Nancy unknown was listed on the 1850 census as being born in GA in 1803/04. Nancy Germany was married to John McCraine in 1828.(McRaine/McCraney) Will of Murdock McCraney proves the children of John and Nancy McCraine in Wilkinson County, MS. Their marriage bond was also signed by William Varnell.
Although it is very possible that she was married prior, because of her age, the census (1840 or 1850) does not suggest any children before her marriage to John McCraine. The Varnells were in SC .....do you know where your Nancy was in 1827/1828?
