One of the new crop of boys' names that manage to be unconventional and macho at the same time — though Blade verges on the threatening.

The two X's may be a challenge for even the most intrepid baby namer. Xerxes was the name of two early kings of Persia and the Handel opera Serse or Xerxes is loosely based on Xerxes I.

An evocative word name, conjuring up images of the beautiful low land between hills and mountains, and the streams and rivers that often run through them, Valley has the advantage of also sounding totally name-y. Reminiscent of Ally, Valerie, Valentina, Tally, and Callie, it is a rising choice in the US, more than doubling in popularity in recent years.

Calista Flockhart spotlighted this lovely Greek name that has a long future in the English-speaking world. Kallista is another spelling; Calixta and Calixto are related.

Originally a form of the saint's name Blaise, though now more likely to be a hot word name used for both sexes, though heavily weighted toward the boys. It has been in the boys' Top 1000 since the year 2000. On the pop culture side of things, Blaze Bayley is a singer and musician who has been connected to the bands Wolfsbane and Iron Maiden.

Windswept and dramatic, but perhaps asking for trouble. Quite popular in Denmark and Sweden, where it derives from Stromr, which is a fairly common surname. Storm Thorgerson is a famous bearer of the name - he designed iconic album covers for Led Zeppelin, Black Sabbath, the Cranberries, Anthrax, and Pink Floyd.

This spelling adds a little more femininity to the neutral Lee. Leigh and sister Lee were quite popular in the 1960s and 1970s among the first cool wave of unisex names for girls, but now have vanished from the Top 1000. The Biblical Leah is preferred.

A flower name containing both beauty and power, Lotus has significance in both Buddhism and Hinduism, symbolizing purity, grace and spiritual growth — not to mention a familiar yoga position.

Khaleesi is an invented name introduced to the world by inventive and prolific author George R. R. Martin for his wildly popular Game of Thrones series—it's Dothraki for "queen" and is one of the titles of the character Daenerys. It entered the US Top 1000 in 2014.

Thisbe, the name of a beautiful but tragic lover in mythology, is lively and cute -- in a slightly thistly, prickly way. Ovid retold the story of Thisbe and Pyramus, young lovers in ancient Babylon kept apart by family rivalry, which was the inspiration for Romeo and Juliet. A modern bearer of the name is writer Thisbe Nissen.

In Sarah Dessen's novel Along for the Ride, the baby daughter is named Thisby, nn Isby.

Sharp and spiky with international potential, as a feminine name, Nikita has its roots in Hindi, Marathi, and ultimately Sanskrit. It comes from niketa, meaning "home, habitation", and may also be spelled as Nikitha.

Norman, perhaps because it sounds so much like the word 'normal', conjures up the image of a normal-looking guy with a normal kind of job-- not necessarily an image many modern parents seek for their sons. But though it's been off the national popularity list for several years, Norman is Number 694 on Nameberry. It was a Top 100 name for more than half a century, hitting a high in 1931 at Number 36, but today it's nowhere near one of the most popular boy names starting with N.

Flint is one of the new macho names on the rise today, part old-school tough guy, part rebel. You won't find a tougher, steelier-sounding name; it's part of a genre on the rise along with cousins Slate, Stone and Steel.

Daniella, Daniela, and Danielle were among the hottest names for twenty years, but now, though still popular, they can no longer be considered stylish options, lagging behind the newer Ella, Stella, Bella, Gabriella, and Isabella.

Simple and yet distinctive, Ara is a mythological name of a famously handsome king. Although it originated as a boys' name, in the contemporary US, it's now much more commonly used for girls.

The girls have Violet and Scarlet and Ruby and Rose, but for the boys there's a much more limited palette of color names. Grey/Gray is one exception, which could make for a soft and evocative—if slightly somber—choice, especially in the middle. Kaitlin Olson and Rob McElhenney named their son Leo Grey.

Rose and Briar are popular, and Hawthorn is cool – so why not the equally prickly Thorn? Add an E to give it a surnamey spin.

The dynamic personality and paintings of Mexican artist Frida Kahlo have inspired growing numbers of parents to resurrect this form of the name. It does much better in certain European countries, especially in Denmark and Norway. The Frieda and Freida spellings were more popular in the US until the middle of the 20th century.

Alethea, the name of the Greek goddess of truth, came into fashion in England in the 16th century, in tandem with the virtue names. Alethea may find new favor now, thanks to its similarity to Athena, Ophelia, and Alessia, and because it gets you nickname Thea.

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.
