Research Notes:
issue of Isabel de Ferrers had certainly failed by Apr 1327, when an inquisition was taken after the death of John Meriet, who had married her granddaughter. Either Margaret was the daughter of another wife of Edmund Deincourt, or Edmund's wife Isabel was not hte daughter of Isabel de Ferrers [Ref: CP++(proposed) Willoughby 12/31/2006 (CP XII/2 p658)]
