Iridescent Siren

If you're a lover of the beach and sea, and want a name that relates to the largest body of water, there are several variations you could consider.

Oceane (oh-see-EN) has been one of the chicest names in France for several years, ranking in the French Top 50. This is a sophisticated name that could easily cross the ocean, and is much more stylish than the English Ocean or Oceana.

Odessa, a Ukrainian port city, was given its name by Catherine the Great, who was inspired by Homer's Odyssey. It would make an original and intriguing choice.

Odette is the good swan in Tchaikovsky's ballet Swan Lake, a role for which Natalie Portman won an Oscar ---and it would make a particularly soigne, sophisticated yet upbeat choice, unlike some of the more dated other 'ette'-ending names.

Identified with a region famous for its gold, more commonly spelled Ophira.

At a whopping five syllables long, Olympiada is a lot of name for a little girl. Thankfully, nicknames abound. Try Pia, Ollie, or Ada.

Mythological spirit of the waters; spelled Undine, she was an Edith Wharton heroine.

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?

A rare Italian name derived from Orestes, from Greek mythology.

Oriana is a dashing medieval name, with a meaning similar to Aurora. At this point, though, Oriana is much more unusual than Aurora and makes a unique choice if you're searching for names that mean new beginnings or dawn.

A pretty, feminissima name, more distinctive than Cynthia. George Bernard Shaw used it for a character in his play The Apple Cart, about which it is said 'Orinthia is a name full of magic for me.'

Anthea would be simpler and prettier, though Panthea has possibilities.

Pearl, like Ruby, has begun to be polished up for a new generation of fashionable children after a century of jewelry box storage. The birthstone for the month of June, Pearl could also make a fresher middle name alternative to the overused Rose. Cool couple Maya Rudolph and Paul Thomas Anderson named their daughter Pearl Minnie, followed by Jack Osbourne, and several celebs have put it in the middle spot, as in Busy Philipps's Cricket Pearl, Jake Owen's Olive Pearl and Caleb Followill's Dixie Pearl .

An interesting figure from Greek mythology -- an Amazon queen who fought for Troy in the Trojan War -- but no figure could be interesting enough to make that five-syllable mouthful usable today. Stick with Penelope or, if that's too popular for your taste, try Thessaly.
