I am looking for information on Friedrich Heinrich Hartung head of the German Shoemaker's Union in 1888 in Haderslev or Hadersleben Denmark. My Grandmother's parents are listed on her marriage registration in 1908 in Saskatchewan. She was Conradine Nissen born in 1887 in Hadersleben, her father was Friedrich Heinrich Hartung and her mother was Helene Nissen. Conradine travelled to America in 1907 on the Campania from Liverpool to New York according to Ellis Island records. She married Wilhelm Plohr who was also a passenger on this ship, he was from Suttorf Germany. Any information on her parents or siblings will be greatly appreciated.
