Aurelia is an ancient Roman name that's become a surprise hit in the contemporary world. A top favorite on Nameberry, it reentered the US Top 1000 in 2014 after a 70-year absence and continues to climb.

Lydia is one of the first place names, after an area of Asia Minor whose inhabitants are credited with strong musical talent great wealth. Always among the US Top 1000 girl names, Lydia is a quietly fashionable classic.

Caroline is a perennial classic, one of the elite group of girls' names that's ALWAYS ranked among the Top 1000 and that's been in the Top 100 since 1994. Elegant yet strong, Caroline calls to mind the Kennedy Camelot years and Princess Caroline of Monaco.

Frances, a soft and gentle classic last popular a hundred years ago, is trending again. The cool nickname Frankie is one reason for the revival of Frances, adding lightness and sass to a serious name. Frances is the feminine form of Francis, the English variation of the Latin name Franciscus. Franciscus, meaning "Frenchman," was taken from the Germanic tribe the Franks, which got its name from the francisca, the axe they used in battle. Until the seventeenth century, the spellings Frances and Francis were used interchangeably for both sexes.

Margaret is derived from the French Marguerite, which in turn came from Margarita, the Latin form of the Greek Margarites. Margarites was based on the Old Persian word margārīta, meaning "pearl."

Felicity is as accessible a virtue name as Hope and Faith, but much more feminine -- and dare we say, happier. The hit TV show did a lot to soften and modernize the once buttoned-up image of Felicity, and it got further notice as the red-haired Colonial doll, Felicity Merriman, in the American Girl series. A current bearer is actress Felicity Huffman.

June, a sweetly old-fashioned month name derived from the goddess Juno, was long locked in a time capsule with June Allyson (born Ella) and June Cleaver, but is rising again especially as a middle name.

Louisa, a quaint but strong vintage name, might feel fresher in English speaking countries than old favorite Louise, just as Diana and Julia have more energy than Diane and Julie at the moment. Part of this might just be that Louisa has never been so popular as Louise, so it makes a familiar but distinctive option alongside Eloise, Lucy, Luna, and Lucia.

Helena is one of those classic names that just misses making the US Top 1000 girl names for its entire history, falling off for a single year in 1992. Since then it's been drifting lazily up the charts, and makes a perfect choice if you want a name that both fits in and stands out.

Sarah was derived from the Hebrew word sarah, meaning "princess." Sarah is an Old Testament name — she was the wife of Abraham and mother of Isaac. According to the Book of Genesis, Sarah was originally called Sarai, but had her name changed by God to the more auspicious Sarah when she was 90 years old.

The musical, sylvan Sylvia seems poised to join former friends Frances and Beatrice and Dorothy back in the nursery.

Lavinia is a charmingly prim and proper Victorian-sounding name which actually dates back to classical mythology, where it was the name of the wife of the Trojan hero Aeneas, who was considered the mother of the Roman people.

Diana, the tragic British princess, inspired many fashions, but strangely, not one for her name. For us, Diana is a gorgeous and still-underused choice.

Harriet has long been considered a stylish, upscale name in England, but it's still waiting to be revived in the US—though some parents seeking a solid, serious semi-classic are beginning to consider it.

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).

Linnea is an attractive Scandinavian name that derives from the renowned 18th century Swedish botanist Carl Linnaeus, who developed the Linnean system of classifying plants and animals.

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.

The name of our first First Lady still has something of a prim and proper image, academic and efficient. That quiet, traditional, and tasteful gestalt is exactly what makes Martha appealing to some parents today.

Susannah is by far the most stylish form of the classic name now that Susan and Suzanne have retired. Susannah has biblical and musical pedigrees, is impervious to trends, and has an irresistible, flowing rhythm. It can be spelled just as properly with or without the final 'h.'

Despite a return to such feminizations of male names as Josephine, Clementine, and Theodora, starchy Henrietta has not made it into that group. Still, if you look hard enough, you'll see that Henrietta has the same vintage charm.
