Dennis m. Latin Dyonisius, from Greek Διόνυσιος 'of Dionisos'.

The name of a 3rd C saint, the patron of Paris, and a 12th-13th C king of Portugal.

Dionysius was sometimes used as a latinization or anglicization of Irish Donnchad (cf. Duncan). The vernacular English form Dynys and Dyonys are witnessed in 1379 in the relational bynames Dynysmañ (WRYPT1 p. 146) and Dyonysmañ (WRYPT1 p. 130).
