Hi all., �I have something that I need clarified.� The Federal census was taken every ten� years since 1790?� It is only in public record until 1910? or 20?� Also , one year, I think 1890 is missing.� Am I right so far?� States and counties sometimes took their own census also.� If I found a census online that said say, Fairfield Co. Oh census for 1880, would it be safe to assume that it came from a federal census? I have found quite a few of these but they don't say whether it was a federal census or not and I am new at this.� How do I tell? LeaAnn
