This name means “ancient,” or “enduring.” In the Irish legend, Cian Mac Mael Muad was the son-in-law of Brian Boru, both of whom were killed in the Battle of Clontarf.

Cillian (pronounced: kill-ee-an)

The popular name Cillian has several known meanings, including “war,” “strife,” and “bright-headed.” The word cille also means “associated with the church,” so the name is often associated with the word “church” or “monastery.” There are several Saint Cillians in Irish history, including one in 650 AD who was sent to Bavaria to convert the natives and was martyred for his trouble.


Conor is the Anglicized form of the Gaelic name Conchobhar, a compound name composed of “conn” (wisdom, counsel or strength), “con” (hound or dog), and “cobhair” (aid). It is usually translated as “lover of hounds.” It can also mean “high desire,” as derived from the Irish word “coachuhhar.” Conchobhar MacNessa was the king of Ulster - according to the legend, he was born on the same day as Christ.

Darragh (pronounced: dara)

Some translate Darragh into “fruitful” or “fertile,” and some translate the name into “dark oak” or “oak tree.” According to the Irish legend, Daire Mac Fiachna owned the Brown Bull of Cooley, and his refusal to sell it to Queen Maebh was part of the cause for the fight between Ulster and Connacht.


Finn is the Anglicized version of Fionn. Meaning fair, blonde, or “small blonde soldier.”

Fionn (pronounced: finn, fee-in or fyonn)

Fionn is a Gaelic name meaning “fair-headed,” “white” or “clear.” Other translations include “small blonde soldier” and “handsome.” Fionn MacCool was a central character in Irish folklore and mythology - he was the leader of the warrior band “The Fianna.” He wasn’t known to be incredibly strong, but he was known for being brave, handsome, wise, and generous. He acquired his wisdom by touching the “salmon of knowledge” and then sucking his thumb.
