A strong, grounded choice that still has plenty of energy and charm, Leona is the feminine form of Leon, itself derived from the Greek word for "lion". Associated with courage, leadership, and royalty — and the star sign of July and August — Leona is popular in Croatia and Sweden, but familiar across the US, the UK, and continental Europe.

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.

Mavis, another word for the song thrush, is also a relative of the Welsh word for strawberries, mefus. Mavis has something of a British World War II feel, a friend of Beryl and Doris, but it was quite popular in the U.S. a couple of decades earlier, peaking in the Roaring Twenties.

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 .

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.

Constance is one of the more subtle of the virtue baby names, but still has quite a prim and proper image. One impediment to its revival has been the decidedly dated nickname Connie, though modern parents might well opt for using the strong and dignified name in full.

The oldest-known form of Mary, serious and solemn Miriam has been a particular favorite of observant Jewish parents. But we can see it extending beyond that sphere into the next wave of Old Testament names post-Rachel, Rebecca, Sarah, Hannah, and Leah. Miriam is currently the Number 1 girls' name in Israel.

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.

Maude, also spelled Maud, is a lacy, mauve-tinted name that was wildly popular a hundred years ago, but has been rarely heard in the past fifty. Some stylish parents are starting to choose it again, especially as a middle.

Viola has plenty of positive elements going for it: the rhythm of the musical instrument, the association with the flower, the trending 'Vi' beginning and its leading role in Shakespeare's Twelfth Night. With a touch of international flair, it also avoids the violent/Violet some parents have.

Many vowel names stylish a century ago are coming back, and Ida seems like a possible, logical successor to Ada and Ava.

Theodora is one of the most revival-worthy of the charmingly old-fashioned Victorian valentine names, softly evocative but still substantial, as is the reversed-syllable Dorothea.

Minerva is the long-neglected name of the Roman goddess of wisdom and invention, the arts and martial strength, one of the mythology names for girls that might appeal to adventurous feminist parents. With Juno and Jupiter, she made the Capitoline triad, whose worship was at the very center of Roman religion.

Bea is a former old lady name that's cute again as a short form — and is now beginning to stand on its own. Bee is a variation that, like Bea, can work as a diminutive for any name that starts with the letter B, or in the middle. Bea actually stood alone on the popularity lists for four years at the beginning of the twentieth century — and it could happen again.

In the 1930s, Dorothy left Kansas and landed in the Land of Oz; by the '80s she had become a Golden Girl, living in Miami with roommates Blanche and Rose, giving her a decidedly older image. But parents today seeking a quiet classic are bringing Dorothy back—she reentered the Top 1000 in 2011 after almost completely disappearing.

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.

May is a sweet old-fashioned name that hasn't been on the national charts in several decades, but is definitely sounding fresh and springlike. Parents are beginning to see it once more as one of the prettiest middle name options. May was as high on the list as Number 57 in the 1880s; it's now 228 on Nameberry.

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.

This Celtic goddess and Arthurian name may sound terminally old-ladyish to many ears--but so did names like Ella and Etta not so long ago. So Enid is yet another forgotten four-letter E-possibility: she's has been M.I.A since 1954.
