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.
 Popular in the middle ages, Agatha was brought to England at the time of the Norman Conquest by a daughter of William the Conquerer. Agatha is the name of the patron saint of firefighters and nurses, and in more modern times has been closely tied to the period mysteries of Agatha Christie. P.G. Wodehouse created the vivid character of Bertie Wooster's daunting Aunt Agatha.
 Agatha also boasts the cute nickname Aggie. The French version, Agathe, is tres chic there.

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.
 
Agnes, though it was the third most common English girls' name for four hundred years, has long been stuck in the attic. But now it looks like Agnes was so far out it's just about ready to come back in. It did look cute on a little girl in Despicable Me, and nickname Aggie has lots of retro appeal. 
 Agnes has also been making inroads in the celebrisphere—first actress Elisabeth Shue chose Agnes for her third child, and more recently Jennifer Connelly and Paul Bettany named their daughter Agnes Lark. 
 The French pronunciation—ahn-YEZ—could make it more attractive, but few Americans would comply. Other interesting variations: the Welsh Nesta, the Latin/Scandinavian Agneta, the Spanish Inez/Ines/Ynez, and the Scottish Senga—which happens to be Agnes spelled backwards.

With a meaning like "elf power," Alfreda could find some appeal among fantasy enthusiasts. "Freda" makes for a pleasant nickname.

Alfreda

In music, the term allegro means "quickly, lively tempo," which makes this quintessential Bohemian ballet dancer's name all the more appealing. Allegra is one of the most distinctive yet accessible <a href="https://nameberry.com/search/girls-names/a">girl names starting with A</a>.
 One of the most creative sounding of names, Allegra has been associated with the American prima ballerina Allegra Kent, and has been chosen as a first or middle name for their daughters by poets George Gordon, Lord Byron and Henry Wadsworth Longfellow, as well as by R. Buckminster Fuller and Donatella Versace.
Caveat: There is that current connection to the allergy medication.

Archangella

The great philosopher's name is commonly used in Greek families, and is one that could work for daring, philosophy inclined American ones.

Chester is a comfortable, little-used teddy-bear of a name that suddenly sounds both quirky and cuddly.
 Chester was a Top 100 name in the US from the 1880s to 1929, gradually fading till it finally dropped off the list completely in 1995. But it's popular now in England and Wales, where it ranks in the Top 100

Chester has been seen on old TV shows like Gunsmoke and The Life of Riley, then reappeared later on The Nanny and The Wire. Chester Alan Arthur made it presidential, it was a World War II hero via Admiral Chester Nimitz, the comic world associates it with Chester Gould, creator of Dick Tracy, and it has modern musical ties to Chester Bennington, lead singer of Linkin Park.
 Tom Hanks and Rita Wilson have a son named Chester.
 Nickname Chet has, like Hank, a friendly retro vibe.

Star Wars and Harry Potter actor Domhnall Gleeson put this Irish and Scottish name on the international map. Sometimes Anglicized as Donal, its pronunciation is close to Donald without the final d.

Frostine, best known in the U.S. as the name of the Candyland queen, is newly fashionable in France and is certainly a choice that any little girl the world over would love. Fanciful, if over-the-top, but a perfect <a href="https://nameberry.com/list/89/winter-baby-names">name for a winter baby girl</a>.

Frostine

This name of the wife of Mark Antony (no, not Marc Anthony) in ancient Rome sounds a tad too anatomical for a modern girl. 

Fulvia

This variation of Theodore is familiar here mostly via the great Russian novelist Dostoyevsky. It was also the name of three early tsars of Russia.

Has the fusty charm of recently excavated ancient Roman male names like Augustus and Magnus, which might just appeal to the fearless baby namer. 

Horatia

More grown up than Jamie, but never given to more than 13 baby girls in the US per year (and that back in 1968). Modern parents prefer Jamie, Jameson or even James itself, as Blake and Ryan Reynolds chose in 2014.

Lettice is still occasionally heard in upper-class British families, but we fear it would cause too much salad-green teasing to be considered in the U.S.  Calling your little Lettice Lettie could help make the name more user-friendly, or go all the way to the original Letitia.

Libertad is the forceful name recently given to his daughter by Mexican actor Gael Garcia Bernal. English equivalent Liberty has been in use for girls for some time. Libertad might be considered a Spanish virtue name or word name. See our list of other <a href="http://nameberry.com/list/253/spanish-word-names">Spanish word names</a>.

Londyn is now a more popular name than the original London for girls.  Some parents feel that varying the spelling nudges the name away from over-identification with the British capitol. Substituting a y for another vowel is also seen by some as more feminine. For boys, London is five times as popular as Londyn -- though both variations are far more popular for girls.

The association with the infamous Nero, the fiddling Roman emperor, would be unavoidable. But there was also the detective Nero Wolfe, hero of many mystery stories.
 Nero was born Lucius Domitius Ahenobarbus, and Lucius might be a preferable choice if you know anything about ancient Roman history.

Unlike the other fruit names that are just coming onto the baby name menu, Peaches is an old-timey nickname previously reserved for spangled showgirls, and now would be considered an outrageous -- verging on hip -- choice.

Petronilla is an ancient saint's name that relates to the Roman family name Petronius, thought to mean yokel, though some connect it with Petra or Peter, meaning stone.  With the resurgence of so many ancient Roman names, the elaborate and pretty Petronilla or its French form Petronille seem more usable these days than they have in centuries.

Yolanda conjures up visions of midcentury films like "Yolanda and the Thief," complete with gauzy veils, harem pants, and invisible navels. Iolanthe, with the first syllable pronounced the same as in Yolanda, is a softer version, but most modern parents would opt for the English Violet.
