Concerning Sarah Drucilla Byars, you might want to take a look at the book: BYARS FAMILY HISTORY by Nell Byars Thaten. Six listings are shown for individuals named Sarah Byars. Do not know if any of those individuals so listed are the person of interest. The book in question traces the migration of a branch of the Byars family from Virginia, through the Carolinas, Georgia, Alabama, Mississippi, to Texas. Got a copy of the book through interlibrary loan and copied parts of interest to me plus the Byars portion of the index. My branch split away from that group in early Virginia and headed to Washington Co., VA. Herb Cunningham
