On the 1900 census James has in his household a Sarah Wood, 61, b AL, wid, and she is listed as "aunt."I find it interesting that the following AL family has both a Sarah and John P. with ages very close to a match, in the same household.It would make Sarah the mother.

The 1880 census does not ask questions about land, but on the 1870 Clay Co, AL census E.R. is Elijah and is a miller and owns land.You might check out land and probate records, see if you can find enough information to tell if the John P. in that family is your John P.
