At first, because Grandpa told a WPA writer that Paul came from Austria, we looked for the wrong town in the wrong country. I thought Grandmas' parents came from Germany, and that my Janson grandparents did, too.
It turns out that really, only the Jansons, Nabers and Fuchs came from what we think of now as Germany. Sands came from Luxembourg, Heschs from the Czech Republic, and Otrembas from Poland.
