There was a little restaurant downtown that used to have French printed menus for folks from the nearby elder home. I also seem to remember that if there were dual language items in a store it would be english/french instead of the more common english/spanish.

This was of course 20+ years ago and that was really the only evidence at the time other than some decidedly french sounding last names.
