Hello, I have recently visited this region of Germany and I believe I have found my surname's origin. I am researching the names posted in the subject. I found those names in Lasserg (Lasserk), Munstermaifeld and Wierschem. Any knowledge of the those names would be an inspiration to me in my research. Especially the name Dunchem. Barbara Dunchem married to Joseph Haendgen and had a son Joseph Haendgen in 1819, who was, we believe, my g-g-g-grandfather. Thank you, Kim Handgen Sandstrom
