carolyn - i have not done a lot of work on this line, but the children of Jesse and Mary Ann Whitehorn included Susan, Harriet J., Benjamin F., Eugenia (June)W., Mary, John A.H., and Josephine.I am sure you must have more to add to this.
Mary Ann's brother, James L. Whitehorn, could very well be the james whitehorn of jonesboro, washington co., tenn.While not proven, there is a case for it.My notes on James:
1810 census:appears statistically as one of two males and one female under 10 (1800-1810) (James, Mary Ann, and Joseph) in the household of philemon and susanna whitehorn at sussex co., va. 1812:james' father, philemon, dies at Sussex Co., Va. 1815:james' widowed mother remarries to Bennett Barnes at Sussex Co., Va. 1820 census:James disappears statistically from the household of bennit barnes at sussex co., va.this household now records two males under 10 (1810-1820) and one female 10-16 (1804-1810).This record accounts for Mary Ann, but James and Joseph are both missing.Two new males are added to the family. 1827:sister Mary Ann marries Jesse Whitehorn in December. 1830 census:all three of the whitehorn children are statistically absent from the household of bennett barnes at greensville co., va.replaced by two males 10-15 (1815-1820). 1830:James Whitehorn sells land in sussex co. to Joseph Whitehorn (his brother?) 6 nov 1830 (sussex co. deeds) 1832:James Whitehorn marries Rebecca Ann Underwood at Sussex Co., Va. (SUSSEX CO. MARRIAGES, 1754-1850;). 1840 census:James disappears from Sussex County, he could be the james of jonesboro, washington co., tennessee who was married to a woman older than the one he was married to in 1850. 1840's:Rebecca, perhaps, dies and James remarries a younger woman, Martha Foster?? 1850 census:could be the james of jonesboro who is married to martha foster.
