Jocelynn

Jocelynn is a modern spelling of Jocelyn, a name that reached English through medieval French forms of a Germanic personal name. The older history is usually connected with a tribal name and a diminutive ending. It is not securely explained by splitting the modern spelling into joy and Lynn.

Jocelyn has been used for both men and women over its long history, while Jocelynn is a later written adaptation. The extra final n preserves the familiar sound for many English speakers and makes the Lynn-like ending more visible. A family may use that spelling to echo a relative's name, but the personal tribute is separate from the medieval derivation. Jocelyn remains the clearest comparison when exploring its history.
