Looked under my proper name - Stephen. Found exactly what I expected, except that there was no French version listed. A severe oversight!
Because: I was called Etienne by my prep school French teacher, and continued being occasionally known by the French version throughout my college years - where I majored in French. I still use it when communicating with friends who speak the language.
The name means "Crown." Which is why some of my closest friends call me "Sir!"
