Hello, my name is Peter Dohr and my great grandfather was Fred Dohr. I was delighted to read this post regarding the Dohr family as I hit a roadblock at Johann Dohr. In my grandfather's autobiography he says both his father (Johann) and mother (Justine) were born and raised in the village of Zelgniewo. With this in mind, I do believe it's safe to say Christoph Dorre and Rosina Kewit were Johann's parents. Mr. Neumann, you said you saw some type of film regarding the Dohr family? I would be ecstatic to learn more and be able to go back further into the 19th century if it's at all possible. Or to even find out if there are any Dohr's left who are part of this tree. The only one I know of lives in San Diego and is descended from Chritoph Doehr (Johann's brother). It's been over a good two years or so since I last did any work on this. Is anyone on this thread connected to the Dohr family?
