MargoHeart

  • Origin:

    French, diminutive of Margaret
  • Meaning:

    "pearl"
  • Description:

    Margo and Margot sound exactly the same, so why has the Margot spelling hopped back onto the Top 1000, outpacing Margo in numbers more than two to one? (Over 350 baby girls were named Margot in the most recent year, versus 150 named Margo.)

CleoHeart

  • Origin:

    Greek
  • Meaning:

    "glory"
  • Description:

    Cleo, one of the few girls' names to boast the cool-yet-lively o ending, is of course short for Cleopatra, the name of one of the most powerful women in history.

HaloHeart

  • Origin:

    English, word name
  • Description:

    The word has been used in English since the sixteenth century, and in the sacred sense since the seventeenth; it replaced “glory,” the older term for divine light. Being a modern word, Halo didn’t become used as a name until around the nineteenth century. Halo is now mostly given to girls, and has become more common since the Halo video game series was released in 2001, in which Halo rings are huge structures used as weapons, but do have a religious connection. A space age virtue name and possible honour name for Gloria.
