And that's just bull, them saying they did it to honor their German ancestory.
Yes, and Hitler was also Austrian
Also, as someone who is of both (partially) German and Austrian ancestry, I can tell you that no sane person of that background wants to associate themselves with Hitler. In fact, most of us want nothing to do with him.
Certainly, if they were going to give their kid a cartoonish German/Austrian name, they couldn't have named Adolf "Schnitzel"? Or "Strudel"? Or "Von Trapp"?
