This website claims to have a lot of links for those searching German and Polish ancestors. Unfortunately, I don't speak or read either, so can't begin to evaluate their data. Perhaps those of you who are doing this type of research can pick out enough words to help them--that's what I do with the Norwegian records--learn enough words to figure out what I have found, and in the process, learn a few more new words!
