A member of the Gauts tribe
Jossalynn is a modern American elaboration of Jocelyn. It traces back to the Germanic name Gautselin, which referred to the Gauts, a North Germanic tribe. The suffix '-lynn' is a popular contemporary addition that softens the name and gives it a more feminine, rhythmic quality.
