Hi Gerry,
I don't have any data on the people mentioned below, but just tried to
figure out, from what part of Germany they came from. From the names of the
places, you mention (Treptow, Klein Teetzleben and Reinberg), I would guess,
that it is the area around the town now called Altentreptow. The link to
Google maps should show the area:
http://maps.google.de/maps?hl=de&tab=wl
Appr. 5 Km south of Altentreptow you find Klein Teetzleben and appr. 6 km
west of Altentreptow you find Reinberg. Alltough there are a number of other
Treptows and other Reinbergs in Germany and / or Poland (old German parts).
Maybe this helps a little?
Regards from Berlin
Walter
