The problem with having a French last name is having an email address that it's easy for French speaking people to send email to. I've gotten for people looking for Marc Laroche, and Michael Laroche, both in French.
Interesting tidbit: I reply using Google Translator (saying "sorry, you have the wrong email address" but in French) and both times people have replied in English (just a few words).
I feel pretty ashamed for being this lame with French and having a French last name. Whoops!
