Oh Boy Names

Four letter boy names containing an O that we would consider. Most are a bit on the edgy side.
  1. Milo
    • Origin:

      Latin and Old German
    • Meaning:

      "soldier or merciful"
    • Description:

      Milo is most commonly considered to be Germanic name derived from the Latin word miles, meaning "soldier." However, there is evidence to suggest it also may have independently spawned from the Slavic root milu, meaning "merciful." Milo predates brother name Miles, a variation that evolved when the name immigrated to the British Isles in the Middle Ages. Mylo is an alternate spelling.
  2. Owen
    • Origin:

      Welsh
    • Meaning:

      "young warrior; well-born"
    • Description:

  3. Rory
    • Origin:

      Irish
    • Meaning:

      "red king"
    • Description:

      Latinized form of Hugh
    • Meaning:

      "mind, intellect"
    • Description:

      Hugo, the Latin form of Hugh, has more heft and energy than the original -- and of course we love names that end (or begin, for that matter) with an o. This one is especially appealing because it's backed up by lots of solid history and European style.
  5. Otis
    • Origin:

      Variation of Otto, German
    • Meaning:

      "wealthy"
    • Description:

      "round hill"
    • Description:
