I received a note from Hans Roser who lives in Goldscheuer, Germany today. Marlen, Kittersburg and Goldscheuer are three small villages that connect to each other. The are located along the western border of Germany along the Rhine River, not far from Kehl. If you need help locating them on the map I will be glad to help out.
Hans has information regarding the Klem family and I have asked him to respond to our questions. I will ask him if I may post his e-mail address here.
