400+ Irish Last Names (With Meanings and Popularity)

One of the cool new surname-names for girls, likely influenced by the stardom of Patrick Dempsey (aka McDreamy).

A lively boys' name that works well for girls.

Though we usually think a name's image in contemporary culture supersedes its ancient meaning, this is a case where the definition could undermine a child's self-esteem.

Cagney is one of the spunkiest Irish surnames around, and could make a lively and fresher successor to the tired Casey.

Calloway is one of those irresistibly jaunty, animated three-syllable surnames, like Sullivan and Finnegan — but this one has the added attraction of jazzy ties to the immortal "Dean of American Jive," Cab Calloway. For a girl, this could be an unconventional route to the cool nickname Callie.

A little further down the road paved by Aidan and Logan.

Along with many other Irish surnames, Conley is picking up in use among both boys and girls.

This familiar Irish surname, best known as the name of the mononamed Welsh female singer, is extremely rare as a first name in the US but could make an original Irish choice.

Variously spelled trendy name in the 1970s that hasn't even been in the Top 1000 in a decade.

This name was consistently in the boys' Top 200 until WW2. It's a name with so many dimensions to it: the hyper-masculine meaning, the surname-as-firstname trendiness, and the softer sound and connotation since homophone Carol was favoured in the 1940s and '50s for daughters. We think it's time for a resurgence of Carrolls amongst the boys.

Fey, for middle name purposes, could be thought of as a fey spelling of Fay. These days, however, Fey would be considered by most people to be honoring comedian Tina.

Stronger and more contemporary twist on Carla or Carly, Carlin was used just about equally for girls and boys in the US last year.

For better or worse, this name is still firmly attached to the TV series Gilmore Girls. It's one of a number of Scottish and Irish surname names beginning with Gil, meaning "servant". In this case, it's "servant of Mary", making it a subtle male Marian name.

Currently more popular among baby girls than boys — perhaps due to the association with Irish folksong "Molly Malone."

Logan came from nowhere in the past few decades to break the Top 25, and Hogan is a good bet to follow, now that "Hogan's Heroes" has faded from memory.

Popular in Israel for girls and boys born on Shavout, a harvest festival. In Babylonian mythology, Dagan was the god of the earth and grain.

Has a harmonic feel.

This Irish surname packs a lot of attitude, projecting an image of spunk and sass. The Welsh singer Duffy, born Aimee Anne Duffy, is best known for her songs Mercy and Warwick Avenue.

Hennessy has attracted some notice as a first name via rapper Cardi B's sister Hennessy Carolina. It certainly has a pretty sound and can hold its own with the new generation of Irish names for girls that originated as surnames, such as Kennedy, McKenna, and Riley. Hennessy is also the brand name of a cognac, which is how Cardi B got her stage name -- her nickname was Bacardi.

Connolly, an alternate spelling of Connelly, could make a livelier and less common substitute for Connor.
