I see that 2 of your Bickelhaupts were in Illinois. Could they be related to George Bickelhaupt, husband of my greataunt Lillie Menke and father of her older child Frieda Walz. these were all Quincy Il people.. I saw the names of George and Frieda on a headstone at the cemetary some years ago, but it took me a long time to find the connection because they seemed to be buried in the Menke section where I had been looking for my Menke ancestors. Now I know why they were there. Did all these Bickelhaupts come from the same place in Europe? Were they Catholic or Protestant? thanks for any help
