Niemanns from Bahnsen, Hanover, Germany
Am looking for Niemanns that originated from Bahnsen, Hanover, Germany. My great-great grandfather, Carrten Christoph Niemann came over with his sister, Dorothea in about 1865 to Thornton, Illinois. Christoph's children were Heinrich, Louis, and Dorothea, maybe others. Does anyone have further information of this line.
