His son was William the Noble, whom all the Scots wished to take for their King' (Coll. de Rebus Alban., p. 346). In 1179 King William the Lion had some trouble with a revolt of the men of Ross and Moray under a claimant who (Fordun says) 'pretended to be the son of William the son of Duncan the Bastard.").
