This family history begins with Hugo le Corbet or le Corbeau. With two of his sons, Roger and Robert, Sir Hugo joined in the battle of Hastings with William the Conqueror in 1066. Hugo helped counsel the Conqueror in regards to the Welsh border lands which were rebellious. For their service as knights to the Conqueror, Robert and Roger were given Baronies. Roger received twenty-five manors. Robert received a grant of fifteen manors in Shropshire which became the barony of Longden. These Manors were townships under the Saxon rule. Roger called both his castle and barony "Caus" after his home in Normandy. The Corbets served under the Earl Roger de Montgomery. They were in service to help control the borders of Wales. -----Corbet Genealogy Ring
Roger Corbett's Shropshire Land Holdings in Domesday 1086
Corbet and FitzCorbet, a Norman family from Pays de Caux claims ancient Viking origin from the original settlers in Normandy under Rollo, the first Duke of Normandy. The father, called Le Normand, or simply Norman, had four sons, Hugue(Hugh/Hugo), Roger, Reynaud and Robert. Hugh and Reynaud stayed in Normandy in the senior family domains. The family adopted the surname Moreton in Normandy. The father, and sons Roger and Robert, were at the Battle of Hastings. Between them, they were granted 38 lordships in Shropshire where they assisted Earl Roger in the administration of his domains in that county. Roger Corbet built a border fortress at his Castle at Alfreton which he named Caux Castle after his home domain in Normandy. It was later spelt Cause. The holdings in Derbyshire of the father, called Norman, Roger the second eldest son and Robert the youngest son, both sons sometimes listed as FitzCorbet, are listed together as family domains. They were under-tenants of Earl Roger in Shropshire.
