The name of Fulbert's wife was Isabel. In 8 Henry III (1223/4) the King informed the Abbo of Burgo that he had remitted the scutage of three knights' fees held by Isabel de Douvres in chief and she was to be quit thereof (Rot. Lit. Claus., vol. I, p. 583). She is one of the five daughters of William Briwere, who is known to have married Baldwin Wake, and Fulbert was her first husband.117

William Briwere married his daughter, Isabel, about 1200, to Fulbert de Douvres, by whom she had issue a daughter Roese. After the death of Fulbert, she was married to Baldwin Wake, who died before 21 July 1213, when her marriage was granted to her father William Briwere. Her heir was her son Hugh Wake, ancestor of the ancient Northamptonshire family of that name (V.C.H. "Northamptonshire Families Wake", compiled by Oswald Barron, Table, pp. 337-339; Dugdale's Baronage, vol. I, pp. 539/40).117

Weis' "Ancestral Roots. . ." (184A:7), identifies her as an eventual coheiress of her father, as the widow of Fulbert of Dover, as the wife of Baldwin Wake, and the mother of Hugh Wake.
