My GGGgrandfather is Ferdinand Reetz. He was born in Kolmar, Poznan, Prussia on 14 May 1841. His siblings are Christoph, Gustav & Paulina. They were born to Anna Justine Koepp (b. 1812)and Christoph Reetz (b. 1804). Christoph senior died in 1851 in Prussia. Anna Justine re-married and immigrated to Neshkoro, Wisconsin, USA with the children and her new husband August Prachel.

I am looking for further information on the parents of both Christoph and Anna Justine. I have found possible information on their marriage on the Poznan Project website, however Christoph is listed as "Gottlieb Christoph Reetz." Parent for Christoph is listed as Michael (father) and parent listed for Anna Justine is Georg (father).

Any additional information would be appreciated.
