My great-grandmother was Ida Belle Allen b: 29 Dec 1871 d: 25 Aug 1965. She was born in Whitehall, Greene County, ILHer parents were Gregory Farmer Allen b: 12 Feb 1838 d: 31 Jan 1892. He was born in Whitehall, Greene County, IL. His wife was Sarah Elizabeth Buck b: 28 Feb 1846 d: 9 mar 1918. His father was Nathan Allen b: 30 Mar 1799 d: 8 Apr 1878. His wife was Teletha Doyle b: 9 Jun 1801 d: 7 Jun 1873. I believe they are both buried in Wilmington Cemetery, Patterson, Greene County, IL. (I could be wrong about the name of the cemetery). I have seen two different sets of parents for Nathan Allen. Thomas Allen b: 1766 in North Carlorina d: 7 Sep 1832 in Greene County, IL and his wife Margery Bryan. Then I also have seen Nathan's parents listed as James Allen b: abt 1760, his wife Nancy Cannaday. James's father is Zachariah Allen and James had brothers named Zachariah and Thomas.I've seen where Thomas (wife Margery Bryan)and James (wife Nancy Cannaday) have the same set of children listed in other people's family trees. I haven't verified which set of parents belong to Nathan. There is a book called History of Greene County, IL 1879 that I would like to look at for some verification. Maybe this helped you a little. Let me know if I can be of any other help.
