I am searching for HILLMER and HILMER data. I found the wife of Hermann Friedrich Leopold RAUTENBERG 1789-1869 in Germany was married to Cathrine Marie THIES (1793-1872). Her parents are Johann Wilhelm THIES and Katharina Dorothee HILMER of Gerdau, Kreis Uelzen, Niedersachsen, Germany. I found this information and more in a German series called DEUTSCHES GESCHLECHTERBUCH ... Band (Vol)141, page 340. I found a WFT that had Herman but did not have any information on Catharine. Also, the dates for Adolph and his wife Mathilde Guelich seemed to be incorrect. I will try to contact them, but not sure they will respond.
Adolph Wilhelm Leopold RAUTENBERG and his wife Mathilde GUELICH are shown as emigrating to ?Syracusa? Wisconsin.
