An uncommon Greek pick — distinctive and rare.
Kathlyne is a girl's baby name, an elaborate variant of Kathlyn or Kathleen, of Irish and Greek origin, from the Irish Gaelic Caitlín, itself the Irish form of Catherine, meaning 'pure.' The -yne ending adds a slightly more unusual visual quality.
Kathleen and its variants have a warm Irish-American heritage. Kathlyne carries that Celtic purity in a spelling that feels both vintage and personally distinctive.
Kathlyne has 11+ years of history in the U.S., first appearing in 1914.
