I think its also worth looking for Francis in Arkansas as thats where he is in 1880. Meaning he had left Stoddard by this point yet again making me skeptical of the Phebe Marriage as that was in 1884 after Francis had already left Stoddard. Why would he have moved back?
That 1900 census with Jane F is the only one that says Francis Marion Davis was born in NC, isn't it? So if that is not your ancestor, then there is no reason to think he was born there, and you can pay less attention to those two possibilities I just posted - the family in Kentucky, and the Francis Marion Davis, 18, in NC.
I'm starting to realize that a lot of families in North Carolina thought that the general, Francis Marion, was a good guy.
The 1900 is the only census that mentions North Carolina yet again making me think its not my Francis.
The 3 census I do have all say Kentucky apart from the 1870 Census where he is listed as being born in Tennessee.
“Lets make a chart to show what details we have that have been noted on these census to help build a picture perhaps.
Francis Birth:
1860 Census: Born 1832 Born Kentucky
1870 Census: Born 1830 Born Tennessee
1880 Census: Born 1830 Born Kentucky
Going off this knowledge it seems likely he was probably born in 1830 and the 1860 census is just a couple years out for some reason. Should we try and search for any birth records in Tennessee for Francis/Franklin/F M Davis?”
