I'm looking for information on my great-great grandparents - Joseph Hopp (born Joseph Karl Robert Johann Hopp on June 8, 1878) son of Conrad Heinrich and Maria Eliesebeth and his wife Anna Eliza Walton (born April 18, 1882). Rumor has it, they are of German descent. They had nine children, 6 boys, 3 girls. The oldest daughter Julia was my great grandmother. Any information would be very helpful. Thank you.
