RALPH DE GUADER  , earl of Norfolk (fl . 1070), was the son of a Norman who had held high positions in East Anglia, perhaps that of earl, in the reign of Edward the Confessor (c . 1055) . His son Ralph fought on the Norman side at Hastings, and was made earl of Norfolk by William the Conqueror . In 1075 the king's refusal to sanction his marriage with the sister of Roger, earl of Hereford, caused the two earls to revolt . They were easily defeated, though Ralph sent to Denmark for ships and went there himself to fetch them . Ralph forfeited his English lands, and took refuge in Brittany on his wife's estate . In 1076, having plotted against Duke Hoel of Brittany, he was besieged at Doi, and the Conqueror came to Hoel's aid; but Ralph finally made his peace . Both he and his wife took part in the first crusade (1099), and died on the road to Palestine .
