Robert left Orkney and went to Normandy. Apparently he accompanied William the Conqueror to England, for the
Encyclopaedia Britannica (1956, 4:280) states: "The first Robert de Brus, a follower of William the Conqueror, was
rewarded by the gift of many manors, chiefly in Yorkshire, of which Skelton was the principal." "The Bruce Journal," Vol.
1, No. 4, p. 47, credits him with building the castle of la Brusse in Normandy at Brix.
