Rooted in Greek mythology, Ares entered the US Top 1000 in 2013, when it was one of the year's fastest rising names. Similar in style to Atticus, Atlas, and Ari, it has continued to climb up the charts, and now ranks in the Top 500, given to around 770 babies each year .

Better than Capricorn or Cancer, not as usable as Leo, the name of the Roman god of war becomes more possible as a baby name every day, as mythological names take the place of biblical names.

Subtract the last two letters of Arnold, and you're left with a much more modern-sounding name. Arno is also the name of the main river in Florence, upon which sits the famed Ponte Vecchio. The Italian river name means "flowing water".

Ukrainian Artem (ar-TEM) and Russian Artyom/Artiom (which can also be transcribed as Artem, though still pronounced ar-TYOM in Russian) are ultimately derived from the name of the Greek goddess Artemis: goddess of the moon and hunting. The meaning of her name is unknown, though it may be related to the Greek for "safe" or for "butcher".

The name of the Aster flower, named by the English, was derived from the Greek word for star. Like many floral names, Aster is much more popular among baby girls.

Avis is a bird name that's been in hibernation for awhile, possibly due to the car rental association, but it could make a return on the wings of Ava. Baldwin brother Daniel chose it for his daughter.

A classic in its native Scandinavia, Axel has a cool rock 'n' roll flavor in the US, thanks to Guns N' Roses' Axl Rose (born William). With its distinctive letter 'x', it has an effortlessly cool vibe about it, and is currently growing in popularity.

Putting the emphasis on the "elle" softens a name that seems at once futuristic and medieval.

Azure is a colorful choice for a blue-eyed child, recently chosen by Elon Musk for his daughter. Currently, Azure is used for American baby girls and boys in equal numbers. Among other blue-toned color name possibilities: Indigo, Cerulean, and Blue itself.

When actress Rachel Griffiths chose this highly unusual name for her son, many assumed it was a bizarre invention. But a noted Australian poet (Griffiths is an Aussie) is known by this name.

Bardo has a poetic beginning and upbeat ending, with roots in several diverse cultures. It may be most familiar today via George Saunders' novel Lincoln in the Bardo, which refers to the Tibetan Buddhist state of suspension between one life and the next, resembling the Christian idea of Limbo. Bardo is also an ancient saint's name: Saint Bardo was the eleventh century bishop of Mainz, in Germany. Actress Sandra Bullock chose Bardo as her son's middle.

As Bas, it's a popular name in The Netherlands, but Baz, as in director Luhrmann, has potential for independent life too.

Curiously, Australian-born Moulin Rouge director Luhrmann was born neither Sebastian nor Basil, but had the name Mark Anthony on his birth certificate; his nickname arose from his supposed resemblance to a British TV fox puppet named Basil Brush.

Beata, a Latinate saint's name, has been widely used primarily by Roman Catholics in several European countries, but is rarely heard in English-speaking countries. Playground alert: could be mispronounced Beeta.

Beau suggests someone devilishly handsome, with a large measure of southern charm—a nice image to bestow on your boy. Often solely a nickname in the past, it's now standing firmly on its own. Beau has been on the Social Security list non-stop since 1969.

A beautiful name with a combative meaning (from the Latin bellare "to fight"), belonging to a Roman goddess of war. Bellona has never appeared on the SSA list, but it could be an intriguing option for fans of the popular Belle/Bella.

Benno is a cool name in its own right -- there was a tenth century Saint Benno -- though it is also used as a lively nickname for Benjamin. Saint Benno of Meissen is the patron saint of anglers and weavers and, strangely enough, alliteration.

Well used in northern Europe, almost unknown here.
