The Master List - O

Oak, a symbol of solidity, strength, and longevity, is joining Cedar and Pine as a viable name, one that would work especially well in the middle.

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.

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.

Olwen is a Welsh favorite, the name of a legendary princess in what is believed to have been the earliest Arthurian romance, and in fact one of the first recorded examples of Welsh prose.

Unlike Pearl and Ruby, this is one gem name suited for boys, the final x making it sound strong and virile. Musician Iggy Azalea chose the name Onyx for her son.

Ophelia reentered the US Top 1000 in 2015 after more than 50 years off the charts, and rose more than 600 spots since then, with no signs of slowing down. Could Ophelia may be the next Olivia?

Orin is one of a variety of similarly-spelled names that have a soft and sensitive image. The Orrin spelling has been known nationally via Republican Senator Hatch.

Osiris is the name of Egyptian mythology god-king who died and was reborn every year. Emerging from centuries of obscurity, Osiris has several ingredients for success in the modern world: Roots in ancient myth, an uplifting meaning, an s ending and the cute nickname Os or Oz.

Ottilie is trending in the UK, where the pronounced T helps the name sound pretty and delicate, ala Amelie. Ottilie is less popular in the US, where many Americans pronounce it as a near-homonym for "oddly".

Otto is cool again. Long a quintessential Old Man Name, Otto has been promoted to trending darling of adventurous baby namers.

Curiously appealing, in a hoop-skirted, wasp-waisted way, Ottoline has recently entered the realm of modern possibility, especially since Sienna Miller chose it as the middle name of her daughter Marlowe.

This may be a legitimate Hebrew name denoting power, but to any American kid, it will evoke ruby slippers and a yellow brick road. The full Hebrew name is Ozni, who was a grandson of Jacob in the Bible.

Everyone says they want an unusual name — well, if you truly do, this is one with Biblical cred that fits the bill, with the added attraction of the user-friendly nickname of Oz or Ozzie. Ozias is the name of several minor figures in the Bible. Osias is another spelling.
