Coleen
Meaning
“A variant spelling of Colleen, taken directly from the Irish word 'cailin', meaning girl.”
The story
Coleen is the one-l spelling of Colleen, and the name itself is an American invention with an Irish accent: it comes straight from the Irish word cailín, girl, which was never used as a given name in Ireland itself. Irish emigrant families in America heard the word as an endearment and made it a daughter. The US curve registers from the 1910s, bumps gently through the 1950s to the 1970s, then fades until, by the 2020s, it no longer registers at all. That makes Coleen a completed story in the data, a keepsake of the generation that wanted its Irishness written on the certificate, one l lighter than its sister. Its spelling now preserves a particular American Irish-fashion moment rather than ordinary present-day usage in Ireland.
