Joslin

English: from an Old French personal name imported into England by the Normans in the forms Goscelin, Gosselin, Joscelin. For the most part it is from the Germanic personal name Gauzelin, a diminutive from a short form of the various compound names having as their first element the tribal name Gaut (apparently the same word as Old English Gēatas, the Scandinavian people to which Beowulf belonged, and also akin to the ethnic name Goth). However, the name also came to be considered as a pet form of Old French Josse (see Joyce).
