Richard D' Avranches, a companion of William the Conqueror at the Battle of Hastings, son of Toustien le Goz and Judith de Montanolier,was born about 1025 in Avranches, Normandy, France. He died in 1066. He married Emma de Conteville. Richard Goz, Vicomte d'Avranches, or more properly of the Avranchin, was one of the sons of Turstain [sic], by his wife Judith de Montanolier, and appears not only to have avoided being implicated in the rebellion of his father, but obtained his pardon and restoration to the Vicomté of the Hiemois, to which at his death he succeeded, and to have strengthened his position at court by securing the hand of Emma de Conteville, one of the daughters of Herluin and Herleve, and half-sister of his sovereign. By this fortunate marriage he naturally recovered the lands forfeited by his father and bestowed on his mother-in-law, and acquired also much property in the Avranchin, of which he obtained the Vicomté, in addition to that of the Hiemois.
