carolyn - i cannot strongly defend James Whitehorn as a son of Philemon and Susanna.I can only try to reconcile the presence of a james whitehorn at washington county, tenn. after the apparent departure of a james from Sussex County.Also, there was a second son from Philemon Whitehorn in addition to Mary Ann and Joseph, on the 1810 census who is not accounted for in the guardianship papers.Further, James Whitehorn of Washington Co., Tenn. is the same approximate age as the unaccounted for son of Philemon and Susanna.And, when james sold out in sussex county, he sold to Joseph whom we can strongly suspect was a son of Philemon and Susannah.
I don't know the date of the guardanship papers, it would be interesting to know, because it appears that Joseph and the second son are both unaccounted for on the 1820 census while Mary Ann is still in the household after Susanna's marriage to Bennett Barnes.
Of course, the unaccounted for second son might have died before 1820, or was warded off to another family which never established legal guardianship, or legal guardianship was granted to another family separately from the other two, maybe this record was lost, or maybe it was registered in another county.
James of Sussex County never appeared as a head of household in 1830, but he was old enough to own and sell land to Joseph in 1830.So, where was he in 1830?It would seem he was still in someone else's household.Also, as we know that Mary Ann married in 1827 and that Joseph married in 1834, we also know that James married Rebecca Underwood at Sussex County in 1832.This suggests that James, Joseph, and Mary Ann were of a similar age.However, by 1840 James is still not accounted for nor a widow Rebecca (there is a Rebecca who appears to be a childless spinster in 1850, 1860, and 1870, but she is the sister of Francis E. Whitehorn and daughter of William Whitehorn Sr. and Martha (Patsy) Whittington - unless, of course, whitehorn was her married name as well as her maiden name (this wouldn't be the first time that surnames intermarried!).
Finally, do you know where and when Susanna Simmons Whitehorn Barnes died?The reason I ask is that both she and Bennett seem to disappear from Sussex/Greensville after 1830.Do you know whether they sold their land in greensville?There is a Bennett Barnes and family who appears in Rutherford Co., Tenn in 1840. also, in 1840, there is a 50-60 yr old female in the household of James Whitehorn at Washington Co., Tenn.Could Susanna have spent her remaining years in Tennessee?
Finally, I would agree that Simmons Barnes seems a good bet for son of Bennett and Susanna.There should also have been a second son by Bennett, if you can believe the census taker.well, enough speculations, but I hope you can see why I think it is possible that James was the other son. -- tony
