My great-great-grandparents were Jacob & Martha Vollmar who came over from Germany in 1867. They lived in Cedarburg, Wisconsin. I am looking for any information on Jacob & Martha as well as his kids. He had 10 sons all together with Louis J. Vollmer being my great-grandfather. He left Wisconsin and moved to South Dakota when he was a teenager. His brothers are: John, William, Christian, Ernst, Henry, Bernard, Fred (Friderich), he also raised a boy named Christ Neumeier as his own who also came over from Germany with them. 2 other sons died at sea. We spell our last name as Vollmer.
