The story of Katelyne
Caitlin came to American parents from Irish and swept through the record in a dozen spellings, Kaitlyn, Katelyn, Caitlyn, Katelynn. Katelyne adds an e at the end, the way French finishes Madeleine, which makes the name look older than it is. No record explains who first chose it.

a form of Caitlin, from Catherine
Caitlin is the Irish form of Catherine, whose own meaning is argued. Katelyne is a spelling of it, and its final e adds nothing to the sound.
