I have found an ancestor that was in Madison Co. also listed in Garrard Co at another time. Since parts of Garrard were in Madison at one time, I'm having to look deeper at land transactions to see if they were actually in one place all the time. Perhaps the same thing could have happened with your family, the family stayed put, but the county moved. :-) There are websites out there that show the progression of the counties over time. I can't find my link to it at the moment or I'd include it here. Denice
