There is a group in the familytreedna group dedicated to German DNA which I have joined using my brother's DNA, our surname is Kile, we are of German heritage and have hit a brick wall and would like to connect to others with similar DNA. We are not sure of the original spelling of the name so I am posting this to the message boards I think might be of help and want to include themselves in a study. If you have questions feel free to contact me.
