Person:Margaret Stafford (10)

Foster, cited above, lists Margaret de Stafford as the daughter of Ralph de Stafford and his second wife, Margaret de Audley as opposed to the ancestry listed here which has her as the daughter of his first wife, Katherine de Hastang, which is supported by the Ralph de Stafford, 1st Earl of Stafford Wikipedia article and the Dictionary of National Biography.
