The patron saint of comedians and dancers (also known as St Vitus) has a name that is both the ultimate everyman, and has a hint of British aristocracy. In the States, Guy was most popular in the 1950s. Now he hovers steadily below the Top 1000, in the sweet spot of familiar but not overused. With the meteoric rise of Kai, Guy may have potential with parents looking for a more classic name with a similar sound.

Drew, which projects a polished, somewhat intellectual impression, is rapidly becoming the Andrew nickname of choice, replacing the past favorite, Andy. It is fully capable of standing on its own, which it has for many decades, non-stop since 1942.

Greta is an Old World name long tied to the iconic Garbo, but now synonymous with environmental activism.

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 picking Pearl Clementine. 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 .

Now that many dogs are named Max, it's safe to use this sleek, solid, regal name again for your child. And with the charm of its final x, its regal meaning, and its offbeat simplicity, Rex is definitely one to consider.

While Gwen may have originated as a short form of Gwendolen and Gwendolyn, these days it frequently stands on its own. Rocker Gwen Stefani has given it a shot of cool, and parents are choosing it as a standalone more and more often—Gwen hopped back onto the US Top 1000 in 2013 after an absence of over 30 years. Gwen could also be short for Guinevere.

Monty, a name with a World War II feel, is rarely used on its own in the US. But we're hearing rumblings of a comeback and think that Monty, whatever it's short for, is an adorable vintage nickname name of the future. It's already a hit in the UK.

Fresh, bright, and sunny, Della could be an alternative to Ella, Delilah, or Adeline. Familiar but not yet overused, it combines the elements of contemporary favorites with vintage charm.

Cal is a nickname style name that feels as friendly and calm as it does cool and breezy. While its longer forms have proved more popular over the years, Cal as a stand alone has dropped on and off of the US Top 1000 since the 1880s.

Sasha, largely male in Russia--and also spelled Sascha and Sacha--is an energetic name that has really taken off for girls here, chosen by Jerry Seinfeld (using the alternate Sascha spelling) and other celebs. The Barack Obamas use it as the nickname for their younger daughter, whose proper name is Natasha. But in line with a trend toward softer-sounding boys' names like Asher and Joshua and thanks to Borat star Sacha Baron Cohen, Sasha also still has life as a boys' name too--it's popular in France for boys and girls almost equally.

Charlie is a friendly, boyish nickname name now used slightly more frequently for girls than boys, with over 2200 baby girls named Charlie last year versus about 2100 boys. That makes Charlie one of the most evenly-balanced and most popular unisex names around today.

Nash is an English surname whose sound puts it right in step with currently trendy names like Cash, Dash and Ash. It first came to prominence via TV character Nash Bridges, portrayed by Don Johnson in the late nineties, and also via mathematician John Nash, played by Russell Crowe in the acclaimed film A Beautiful Mind.

Simple, short, and cool, Ray gives off retro vibes thanks to its 20th century popularity, and its links to jazzy Ray Charles and Ray-Ban sunglasses. A popular middle name for boys, it is well established as a given name too.

A strong Greek name with pan-European charm, Petra is a relatively recent feminization of Peter, though it relates back to an incredible ancient city in Jordan that was rediscovered in the early nineteenth century.

Gia is a cute if slight name that calls to mind stylish sisters Mia, Lea, Pia, Tia, and Nia. One of the most familiar Italian baby names in the US, Gia is a short form of Gianna, which in turn is a diminutive of Giovanna, the feminine form of Giovanni, the Italian equivalent of John—all of them meaning "God is gracious."

Short, sweet, and clear, Lia is used throughout Europe, across America, and in some areas of Asia and Africa, making it a truly international and versatile choice.

Annie is one of the most open and optimistic, the-sun'll-come-out-tomorrow type of name, having been celebrated over the years in song (Annie Laurie), comic strip (Little Orphan Annie), folklore (Annie Oakley, born Phoebe), and film (Annie Hall). It strikes a nice old-fashioned-but-jaunty chord that still has appeal, but we do suggest that you consider putting a more formal version on her birth certificate.

The popular single-named alternative singer (born Bek) has given this cool nature-meets-surname name a new lease of life. Another notable bearer is Beck Weathers, a Texan pathologist who survived the 1996 Mount Everest disaster, which was covered in the book and film Into Thin Air.

A favorite in England and Wales where nicknames as given names are very much the norm, Tilly has the potential to catch on in the US, given its similarity to the popular Lily and Ellie and the rising stars Millie, Billie, Kallie, and Nellie.

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.
