I am a little confused about your message.Did Randolph and Lydia SIMPSON have a son Jonathan who married Tabitha NIX and a daughter Elizabeth Jane who married Lewis ALLEN?
I have Anguish ALEXANDER's son Jesse (b. 1720)m. Mary (b. Union, SC). Their son was Randolph (b. c1748 d. 10 Aug 1789/1798) m. Lydia SIMPSON (b. c1750 d. aft. 1790).The children of Randolph and Lydia are: Angus (b. 16 Oct/10 Aug 1778 d. 4 Feb 1855), Jesse (b. 1788 d. Nov 1870) Simpson B. (b. 1795).
I'd love to learn more about this family but I think I have the generation confused somewhat.I can't find Elizabeth Jane at all.
