Is having a second first name very common in general?

I don't feel like starting a whole new thread about this, but are French last names very common in the US? I can't think of many American celebrities who have French last names.
But SK uses them from time to time, mostly with an English first name: Andy Dufresne (Shawshank Redemption), Gordie Lachance and Teddy Duchamp (The Body) and Eduard Delacroix (The Green Mile).
Or is it just his way of thinking of 'exotic sounding' names?

Maine is quite close to New Brunswick - there are a lot of French speaking people up that way.

I don`t have a middle name.
I don`t think I know anybody from my old country, Serbia, that has one.
Maybe two last names for some reason, but even that is very, very rare....
