“ His chief dwelling and place of residence was at Jutsworth, near Saltash and Trematon, where he married and had issue one only daughter named Agnes, as some say, others Beatrix, who was married to Reginald Fitz-Harry, base son of King Henry I., by his concubine Anne Corbett, in whose right he was made Earl of Cornwall, after William Earl of Cornwall aforesaid had forfeited the same, by attainder of treason against the Conqueror and his sons, and was deprived thereof. ”
