A farmer in the Waldviertel region of Austria is known to be a cousin of the German dictator. (To protect his privacy, the name of the cousin is never made public.)

The particular form of the DNA - Haplopgroup E1b1b (Y-DNA) - is rare in Germany and indeed western Europe. It is most commonly found in the Berbers of Morocco, in Algeria, Libya and Tunisia as well as among Ashkenazi and Sephardic Jews.

39 other distant relatives of Hitler have been identified but, again, their names are never revealed.
