My great grandfather, Paul Bensch, was born in Kosendau and lived in Jauer Germany. He left for the U.S. in 1929. When he returned to Germany in 1933, his entire family was gone. I'm looking for Bensches that may have fled that area. Vrchlabi and Horni Upa are somewhat near Kosendau/Jauer, so I'm wondering if my relatives fled there. Any thoughts or information?
