I have found Lucy Caldwell living with her daughter and husband, Nancy and Joseph Gilbert, in Kewanee, IL in 1860 census. She has filed papers at the Henry County, IL courthouse stating that her late husband, John Caldwell, was a veteran of the American Revolution. Since she was in her 70's at this time, I feel she was probably much younger than John and probably a second wife. They would be my great-great-great grandparents. Any information would be greatly appreciated.
