I found a Mahetabel Harrell wife of Eli White, died May 3 1889, aged 74yrs 6 months and 11 days.
Eli White died May 6 1888 aged 80 years 10 months and 2 days.
Both buried in the 8th Ward East Feliciana in what is listed as the Jackson-White Cemetery.
This is around the Beaver Creek area you have talked about. I realize the last names are a little different than in your previous reply.
I have a book from 1970 by Mary Ann Smith Sagely of all the cemetery inscriptions of East Feliciana Parish at that time.
John White b.18 Feb 1780 in SC d. 9 Apr 1843 husband of Lydia Morgan are also buried in this same cemetery.
Please let me know if you would like more info or if this helps.
