Hi, I have a Rosalie Kluck that had a child in 1867, so she was born early to mid 1800's. She married a Stephen Robeck. I am in Australia and I also have some other Klucks married into the Manthey family. The Kluck, Luck, Pomerenke, Robeck , Kruiske , Jeske and Manthey families who are all related to me are from the DeuthKrone West Prussia area where you mentioned. Allot of them all came out to Australia in the 1800's. not sure where this fits in with your research.
