Thanks for responding. This looks like excelent news. I got some respond on my search and I learned a little about my granduncle Theodore. But so far there was no news about him having children. In my family there was a strong believe that he had children because he wrote about them to my grandmother (Lemm). His Dutch relatives used to live in Holland very close to Germany, and some of them still do.
As soon as possible I'll mail you mare details about him, but I'm convicned we have a match. I'm very curious th know about the Lemm family over there.
Please from now on, use the mailadress above. the old mailadress will be out of order soon,
