The name may derive from Josselin (Breton: Josilin) introduced after the Norman invasion and conquest of England in 1066. In turn the name derives from the Germanic “Gautelen / Gautselin”, from the element “Gauta” (Gothic, the tribe of the Goths). The word "Goths" derives from the stem Gutan-". This stem produces the singular *Gutô, plural *Gutaniz in Proto-Germanic. In French, the spelling "Jocelyn" is exclusively male. The female counterpart is spelled "Jocelyne".
