Marie, I agree that listing a birth county can be tricky. I think that it is possible that someone born in a particular town or city passes that information along to descendants. When a family member looks (maybe a century or two later) for that place on a map and determines the county, he or she may be unaware that county boundaries changed and sometimes changed dramatically. That could be true in PA and definitely is true in states like KY. I see the same VA marriage listed in multiple counties. It takes some backtracking to figure out what the original county was. Sometimes even the state changes. I have one in-law who gave his birthplace as Knox Co. NC. I think it might now be TN, but I do not know for sure. I also agree with you that there is no proof of place listed--not even the state as far as I can tell. I am amazed that you can remember as much of the county changes as you do. I always have to look it up. This is not my family, but if I get some time, I will see if I can puzzle anything out. Sherry
