For various services to William he was granted some 280 English manors - life in England uneventful until 1088. That year William II (Rufus) faced most serious rebellion of his campaign -most of his father's supporters were against him - even Odo, Bishop of Bayeaux and half brother of William I.
Geoffrey and nephew Robert de Montbray side with Robert, other son of Conqueror - from Geoffrey's castle in Bristol the two marched on and burned Bath before ravishing county of Wiltshire - were finally repulsed at Ilchester. The rising collapsed - Geoffrey escaped punishment and lived quietly until his death in 1093.
