We welcome any person who believes they may be related to the surname Diteman or variant spelling, to test with FTDNA. Our goal is to connect and exclude variant lines, so that the questions we have all had for many years will be answered. Should your YDNA not match, we would kindly encourage you to start and administer your own surname project with FTDNA, and encourage others to test with FTDNA as well, for matches and exclusions. Good luck to all who search. Thank you very much.
