I am looking for ancestors of Christine Schleuter and Mark Kohnke. They are my paternal greatgrandparents. Mark Kohnke born Jan 4, 1847 in Borkholt SH Came to America from Hamburg on the ship Holsatia in 1869 He was in America a few years and then went back to Germany In 1879 he came back to America again on the ship Herder with Christine Schleuter born Nov 27, 1860 in SH They were married in MN and had 9 daughters and 1 son They also lived in ND and SD where they both died. I believe that Christine Schleuter Kohnke was somehow related to a Rosa Pohlmann. Rosa Pohlmann sent letters and pictures to some of Christines daughters in 1947. Rosa Pohlmann may still be alive or perhaps her children Elke or Reimer are. I believe Rosa's address at that time was Knoll Wulfsmoon Kellinghusen Holstein Br Zone Germany. Can anyone help me with any information on any of these families. Any help would be greatly appreciated. Robbie
