Sylvia, I just re-read your second post and you listed that your John Smitherman had a sister listed in his household in the 1880 census. Would you please send me back that census entry. From what I can tell from your email her name was Rebecca and she was born 1838? If this is correct would you please check and she is she is listed as a sister or if was actually sister-in-law. From what I know about the Smitherman family if John's wife Mary who was originally listed on the marriage license as Smitherman and then Smitherman scratched out and Latham written above it,and she was indeed actually Mary Latham then I can help some. Keziah Smitherman Latham did indeed have a daughter named Mary Latham and a daughter named Rebecca Latham. If the census shows a Rebecca Smitherman as being sister-in-law then they are indeed Keziah's daughters. I may then need to get you to check and see if there are any VanBuren's listed in the area.
