TorinHeart

  • Origin:

    Irish
  • Meaning:

    "chief"

    Irish
  • Meaning:

    "sea warrior"
  • Description:

    This jaunty Celtic surname -- the most common family name in Ireland -- is totally viable as a first. Although there was a possibility of its being feminized via the old TV sitcom "Murphy Brown," it has never taken off for girls and very much retains its masculine image.

KeirHeart

  • Origin:

    Irish
  • Meaning:

    "dark, black"
  • Description:

    Keir is a single-syllable name that packs a lot of punch, might suggest -- thanks to its similarity to the word care -- a caring person. Sir Keir Rodney Starmer is a British politician and head of the Labour Party in 2020. Keir Dullea is an American actor who starred in 2001: A Space Odyssey.

    Irish version of Malachi, Hebrew

    "second"
  • Description:

    This spelling, which came to the attention of readers of the best-selling Angela's Ashes as the name of author Frank McCourt's father and brother, the latter of whom wrote a bestseller of his own, lends the biblical name a more expansive, almost boisterous image.

BradyHeart

  • Origin:

    Irish
  • Meaning:

    "broad meadow or large-chested"
  • Description:

  • Meaning:

    "God is gracious"
  • Description:

    Though Eoin is a Gaelic form of John, its Anglicized pronunciation links it directly to Owen. Eoin is currently a Top 30 name in Ireland. Other variations: Ewan, Ewen, Evan and Eoghan (pronounced as Owen but also translated as Eugene).

DarcyHeart

  • Origin:

    English from French, d'Arcy
  • Meaning:

    " from Arcy"
  • Description:

    Though Darcy is the ultimate Jane Austen hero name, it is rarely used for boys today though it's on the upswing for girls. A shame as it's a handsome, roguish kind of appellation that combines elements of French flair, aristocratic savoir faire, and a soft Irish brogue. And in terms of image, it's one of the quintessential English names for boys.

NiallHeart

  • Origin:

    Irish
  • Meaning:

    "cloud"
  • Description:

    Niall is pronounced nye-al--something like Neil, but this Irish spelling of the name makes it much more current and cool.

KellenHeart

  • Origin:

    German; Irish
  • Meaning:

    "swamp; slender"
  • Description:

    Kellen is German in origin and Irish in spirit. Kellen has fallen a bit in popularity for boys since its peak in 2012, but it has possibilities for girls too.

CullenHeart

  • Origin:

    Irish
  • Meaning:

    "holly tree"
  • Description:

    Cullen is an appealing Irish surname name that upped its cool factor considerably when it became the Twilight family name of Edward et al. It's considerably less popular than it was at its peak in 2010, but is still widely used.

    Irish and Scottish

    "slender, angular"
  • Description:

    Attractive Scottish and Irish surname name of a seventh-century saint, associated with the illusionist and escape artist David Blaine.

    Irish
  • Meaning:

    "little dark one"
  • Description:

    Extremely popular in Ireland, Ciaran is also well used in England and is beginning to be adopted by parents in the U.S., though usually via the more American-friendly Kieran spelling.

DevinHeart

  • Origin:

    Irish
  • Meaning:

    "poet"
  • Description:

    Devilishly handsome, Devin arrived as Kevin was moving out. Not to be confused (though it often is) with the English place-name Devon. While both Devin and Devon are flagging somewhat for boys, the names have dropped out of the Top 1000 for girls, making it more a masculine and less a unisex name these days.

TullyHeart

  • Origin:

    Irish
  • Meaning:

    "flood, peaceful, or hill"
  • Description:

    Tully is a relaxed, rarely used Irish surname possibility. Sources disagree on the meaning, depending on what root is used. The Irish tulach means hill or mound, while tuile means flood. Other sources relate it to the Roman Tullius, most notably the name of the philosopher Marcus Tullius Cicero, sometimes anglicized as Tully. Statesman Alexander Hamilton used the pen name Tully when he wrote editorials denouncing the instigators of the Whiskey Rebellion.

    Perhaps the most remarkable O'Grady descendant is Muhammad Ali, whose mother's maiden name was Grady.
