History & Origin

Kienan is an anglicized spelling of Irish Cianan, a diminutive of Cian from the Old Irish word cian, 'ancient, enduring, distant'. The name is carried in early Irish record by Saint Cianan of Duleek. Modern American families most often meet it as Keenan; the Kie- spelling is a newer variant (said 'KEE-nun').

It appears only rarely for boys in the U.S., well behind Keenan. Rare, Irish-rooted, and warm.

Did you know? Behind Kienan is Irish cian — 'ancient, enduring, far-off' — the same root that gives Cian and Keenan; an early Irish saint, Cianan of Duleek, carried it (said 'KEE-nun').
