Denis is a continental form of Dennis and ultimately comes from a Greek name meaning "devoted to Dionysus". It feels traditional and slightly more European in flavour than Dennis.
The name spread through Christian Europe partly because of Saint Denis, the patron saint of France. That saintly connection helped separate it in feeling from its older pagan root.
