Foubert DE DOUVRES (a). [Complete Peerage XII/2:297-8, (transcribed by Dave Utzinger)]
(a) G. A. Moriarty, "The First House of De Douvres or De Chilham," in The New England Hist. and Geneal. Reg., vol cv, pp. 39-40. It was formerly believed that the family to which Foubert belonged took its name from Dover, but Round suggested that the name was derived from Douvres in the Bessin and the evidence which he adduced seems to be convincing.
