English : probably a variant of Joyce. There is a family tradition among bearers of the name that it means ‘chosen’, from Middle English, Old French chois (of Germanic origin). In the Middle Ages the word was used both for an ‘act of choosing’ and a ‘thing chosen’, and as an adjective with the meaning ‘chosen’, ‘select’, ‘favored’. Perhaps this word gave rise to a nickname, but there is no evidence to support this speculation.
