While reviewing FHL microfilm #99037 Schwarzach, I found the surname Klopfer in the Register of Moos. This register I think covered the years 1682-1727. Moos is in the Black Forest region near the Rhein River.
Other surnames in Moos include: Haungs, Burkhardt, Berger, Ernst, Friedmann, Oser, Ruschmann, Hensel, Winter, Ochs, Noldner and Seiler.
My Moos immigrant KNAB family left Germany in 1831 to the Buffalo NY area. The Knab family ancestral line is from nearby Unzhurst. We used FHL 1045112 to trace our line.
