My surname is Engard, of Scandinavian origin (pronounced en'-guard). I hear "en garde!" a lot. But I don't recall ever hearing that while I was at school, just later in life, from the adults I meet. I try to just ignore it, but maybe roll my eyes a bit.

My first name is Susan. For 4 or 5 years I lived on Suzann Drive. To me, Susan and Suzann are completely different names, but whenever I gave my address to someone they seemed compelled to comment on the similarity.
