My Gerhard Kuhlmann was married in StL. in 1850. He was also from Kingdom of Hanover, believe near Osnabrueck. His father was Johann Frederich. I have just hired a German researcher and if there is anything connected to you I will let you know.Supposedly 5 brothers came to StL. These Kuhlmans were land owners (as the story goes) who had their land taken away by the Prussians. And they did use the von in Germany. Marcia Kuhlman Cray, Quincy, Il.
