Boys names ending in -s and -o

  1. Giorgio
    • Origin:

      Italian variation of George
    • Meaning:

      "farmer"
    • Description:

      Giorgio as is rich in meaning and history as George, but with more Italian flair. It's a consistent Top 50 hit in Italy, and with Italian boy names like Gianni and Lorenzo rising through the charts, could be another one to add to the mix.

    • Meaning:

      "son of Harry"

      Spanish variation of Julius

      What with Paul Simon's classic lyric about Julio down by the schoolyard and several distinguished bearers, this livelier Spanish version of Julius is completely familiar to the non-Hispanic community and would make a great choice for a bicultural family.

    • Meaning:

      "flax"
