A medieval name that likely began as a diminutive of Latin Justus, later used in English and French forms.
Meaning
The excerpted 19th-century sources connect Jocelin with Joscelin and describe it as a diminutive formed from Latin Justus, meaning “just” or “righteous.” One source also notes it as a French and English form, and another links it to the German name Jost as a rendered equivalent. In the material provided, it appears as a name with medieval Christian-name roots rather than a direct biblical name.
