An emphasis on the O

Not a super common vowel in names, a name with a strong 'O' sound can help balance out a sibling set!
  1. Antonia
    • Origin:

      Latin
    • Meaning:

      "from Antium"
    • Description:

      Antonia is stronger than most feminized boys’ names, reflecting the pioneer spirit of Willa Cather's classic novel My Antonia. Antonia is hovering near the bottom of the US popularity list, which may be an excellent reason for you to use it.

      "between two hills"

  3. Begonia
    • Origin:

      French
    • Meaning:

      "Begon's flower"
    • Description:

      Begonia is a pretty flower named for French administrator and amateur horticulturalist Michel Bégon, who was an avid naturalist but also a proponent of slavery. A rare floral choice which has never really caught on as a baby name, Begonia would certainly stand out from the Lilys and Roses.

    • Meaning:

      "order, beauty, universe"
    • Description:

Now some pioneering parents are embracing this expansive Greek name, which makes a creative and cool choice for a baby. Influential celebrity couple Scarlett Johansson and Colin Jost chose it for their son, born in 2021, which will likely drive Cosmo up in popularity. In the UK, it currently ranks within the Top 1000 boy names and is trending upwards.

    • Meaning:

      Greek
    • Meaning:

      "demi-god"
    • Description:

      Despite the possibility of gender confusion, the Hero in Greek myth was a woman. Myleene Klass got that when she chose Hero for her daughter, and Sam Taylor-Wood and Aaron Johnson used it as their daughter's middle--and we wouldn't be surprised to see more girls with this heroic name.

    • Meaning:

      "god of frenzy; poetic fury"
