An aristocratic and stately Germanic route to the popular Leo, Leopold is a royal name: Queen Victoria used it to honor a favorite uncle, King Leopold I of Belgium. These days, this royal tie may be seen as a drawback to the name, owing to the cruelty of King Leopold II's rule over the Congo, though it remains popular in Austria, Poland, and France (as Léopold).

Seraphina is one of the most-searched name on Nameberry, destined for even greater popularity. The highest-ranking angels, the six-winged seraphim, inspired the lovely name Seraphina.

Florence is back, returning to the US Top 1000 girl names in 2017 after a nearly 40 year absence. Other English-speaking countries have been quicker to welcome Florence back into fashion.

Thanks to the surprise hit revival of Etta James' song At Last and because of recent interest in vintage style nicknames, Etta has established herself as a possible successor to Emma and Ella. While it is currently in the latter end of the US charts, the smart, snappy name is a rising choice in the UK, where it features in the Top 150.

Birdie was until recently a middle-aged Ladies' Club member wearing a bird-decorated hat --but now it's just the kind of vintage nickname (think Hattie, Josie, Mamie, Millie) that's coming back into style in a big way. Actress Busy Philipps named her baby Birdie (inspired by First Lady Lady Bird Johnson), as did soap star Maura West.

Rufus is a rumpled, redheaded (it was the nickname for red-haired King William) ancient Roman name popular with saints and singers (e.g. Rufus Wainwright); now, Rufus is on the cutting edge of cool.

Rupert is a charming-yet-manly name long more popular in Britain (where it's attached to a beloved cartoon bear) than in the U.S. Yet we can see Rupert as a more stylish, modern way to honor an ancestral Robert.

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.

Can Linus lose its metaphorical security blanket and move from the Peanuts page onto the birth certificate? We think it has enough charm and other positive elements going for it for the answer to be yes.

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.

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.

A "modernization" of Leonora that has suddenly come back on the radar along with the many other Leo names--both male and female. With literary cred via a famous eponymous poem by Edgar Allan Poe (and also in his even more famous The Raven,) Lenore was steadily in the top half of the popularity list until the mid-fifties, falling off in 1973. Cameron Diaz played a Lenore in The Green Hornet.

Just as Seamus/Seumus is Irish for James, Hamish is the Scottish form — one that's not often used here, but still redolent of Olde Scotland. If you're ready to go further than Duncan and Malcolm, out to Laird and Ewan territory, this may be worth consideration. It also sounds just like the Yiddish word for homey.

In Celtic lore, Fergus was the ideal of manly courage, making it a charming, slightly quirky Scottish and Irish favorite.

The ultimate Jane Austen hero name, Darcy makes a handsome, surname style choice. Predominantly used for girls in England and Wales, across the pond in Australia, it is a stylish Top 100 name for boys. In the US meanwhile, it does lean feminine, however, 30 boys were given the name in a recent year, suggesting it is on the up across the board.

There are several Percivals scattered through the Harry Potter series, which might help transform the old-fangled, fussy image it has accrued. Actually, the original Percival was the one perfectly pure Knight of the Round Table, a worthy hero. The name was invented in the twelfth century by a poet named Chretien de Troyes, for his ideal knight in the poem Percevale, a Knight of King Arthur.

Barnaby, a genial and energetic name with an Irish-sounding three-syllable lilt, is an ancient appellation that manages to be both unusual and highly attractive and deserves to be used more than it is. A sweet-spot name that's a real winner.

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.

Philippa is a prime example of a boy's name adapted for girls that was common as crumpets in Cornwall, but rarely heard stateside. That was before the advent of royal sister-in-law Philippa Middleton, who goes by the lively nickname Pippa.
