From the Middle English male given name from Old French Joscelin, German Gautzelin, diminutive of names beginning with the tribal name Gaut (“a Geat, a Goth”), the root form of which probably comes from Proto-Germanic *Gautalinþiz (from *gautaz + *linþaz); also used as a diminutive form of the Breton name Josse (= Joyce). It survived as a surname and was revived as a given name in the nineteenth century. * Jocelyn is currently popular among U.S. Hispanics, and in the Philippines, by folk etymology explained as a feminine diminutive form of José (Joseph).
