Jodocus

Jodocus is a Latinized form of the Breton name Iodoc, derived from the Old Breton element iud, meaning lord or chief. It was borne by a seventh-century Breton prince and hermit who became venerated as Saint Josse, and his cult spread widely through medieval Europe, lending the name considerable popularity in ecclesiastical and scholarly contexts. The name appears in numerous regional forms across different languages, including Jost in German-speaking lands, Joyce as a surname-turned-given-name in English, and Josse in French.
