According to Martha Winstead's book Mandley Winstead m.Elizabeth Cox Their son Alexander T. Winstead m.Priscilla AnnTice Their daughter Elizabeth T. Winstead m. Mandley William Winstead I do not find another Alexander listed with either Alexander T. & Priscilla or with Elizabeth T. & Mandley William Winstead.
Alexander T. Winstead had a brother named Bushard Dabney Winstead who married a Susannah W.Cox. They had a son named Alexander b. 1818 KY. There may be a mix up here by one being the guardian of another relative's children as there is not a son named Pleasant with either listed. Hope this is of some help. Correze@webtv.net
