What Cian means
Cian means ancient, enduring or long-lived. The sense is of something that lasts rather than something merely old, which is why it reads as a blessing on a child rather than an odd description of one.
Where Cian comes from
Cian comes from the Old Irish cían, meaning long, distant or enduring, used of time and distance alike. Its mythological bearer is Cian, son of Dian Cécht of the Tuatha Dé Danann and father of Lugh, the god of skill for whom Lughnasadh is named. A historical Cian married the daughter of Brian Boru and fought at Clontarf in 1014. The name also survives in the surname Ó Ciain and in the anglicized Kean and Keane. Cian is sometimes confused in English records with Kian, which is now often given a separate Persian derivation, though in Ireland the two are usually the same name.

Where Cian is used
