I really don't know anything about the Dotsons or Ashcrafts,but found the record you talked about on the LDS site. Thanks for the extra info & I will be on the lookout for more about them.I would think that if Samuel answered the census he would have told where he was born if you have an 1850 census.I think I would trust that.As to Sarah I have no idea where she is buried.Probably the last place John W. Mockbee & her show up on the census. At least you have validated for me they were married to each other & she is Jacob Ashcraft's child.John W. Mockbee died May 12,1903 at his son Walter's residence on Spruce St.in Terre Haute,Indiana. He was 76 yrs. old.The obitin the Evening Gazette newspaper said the remains were taken to Clay City for burial. Maybe Sarah is there too.Maybe you can tell by land records who Samuel decends from.I just started on this line & it will take me awhile to search.but I know from another line of mine that one can't always prove the parents unless a Bible record is left.I've heard that estray records might list a father & son.I think these records have something to do with farming.It's nice to find someone else kin to them.
