Please look on my german homepage for this town, maybe some of your ancestors come from. Here lives a famous family (named Friedenthal) on a Rittergut (manor, named Friedenthal), later the small town nearby is named Friedenthal-Giesmannsdorf (before: only Giesmannsdorf). Karl Rudolf Friedenthal was Landwirtschaftsminister, Secretary of Agriculture.
