    • Meaning:

      "resolute protection"

      "devotee of St. Colomba"
    • Description:

      Malcolm is a warm and welcoming Scottish appellation (originally Mael-Colium) that fits into that golden circle of names that are distinctive but not at all odd. A royal name in Scotland, Malcolm is also a hero name for many via radical civil rights activist Malcolm X.

      Hebrew
    • Meaning:

      "son of the red earth"

  7. Caelum
    • Origin:

      Latin
    • Meaning:

      "heaven"
    • Description:

      A constellation name that could have broad appeal beyond astronomers and astrophysicists, Caelum blends the sounds of Scottish Callum and modern Caden. It comes from the Latin caelum meaning "heaven, sky", giving it a subtle spiritual air and linking it to the names Celia, Cielo, and Ciel.

    • Origin:

      English
    • Meaning:

      "Tate's homestead"
    • Description:

Khloe Kardashian made headlines when she revealed her son is named Tatum Robert, breaking from the family theme of using unique word names for their children.
  9. Bram
    • Origin:

      Dutch variation of Abraham, Hebrew
    • Meaning:

      "father of multitudes"
    • Description:

      Bram has an unusual measure of character and charm for a one-syllable name; it started as a hipper-than-Abe diminutive of the biblical Abraham, but is also an independent Irish and Dutch name, made famous by Irish-born Dracula creator Bram (nee Abraham) Stoker. Bram is currently Number 16 in the Netherlands; Bram Howard was a character on The West Wing.

      Hebrew
    • Meaning:

      "fruitful, fertile, productive"

      Hindi or Arabic
    • Meaning:

      "law; given by God; blessing"
    • Description:

      With Liam at the top of the boys' popularity list, parents might discover the still-rare Niam.

      English
    • Meaning:

      Hebrew
    • Meaning:

      "father of multitudes"
    • Description:

      Abraham is among the most classic baby names that's still widely-used today, popular for its references to both the Bible and American history. The Biblical Abraham was the first of the Old Testament patriarchs and is considered the founding father of the Jewish people. He was originally named Abram, until, according to Genesis, he was told, "No longer shall your name be Abram, but your name shall be Abraham, for I have made you the father of a multitude of nations."

      English, diminutive of Samuel
    • Meaning:

      "told by God"
    • Description:

      Sam has long been used on its own for boys, as accepted standing by itself as it is as a short form of Samuel. Straightforward and down-to-earth, Sam is the name of the son of the co-stars of The Americans, Keri Russell and Matthew Rhys. Sam is one of the most popular names that start with S in the Western world, ranking higher in several European countries than it does in the US, where it's trended downward since the 19th century, though it's always been in the Top 1000.

      English
    • Meaning:

      "shield's son"

  17. Anselm
    • Origin:

      German
    • Meaning:

      "with divine protection"
    • Description:

      A somewhat solemn appellation, Anselm is a saint's name, connected to the twelfth century archbishop of Canterbury, and in modern times tied to the German neo-expressionist painter Anselm Kiefer.

    • Origin:

      Hebrew
    • Meaning:

      "father of multitudes"
    • Description:

      Abram was Abraham's original name in the Bible; it's more user-friendly but with a bit less gravitas. And it does offer that cool nickname Bram, as well as the friendly Abe. After some early American usage, in 1936 Abram completely disappeared for nearly forty years, until its return in the 1970s.
  19. Willem
    • Origin:

      Dutch variation of William
    • Meaning:

  20. Hiram
    • Origin:

      Hebrew
    • Meaning:

      "brother of the exalted one"
    • Description:

      Hiram is the kind of forgotten biblical name that adventurous parents who wish to move beyond David and Daniel are beginning to reconsider--even though it has bits of its old stiff-collared image clinging to it, along with a little hillbilly feel as well.
