He is credited with converting the Gauls to Christianity and is considered the patron saint of France.This name was common in France during the Middle Ages, and it was imported by the Normans to England. It is now regularly spelled Dennis in the English-speaking world. A notable bearer was the French philosopher Denis Diderot (1713-1784).
