My family came from Switzerland about 200 years ago, and our name is recognizably Swiss. I actually got my passport temporarily confiscated and went through an interrogation about 20 years ago (before 9/11/2001) because they didn't believe I was an American. The fact that I was speaking to them in German was used as evidence against me - because how on earth would an American know German? I giggle at the idea that my ancestral home interrogated me, but the border guards when I went to scary communist China or muslim Turkey barely opened the cover of my passport before they passed me through. But really the worst I've ever been treated was coming back into the US from Canada...
