Can anyone tell me how to get information on my great-great-grandfather's family in Dettweiler, Germany. He was Peter Diesz or Dies and was born 6-28-1809 in Dettweiler, emigrated to Philadelphia in 1838, married Frances Steiner and moved to Ohio in 1840. Perhaps a Catholic Church in Dettweiler would have this information. I'm at a deadend with Peter.
