Becky, I have found this happens a lot. I also decided to just go through some of the census, page by page, looking for my ancestors and I would find them when Ancestory didn't even have them listed on ANY Census. So if you are really looking for someone, it is worth it, to just go page by page ,if you know the year and place. It takes a lot of time to do this, but if you find something it is a reward in itself. Tommye
