Joan was the perfect name choice for one of the leading characters on Mad Men, being a quintessential girls' name of the period. A Top 10 name in the 30s, a Top 50 name from the 40s through the early 60s, it was the fifth most popular name in the country for three years running and ranks as one of the most common names for girls in the 20th century. But alas, Joan hasn't even appeared in the Top 1000 for a dozen years, and these days it's primarily associated with Joans of the generation of Joan Crawford, Joan Collins and Joan Rivers--just a few of the noted Joans whose ranks also include the singers Joan Sutherland, Joan Baez, Joan Armatrading and Joan Jett. But it's possible that modern parents who are reviving Jane might move on to Joan, inspired by Joan Hollaway Harris.

Natalia was derived from the Latin word natalis, meaning "birthday." It refers to the birthday of Jesus Christ, and thus originated as a name for girls born on Christmas Day. Related forms include the French Natalie, Portuguese Natalina, and Russian diminutive Natasha.

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.

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.

Combine the charming heroine of the movie Legally Blonde with supermodel Elle Macpherson and the trend toward all names beginning with "el"—Ellie, Ella, Eleanor—and you have one hit name.

Liv combines the succinct charm of a nickname—people might assume it's short for Olivia—with the solidity of being a classic stand-alone Scandinavian name with a life-force meaning. It was brought into the public eye (in the English speaking world that is) due to the fame of actress and Aerosmith daughter Liv Tyler.

This a-ending feminine form of Adrian, from the northern Italian city of Adria, is a soft and lovely Italian choice. It appears as a character in Shakespeare's The Comedy of Errors.

Magdalena is a pretty name forever associated with the fallen-yet-redeemed Mary Magdalen; often heard in the Hispanic community. But forward thinking parents are reviving Magdalena along with Magdalene and the unrelated but similar-sounding Marguerite.

Coco came to prominence as the nickname of the legendary French designer Chanel (born Gabrielle) and has lately become a starbaby favorite, initially chosen by Courteney Cox for her daughter Coco Riley in 2004. At first it was the kind of name that the press loves to ridicule, but we predict Coco's heading for more broad acceptance and even popularity.

Ashley was a sensation in the 1980s and 1990s; it hit Number 1 in 1991. Ashley is still pretty but more and more parents are turning to newer names like Ashlyn and Aubrey, and spellings such as Ashleigh and Ashlea. If you hear the name Ashley in a playground today, it's more likely to be the mom than the little girl.

Meadow's upward popularity trajectory certainly suggests that the name has transcended its connection to The Sopranos.. In the US, more than 750 baby girls were named Meadow last year, a number we expect to keep rising.

Despite a rich history in Irish myth preceding its plantation appearance in Gone with the Wind, widespread use in the seventies caused Tara to lose its Irish accent.

Estella is a pretty Latin name, most notably associated with the character in Dickens's Great Expectations, adopted and raised to reek Miss Haversham's revenge on men. With the popularity of Stella, Ella, Esther, and Esme, however, the elaborate Estella has also been making moves up the US charts in recent years.

Joining the likes of Coco and Fifi, Gigi has a style but some may feel it lacks substance. Model and TV personality Gigi Hadid (born Jelena) has likely drawn attention to this name, while designer Cynthia Rowley may have inspired parents to use it as a given name by choosing it for her daughter.

Natasha, an appealing, still unusual name, entered the American mainstream post-Cold War but seems to have peaked in the eighties, replaced by the more straightforward Natalie. As is common for Natashas the world over, the Obamas shorten their Natasha's name to Sasha.

Mona had more than a moment in the sun, peaking in 1950 at Number 230 but falling off the Top 1000 completely in the late 1980s. Its similarity to the word "moaner" undercuts the appeal of its simplicity. In one recent year, fewer than 100 baby girls received the name, and we don't see it reviving any time soon.

Tina, despite its petite and tinkly image, is apt these days to be replaced by the more elegant originals, Christina and Martina.It does have some strong namesakes, though, in Tina Turner (born Anna Mae), Tina Brown (born Christina), Tina Fey (born Elizabeth), and photographer Tina Barney (born Tina).

Cindy as a name in its own right made it into the Top 20 in 1957 and remained a Top 200 girls' name until the end of the 20th century. Although it's fallen precipitously since then and left the Top 1000 completely in 2015, Cindy remains a name commonly heard in the US. Today, though, it would more likely be attached to moms or grandmas than to babies.

Sara, the streamlined form of Sarah, makes this ancient name feel more modern, but perhaps a bit lighter weight.

Originally an English surname, borrowed from the place name, Kendale, Kendall was given almost exclusively to boys until the 40s when it began to be used for a small number of girls each year. By the 80s, it was a gender-neutral choice, however, since the 1993 appearance of the character Kendall Hart in the soap opera All My Children, it has been leaning feminine.
