Favorite girl names that start with O

Oakley, with its nature name roots and its Annie Oakley charm, is a hot name for both genders but more than twice as popular for girls. This name made it into the Top 1000 for the first time in 2013, one of only four girl names starting with O to rank that high. A decade letter, it's aiming for the Top 100.

Though greatly overshadowed by the trendy Olivia, Olive has a quiet, subtle appeal of its own -- and is now enjoying a remarkable comeback. Olive is one of only four girl names starting with O on the US Top 1000. Cool couple Isla Fisher and Sacha Baron Cohen chose it for their daughter, reviving the name to stylishness, and now Drew Barrymore has a little Olive too, as has country singer Jake Owen.

Oona is a name made famous by Eugene O'Neill's daughter, who became Charlie Chaplin's wife. One of the original Oona's granddaughters was named after her, and is now an actress famous in her own right for playing Talisa of Volantis in HBO's "Game of Thrones." The double-o beginning gives their name a lot of oomph.

Opal is on the verge of a repolishing, following other jewel names like Ruby and Pearl. A Top 100 name during the first two decades of the twentieth century, the opalescent Opal has a good chance of coming back as another O-initial option.

Floral, elegant, and bold, Ophelia re-entered the US Top 1000 in 2015 after more than 50 years off the charts. It has risen more than 700 spots since then and shows no signs of slowing down. Now in the US Top 300, could Ophelia one day become the next Olivia or Amelia?

Orchid is a hothouse bloom that has not been plucked by many modern baby namers — yet. In the language of flowers, orchids symbolize love, beauty, and sophistication.

The advantage of Orsa over the arguably-more-attractive Ursula is that it breaks the tie to the hideous she-witch of The Little Mermaid. Orsa definitely feels more ready for modern life now that brother name Orson is on the rise.

Orsola is chic in Italy in a way that Ursula is not in the U.S. And English speakers will inevitably hear this chic, sleek name as Ursula, condemned to purgatory as the name of the hideous sea-witch who terrorized Disney's Little Mermaid.
