Judoc

Judoc is a medieval Breton given name derived from the Old Breton element *iud*, meaning "lord" or "chief." It was borne by a 7th-century Breton saint, also known as Josse or Joyce, who according to legend renounced his kingship to become a hermit and pilgrim, eventually settling in Ponthieu in northern France; his cult spread to England and Normandy during the medieval period. The name appears in Latin records as Iudocus and gave rise to the anglicized form Joyce, which later developed as both a surname and a given name.
