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).

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.

Serene Irene, the name of the Greek goddess of peace and one of the most familiar Greek goddess names, was hugely popular in ancient Rome and again in the United States a hundred years ago.

Victoria is the Latin word for "victory" and a feminine form of Victor. It is the name of the ancient Roman goddess of victory, the equivalent of the Greek Nike, and also a popular third century saint.

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.

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.

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.

Tove is a modern variation of an Old Norse name for which there are no letters on the twenty-first century keyboard (Þórfríðr, for those interested.) Surviving and thriving in modern Scandinavia in the form of Tove, Tuva, and Tova, it is originally related to the name Thor and means "beautiful, beloved."

As a highly popular girls' name in all Spanish-speaking countries, this saintly Latin variation of Mary retains a timeless beauty. Through the centuries, Maria remains one of the most widely-used girl names starting with M.

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.

With its relation to Mount Olympus, home of the Greek gods, and to the Olympic games, this name has an athletic, goddess-like aura, making it the perfect Olivia substitute.

Though it sounds like a chopped-off variation of Olivia, which means olive, the distinctively attractive Livia has been an independent name since the days of the ancient Romans, when it belonged to Livia Drusilla—the powerful wife of the Emperor Augustus—and is still commonly heard in modern Italy.

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.

A saint's name with a noteworthy literary background, including uses by Shakespeare in Two Gentlemen of Verona and Much Ado About Nothing, by Ben Johnson, Walter Scott, Longfellow, D. H. Lawrence and Neil Gaiman. In real life, her two most well known representatives are writer Ursula Le Guin and actress Ursula Andress. In literature, there is also Ursula Iguaran, a key, long-lived character in Gabriel Garcia Marquez's major work, One Hundred Years of Solitude.

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.

With Isabel getting so popular, parents are searching for new varieties of the name, and Isabeau is one that makes a lovely French twist.

Christina, a pretty and feminine, crystal clear classic, may be trending downward, but it's never out of style and its extra syllable does keep it fresher feeling than Christine. Christina's short forms Chris, Christie, and Tina might seem date to some — but used in its full form, it possesses the strength and elegance of Diana, Josephine, and Ophelia.

A soft and interesting Hebrew name long popular in France, where it has ranked in the Top 400 since 1986 (as Salomé). Ex-ER star Alex Kingston named her daughter Salome Violetta.

Antonia is stronger than most feminized boys’ names, reflecting the pioneer spirit of Willa Cather's classic novel My Antonia. Antonia is hovering near the bottom of the US popularity list, which may be an excellent reason for you to use it.

A classic name with regal elegance--Queen Victoria, like other queens, had Regina appended to her name. She was a Top 100 name in the 1960s.
