Irish Boy Names

This surname borne by several early Welsh leaders has a lot of energy.

This anglicized form of the Irish surname Ó Cathaláin links back to the Irish given name, Cathal. Similar to Callum, Caleb, and Calvin, it might feel more usable outside of Ireland and Scotland than its origin name.

Eamon is one of the traditional Irish names that has not yet emigrated to the US. This Irish name pronounced ay-mon was popularized by early president of the independent republic Eamon de Valera (birth name George), who was born in the United States to an Irish mother and a Cuban father. Eamon definitely has possibilities as a successor to the epidemically popular Aidan/Aiden.

Honest and sincere, laid-back and creative, Emmet is a male cognate of the megapopular Emma and Emily, but the more common spelling is Emmett. Emmet dropped off the US Top 1000 in 1934 and reentered the list in 2014; Emmett, on the other hand, has never been off the charts.

Finn is a name with enormous energy and charm, that of the greatest hero of Irish mythology, Finn MacCool (aka Fionn mac Cuumhaill), an intrepid warrior with mystical supernatural powers, noted as well for his wisdom and generosity.

Fintan is an ancient Irish saints' name that in legend is also the name of the only person to survive The Flood. Popular in modern Ireland, Fintan is ripe for export to the US where it is rarely used but could make an excellent long form for the stylish Finn.

Killian – aka Cillian – is a spirited yet resonant Gaelic name that was borne by several Irish saints and could make a distinctive replacement for the dated Kelly. Kylian is another spelling that's gaining traction, thanks to French soccer star Kylian Mbappé. Possible downsides: an unsavory first syllable and a connection to the trendy brew.

Lorcan is a name rich in Irish history as belonging to several kings, including the grandfather of the most famous high king of Ireland, Brian Boru. Lorcan O'Toole, known in English as Laurence O'Toole, is the patron saint of Dublin, so it's not too surprising that Irish-born actor Peter O'Toole named his son Lorcan.

Jaunty and raffish, Rafferty is one of the most engaging of the Irish surnames, used by Jude Law and Sadie Frost for their son. Fortunately, it doesn't still go by its original form: O'Raighbheartaigh.

Tiernan is the slightly edgier and sharper cousin of Kiernan. This is one Irish surname that is attractive but distinctive; Tierney is another, related, option.

This name of eighteen Irish saints of the past is relatively popular in Ireland, though little known outside it.
