Kathlyn

Kathlyn is an English variant spelling of Kathleen, which itself derives from the Irish Caitlín, a medieval Gaelic form of Catherine. Catherine traces back through Latin Catharina and Greek Aikaterinē, a name whose ultimate origin is debated but commonly associated with the Greek root katharos, meaning pure. The name gained widespread use in the Christian world largely through the veneration of Saint Catherine of Alexandria. Related forms include Katelyn, Kaitlyn, Katlyn, and Kathleen.
