We are descended from the Prussian line Friederike Luking married Johann Christoph Niemann. She was the daughter of Johann Hachmeister and Anna Dingerdissen. Friederike and Johann fled Prussia to the U.S. during Otto vin Bismark’s Persecution of the Socialist Democratic Party. Johann Christoph Niemann was the son of Franz Niemann and Anna Katerina Kaiser zu Dingerdissen. There is a lot of crossing back and forth with surnames between the Niemann and Luking lines and from what I’m understanding that may be because some of those possibly refer to a place they are from not a proper surname?
