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.

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.

Gemma is a jewel of a name, an Italian classic that was very popular in 1980s England, but has only recently been started to be used here; it entered the list in 2008.

Emily may have dropped somewhat in the current standings, but it was the most popular girls' name for over a decade because it appeals on many levels: Emily is feminine, classic, simple, pretty, and strong. Emily is Number 1 among Gen Z names. It also has those nice literary namesakes, like Emily Dickinson and Emily Brontë.

Elizabeth is one of the most popular girls' names of all time, the female equivalent of James or William. Yet Elizabeth has so much going for it—rich history, broad appeal, and timeless style—that no matter how many little girls are named Lizzie, Eliza, and Beth, you can still make Elizabeth your own.

Edith was a hugely popular name a hundred years ago that's being revived among stylish parents in Stockholm and London. It's currently beginning to gain traction in the US among those with a taste for old-fashioned names with a soft but strong image.

Melodic and beautiful but with a touch of sass, Calliope is the name of the muse of epic poetry — and perhaps less glamorously, the musical instrument on the merry-go-round. Bold and creative, it debuted in the US Top 1000 in 2016, and in more recent year, IT appeared in the Top 500.

Also spelled as Kalliope — the more traditional Greek transliteration — Calliope means "beautiful voice", making this a musical and poetic choice. It was rarely heard in the US until the 2000s when Calliope "Callie" Torres from the show Grey's Anatomy helped introduce it to a wider audience.

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.

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).

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.

Laura is a hauntingly evocative perennial, never trendy, never dated, feminine without being fussy, with long-standing literary links. All this makes Laura a more solid choice than any of its more decorative counterparts and one of the most classic girl names starting with L.

Flora, the name of the Roman goddess of flowers and spring, who enjoyed eternal youth, is one of the gently old-fashioned girls' flower names that's making a big comeback. Short and sweet, it joins Cora, Florence, Iris, and Ivy in the charts.

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.

Madeline, a lovely name with a soft and delicate image, is an old-fashioned favorite that returned to favor in the 1990s, combining a classic pedigree with a cute nickname option: Maddie.

Lucia is a lush, rich Latinate equivalent of Lucy, popular in Spain and throughout Latin America and also a cross-cultural favorite. You might be surprised to know that Lucia has ALWAYS ranked among the Top 1000 girl names in the US, though she's really taken off only since the turn of this century.

Agnes is the Latin variation of the name Hagne, which itself derived from the Greek word hagnos, meaning "chaste." In medieval times, St. Agnes was a very popular saint, leading to its popularity as a girl's name. Agnes Grey is the title of one of the two novels written by Anne Brontë.

Adelaide is now heading straight uphill on the coattails of such newly popular sisters as Ava, Ada, and Audrey, and in the company of Adeline and Amelia. It was chosen by actress Katherine Heigl for the name of her second daughter.

Bridget is the Anglicized form of Brigid, an Irish-Gaelic name that was derived from the word brígh, which means "strength."

Anastasia is the feminine form on Anastasius, a Greek name derived from the word anastasis, meaning "resurrection." It was a common name among early Christians, who often gave it to daughters born around Christmas or Easter. There are handful of saints named Anastasia, including the patron saint of weavers.

Claudia is a classic name with ancient Roman roots. Never truly in or truly out, Claudia feels like a strong, modern choice that hits the sweet spot between too popular and too unusual..
