      Irish
    • Meaning:

      "dark challenger; dark river"

      Delaney has been a popular surname-style choice since 90s, when it joined other Irish surnames such as Cassidy, Kennedy, and Mallory on the US Charts. Buoyant, bright, and cheerful, it ranks in the US Top 250 and is given to nearly 1300 babies every year.
  3. Darcy

      "dark one, or from Arcy, or from the fortress"

      Delicate ballerina name with grace, charm, and heft courtesy of Jane Austen's Mr.
  4. Darcy
    • 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.
  5. Dara
    • Origin:

      Hebrew, Slavic or Irish
    • Meaning:

      "pearl of wisdom; gift; or oak tree"
    • Description:

      Though Dara was an (extremely wise) male figure in the Bible, this name feels mostly feminine to modern Americans. The Irish Gaelic version, Darragh, is well-used in contemporary times for boys.
  6. Dallas
    • Origin:

      Place name, surname and Irish
    • Meaning:

      "meadow dwelling, valley house, skilled"
    • Description:

      A laid-back cowboy name which feels both cool and gentle, Dallas has ranked in the US Top 500 since records began in 1880. Never super popular but surprisingly never out of style, Dallas is given to nearly 1400 boys in the US every year.
  7. Darby

      Irish or Norse
    • Meaning:

      "free from envy, or from the deer estate"

      Irish
    • Meaning:

      "loyal"
    • Description:

      Different origin from the Welsh Dylan, but increasingly used as a variant spelling to honor Bob Dylan or Dylan Thomas. Still, the Dylan spelling is found 20 times as often as Dillon.
  9. Deirdre
    • Origin:

      Irish
    • Meaning:

      "sorrowful"
    • Description:

      Sadly, this strong Celtic name often has "of the sorrows" attached to it because of the tragic character in Irish legend. Also a bit drab when compared with newer Irish imports.
  10. Devin
    • 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.

      Irish
    • Meaning:

      "little great one"
    • Description:

      Cheerful but laidback, surname-style Delaney is derived from the Old Irish name Dubhshláine and has become a familiar choice for girls in recent decades. Nevertheless, it has also been used for boys since the early 1900s and was equally - though rarely - given to both, right up until the 1990s.
  13. Devlin
    • Origin:

      Irish
    • Meaning:

      "unlucky"
    • Description:

      Irish or Norse
    • Meaning:

      "free one or from the deer estate"

      Irish
    • Meaning:

      "oak tree"

      Irish
    • Meaning:

      "oak tree"
    • Description:

      Daire, along with brother names Dara and Darragh, is among the Top 100 boys' names in Ireland today. An ancient name with an inspirational meaning, pronunciation could prove confusing to Americans.
  18. Devin
    • Origin:

      Irish
    • Meaning:

      "poet"
    • Description:

      Used far more for boys with this spelling, but still has a nice impish Irish feel for a girl.

      Place name, surnamed and Irish
    • Meaning:

      "skilled"

      A name with a bit of glamor but also cowgirl vibes, Dallas entered the US Top 1000 for girls in 1992. It fell out of style during noughties, but reappeared in 2012 when other gender neutral names like River, Sawyer, Rowan, and Blake were also climbing fast.
