My great-great-grandfather Gustav Ernst Kropp was born 12th May 1840 in Rheydt Germany. His father was Johann Peter Kropp and his father Peter August Kropp. Is here anybody who can tell me more about my Kropp ancestors? More information about these persons can be found on my website http://familie-zimmermann.de/Familien_H-O/Kropp/kropp.html where you can find my contact details.
