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.

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.

Wilhelmina might once have been condemned as a clunky relic best left in the past, but a steadily increasing number of parents are dusting it off for their 21st century babies. A reasonably popular choice in the 19th century, but out of favor by the 1950s, in the last decade, Wilhelmina has attracted more attention, and was given to around 110 babies in a recent year.

One of the few remaining unrestored vintage gems, with a choice of two winning nicknames--the girlish Winnie and the tomboyish Freddie. Winifred, the name of a legendary Welsh saint, was a Top 200 name into the mid-1920's.

Cecily is as dainty as a lace handkerchief. Cecily has a wide assortment of namesakes. One Cecily was the mother of King Richard III, whose beauty gained her the title "the Rose of Raby," Cecily Parsley is a Beatrix Potter bunny, Cecily Cardew is a character in The Importance of Being Earnest, and the author of the Gossip Girl books is Cecily von Ziegesar.

Mary is the English form of Maria, which ultimately was derived from the Hebrew name Maryam/Mariam. The original meaning of Maryam is uncertain, but theories include "drop of the sea" (from Hebrew roots mar "drop" and yam "sea"); "bitter" (from Hebrew marah "bitterness"); and "beloved" (from the Egyptian root mr).

Helen is a name that has connoted beauty since ancient times – Helen of Troy was the the mythological "face that launched a thousand ships," over whom the ten-year Trojan War was fought.

The name of the sainted mother of the Virgin Mary was among the top girls’ names for centuries, in both the original English Ann spelling and the French Anne. Both left the Top 100 around 1970 but Anne is still among the most classic names for girls, although others are more likely to choose the original Hannah, the Anna variation, or even Annabel or Annabella.

Sleek and serious, yet bright and energetic at the same time, Cynthia appears in classic mythology as an epithet for Artemis or Diana. While it is now a more neglected choice, it was once hugely popular in the middle of the 20th-century, peaking at #7 in the US, and in the Top 20 by diminutive Cindy.

If you love Puritan virtue names and want to move beyond Hope and Faith and Grace, this is a wonderful choice, both for its meaning and its sound. A rare find here, though occasionally heard in England. It was used in Winston Graham's Poldark novels, was Madonna's name as James Bond's fencing instructor in Die Another Day, and made a brief appearance in Harry Potter. Not to mention being a fixture on British and Australian soaps. Verity also appears in one of Agatha Christie's Miss Marple mysteries.

A quaint and quirky flower name, until recently considered a bit too prim for most American classrooms but brought back to life in recent years by the attractive character of Primrose "Prim" Everdeen in the Hunger Games series. In the Top 300 girl names in England and Wales and on Nameberry, Primrose remains rare in the US, but is made more accessible by a raft of sweet nickname options, including Rosie and Posy.

The name of the tragic mythological Trojan princess who was given the gift of prophecy by Apollo, but was condemned never to be believed, Cassandra has been used for striking characters in movies and soap operas. Ethereal and delicate, Cassandra was in the Top 70 throughout the 1990s but is now descending in popularity.

To some, Nancy is a sweet, sparkly, vintage choice with plenty of energy and style. For it strays too much into '"old-lady" territory to be cool again yet. It's out of fashion in France, New Zealand, and Canada; it lingers towards to bottom of the US charts. In the UK however, Nancy has been a Top 100 name for nearly a decade where it fits right in with Evie, Mabel, and Pippa.

A literary name and a place name with a grand yet familiar feel, Virginia has been in the US Top 1000 since records began in the late 19th century. Also familiar in Spain, Brazil and Italy, recent years have seen it rank around the #500 mark in the States.

Its mellifluous sound makes Leonora--which has a rich history and a tie to the popular Leo names-- a keen possibility for revival. Though it's been hiding below the Top 1000 since the 1940s, Leonora is being rediscovered by stylish parents in the US and Europe.

Agatha until recently summoned up visions of martyred saints, mauve silk dresses, and high lace collars, but now that some dauntless excavators have begun to resurrect it, we're sure more will follow their lead. Actor Thomas Gibson used it for his daughter in 2004.

In ancient Rome, Cornelia was considered the paragon of womanly virtue, making it a handsome name with an excellent pedigree. It's rare today, so if you want a name no one else is using, somewhat reminiscent of Amelia and the Shakespearean Cordelia, Cornelia should be on your list. Cornelia's short forms might include Cora, Nelia or Nell--anything but Corny.

Despite her somewhat prissy, puritanical air, Priscilla has managed to stay widely used for well over a century -- it reached as high as Number 127 in 1940 -- appreciated for its delicacy and solid history.

Jemima, the name of a strong and beautiful Biblical daughter of Job, has long been among the chicest choices of aristocratic Brits, and has since shifted to be used more generally too, replacing Gemma/Jemma as a way to nickname "Jem". In a recent year, it featured in the England and Wales Top 500.

Dorothea is a romantic Victorian-sounding name that blends elegance, gravitas and a hint of clunkiness too. Popular in the early decades of the twentieth century, it has been off the charts since 1970, however it's definitely on the brink of a revival! In fact, it has already been making its way back into the UK Top 1000, and a recent year saw it given to 90 girls in the US — three times the number it was given to a decade prior.
