Was there not other census taken other than every ten years. Perhaps a County census or such? I have been looking so hard for the whereabouts of my g.g.grandparents Johan and Anna Johnson/Johansson. I have seen them as early as 1877 on the tax rolls for Deerfield, but cannot get back further than that. They came to Cook County Illinois in 1868 I believe, but cannot find them so thought perhaps they were in Lake county instead of Cook county. Any help would be so appreciated! Thank you, Brenda G.
