Annis

Annis is an English given name that developed as a medieval vernacular form of Agnes, itself derived from the Greek name Hagnē, from hagnos meaning pure or holy. It was fairly common in England during the Middle Ages, when Agnes and its various local adaptations were widely used across the British Isles. Related forms include Annes, Annys, and the more familiar Agnes, as well as the Scottish variant Annys.
