D'Oyly and Barry Families

Any authentic information, original or not in the usual depositories, concerning the two great Norman races of D'OYLY and BARRY, or De Barry (both of which settled in England at the Conquest, and, singularly, both connected themselves with mistresses of King Henry I.), will be thankfully received if sent to WM. D'OYLY BAYLEY (Barry), F.S.A., whose histories of both races are still unfinished.
