Joisse

This name derives from the Breton “Judoc” after Latinized “Iudocus,” composed of two elements: “iudd” (chief, lord) plus “oc” (diminutive suffix). In turn, the name means “little lord, young lord.” Between the end of the Middle Ages and the end of the 14th-century, it fell into disuse as a male name, barely surviving as a feminine. The name Joyce has resumed its success, perhaps also thanks to the medium English term “joise,” which means “rejoice,” which, however, comes from the Latin “iŏcōsus.” Saint Judoc, Saint Joyce, or otherwise known as Saint Josse (600–668 AD), was a 7th-century Breton noble. Though he was never officially canonized, Saint Judoc is considered to be a saint. Judoc was a son of Juthael, King of Brittany. He renounced his wealth and position to become a priest and lived alone for the rest of his lifetime in the coastal forest near the mouth of the River Cache. The feast day is traditionally celebrated on December 13.
