Robert de Brus, 1st Lord of Annandale

Robert de Brus (c. 1078–1141), first Lord of Annandale, was a Norman knight from Brix who came to England with King Henry I and founded Gisborough Priory in 1119.

His friendship with David I brought him the lordship of Annandale in 1124, but when David invaded England in support of Empress Matilda, Robert renounced his homage and fought for Stephen at the Battle of the Standard in 1138. He died in 1141, founder of the Bruce dynasty in Scotland.
