What does Cian mean?

Cian is an old Irish name meaning “ancient” or “enduring,” borne by figures of Irish myth and history. The modern Irish word cian means “long” or “distant,” as in a long time or a distant place. In English the name has been written Kian, Kean or Cain.

In Irish mythology Cian was the father of Lugh Lámfada. The O’Haras and O’Garas of Connacht and the O’Carrolls of Ely took the name from their ancestor Cian, son of Olioll Olum, King of Munster. The O’Mahonys took it from Cian son of Máel Muad, remembered as Brian Boru’s son-in-law and as leader of the Desmond forces at Clontarf in 1014; he was killed the same year in a separate battle with Domnall son of Dub dá Bairenn.
