Simple, classic, strong, and versatile, Jane has shrugged off her plain associations to become a short, punchy name with plenty of literary significance. Calling to mind Jane Austen and Jane Eyre, this charming choice is in the Top 300 in the US and The Netherlands, but a currently underused option elsewhere.

Bonnie is an adorable nickname name, heading back up the popularity list after a 50-year nap. A Top 100 girls' name throughout the rest of the English-speaking world, Americans are later to jump on the Bonnie bandwagon but now it's trending here too.

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).

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

For a long time, Isadora has been overlooked in favor of Isabella, owing perhaps to its association with the tragic modern dancer, Isadora Duncan, or because parents would rather their daughter be a Bella than a Dora. Now, with Theodora back in the charts and vintage names in vogue, Isadora has been slowly gaining more attention over the last decade.

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.

Esther was derived from the Old Persian word stāra, meaning "star." In the Old Testament, Esther, originally named Hadassah, was the captured Jewish wife of the King of Persia who risked her life to save her exiled people from annihilation. This story is celebrated by Jews on the holiday of Purim, so that it has traditionally been given to girls around that time.

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.

The image of the lovely Lady Sybil, tragic youngest daughter of the Crawley family on Downton Abbey is likely to go a long way towards reviving this almost forgotten name, off the list since 1966 and most popular in the 1920s and '30s.

The name of a martyred medieval saint, Valerie has been on the popularity list since its earliest publication in 1880. Though it peaked in the 1960s, remaining in the Top 100 until 1988, it still doesn't sound terminally dated; the association with the word valor gives it a sense of boldness and makes it one of the special group of girl names that mean strong.

Ruth, with its air of calm and compassion, was the third most popular name in the 1890s, remaining in the Top 10 through the 1920s. It's still in use today as some parents tiring of Rachel and Rebecca are giving Ruth a second thought. Some see such Old Testament girls’ names as Ruth and Esther rising on the heels of boy equivalents Abel and Moses.

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

The name Veronica projects a triple-threat image: at once saintly, sensuous, and strong. The name derives from Berenice, the Latin form of the Greek name Berenike "she who brings victory", with the spelling influenced by the Latin phrase vera icon "true image". Veronica was the name of the compassionate woman who wiped Jesus's face when he was on his way to Calvary and whose cloth was miraculously imprinted with his image: she is now the patron saint of photographers.

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.

Simone, the elegant French feminization of Simon, strikes that all-important balance between unusual and familiar, and it's oozing with Gallic sophistication. A dated choice in its native France, gymnast Simone Biles brings new bounce and spark to name.

Ramona is a sweet spot name – neither too trendy nor too eccentric. Kids will associate it with the clever Ramona Quimby character in the series of books by Beverly Cleary, also seen on TV. It was chosen by starcouple Maggie Gyllenhaal and Peter Sarsgaard for their little girl, who would be joined by sister Gloria.

The luminous Ingrid Bergman's appeal was strong enough to lend universal charisma to this classic Scandinavian name, which has been somewhat neglected in the US. Even today, a child named Ingrid would be assumed to be of Scandinavian ancestry, signaling the name has never been fully integrated into the English lexicon the way other European choices from the same era like Danielle or Kathleen have.

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 .

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.

Although Susan had her heyday from the thirties to the sixties, and is now common among moms and new grandmas, and though most modern parents would prefer Susanna/Susannah, we have spotted some flickers of interest in a revival. It still retains a certain black-eyed-Susan freshness.
