When I switched from FTM to Legacy in 2006, one thing I really liked was/is Legacy's potential problems list. It found A LOT of errors in my file that FTM didn't see. Most of them were simple data entry errors but they were errors none the less. It also knows when you enter a county that wasn't in existence when you are saying it was. For example, if I put that someone died in 1894 in Lamar County, MS it will give me an error message because Lamar wasn't formed until 1904. The newer versions of FTM may have the capabilities now, I don't know. Michele
