Hopefully, this won't be too ignorant. I have 2 questions: Is their a site to go to that you can type in a surname and it will tell you what counties to check the census for? If I've already checked the county I think they lived in with no luck, I'm hoping not to check every county!! Also, just found my grandfather's occupation listed as "Supervision of Materials, Knox County" during the late 1930's. Any ideas what that could mean? Thanks. Teri
