I don't know anything about her, but, just for fun, I looked up Aaron McKin in the censuses for 1880, 1910, and 1920. In 1880 Aaron was age 5, living with his family (James and Sarah J. McKeen) in Cherokee County Alabama, Township 7, page 259A. In 1910 Aaron, age 35, was married to Carrie, age 36. They had been married 3 years. It was the second marriage for him and the first for her. She had given birth to two children, both of whom were living. They were: James 2, and Justin 10 months. They can be found in Georgia, Walker County, Peavine twp, page 159. In 1920, Aaron was listed in Georgia, Walker Co., Chestnut Flat, 869 Militia Dist., E.D. 174, page 4A. I can't find Aaron in the 1900 census, but a good guess would be to look in Cherokee County Alabama. Also, I would suggest checking the marriages for Cherokee County Alabama to see if you can find a marriage record for him and his first wife. Hope this helps.
