From "Katherine Talbot, wife of Ralph Parles, and her daughter, Margery Parles, wife of John Hervey and William Argentine" - message posted May 2008 - Douglas Richardson writes:

.... Thus, it would appear that Ralph Parles first wife was Katherine Talbot, not Joan Talbot, she being a daughter of John Talbot, Knt., of Richard's Castle, Herefordshire, by his wife, Juliane, daughter of Roger de Grey, Knt., 1st Lord Grey of Ruthin. Katherine Talbot's mother's descent from Geoffrey Plantagenet can be found in my book, Plantagenet Ancestry (2004).

Ralph Parles, Esq., and his wife, Katherine Talbot, had one daughter, Margery Parles, who married (1st) John Hervey, Esq., of Thurleigh, Bedfordshire, and (2nd) William Argentine, Knt., of Halesworth, Suffolk and Great Wymondley, Hertfordshire. Margery Parles had four known children by her Hervey marriage, but none by her Argentine marriage. There are many modern descendants of the Hervey marriage. ...
