Dennis m
English and French: medieval vernacular form of the Greek name Dionysios, which was borne by several early Christian saints, including St Denis, a 3rd-century evangelist who converted the Gauls and became a patron saint of Paris. It was on his account that the name was popular among the Normans. In classical times, the word originally denoted a devotee of the god Dionysos. This deity was a relatively late introduction to the classical pantheon; his orgiastic cult seems to have originated in Persia or elsewhere in Asia. His name is of uncertain derivation, although the first part seems to be related to the name of the supreme god Zeus.
