Newly fashioned but familiar and with an on trend, unisex feel, Addison seems like the perfect solution for anyone who can’t decide between Madison, Adeline, and Alison. 
Addison really took off in the mid-2000’s, making a spectacular jump from being outside the Top 100, to being nearly within the Top 10, just two years later. Undoubtedly influenced by the introduction of Dr. Addison Shephard to “Grey’s Anatomy”, the name was at its peak in 2009. 
While it’s been steadily falling back down the charts, it does remain a popular choice. Currently given to nearly 4000 girls in the US each year, it ranks highly in New Zealand and Canada too. In the UK, it has made significant gains, becoming familiar for girls – and for boys too. 
Borrowed from an English surname, meaning “son of Adam,” Addison joined Madison as one of the few “son of” names to be used almost exclusively on girls. It also joins the 17 strong crowd of “Ad- names” in the charts for girls, including Adeline, Adelyn, and Adelaide. 
Contemporary and cool with a cute, sassy nickname, Addison has been a popular choice for celebrities. Baseball player Jason Bay, TV personality DeAnna Papas Stagliano, NASCAR driver Sam Hornish Jr, and Joe and Kendra Duggar all have daughters called Addison. 
It is unclear if Addison will fall as fast as it rose, but for now it remains comfortably within the Top 100. So, if love Addison but want your choice to stand out, you could try: Sullivan “Sunny”; Halliday “Hallie”; Barrett “Betty”; or Alcott “Lottie.”

Adeline has a lovely, old-fashioned "Sweet Adeline" charm, but has become so popular in the US under so many spellings and variations -- with Adalynn and Adalyn also popular -- that considered together it is far more popular than it first seems. Adorable nickname Addie is also pervasive. 
Adeline originated as a French diminutive of Adele, which came from the Germanic root adal, meaning "noble." Adeline was introduced to England by the Normans in the eleventh century, was very common during the Middle Ages, then vanished until the Victorian Gothic revival. Common variants of Adeline include Adalynn, Adalyn, Adelyn, Adelynn, Adelina, and Adaline.
 Adeline was introduced to England by the Normans in the eleventh century, was very common during the Middle Ages, then vanished until the Victorian Gothic revival.
 The song "Sweet Adeline" Is an old barbershop quartet favorite. JFK's grandfather John F. Fitzgerald, mayor of Boston, made it his theme song, and Mickey Mouse serenaded Minnie with it in a 1929 cartoon.
 Pronounced ad-a-line in America, it's usually ad-a-LEEN in France.

Adeline

Old Irish name that's taken off in its Anglicized forms, mainly Ashlyn or Ashlynn. Nonetheless, this more traditional version debuted in the US Top 1000 in 2015.

Amelia is one of the hottest <a href="https://nameberry.com/girls-names">girls' names</a>, a successor to the megapopular Emma and Emily. Amelia, which spent several years at Number 1 in England, vaulted into the US Top 10 in 2017 and continues to rise.
 
Now the most popular <a href="https://nameberry.com/search/girls-names/a">girl name starting with A</a>, Amelia is also a Top 10 girls' name in Australia, Ireland, New Zealand, Scotland and Poland. So while Emilia and Emelia are sound-alike names, it's the Amelia version that's on the fast track. 
 
Amelia is derived from the German name Amalia, which in turn is a variation of Amalberga. The root, amal, is a Germanic word meaning "work," and in the context of female given names suggests themes of fertility as well as productivity. Aemilia, the name from which Emily is derived, is unrelated to Amelia.
 
Kids might associate Amelia with the wacky children's book character Amelia Bedelia, while adults could appreciate it as the eponymous heroine of the Henry Fielding novel. Amelia also appears in novels by Trollope and Thackeray, as a Harry Potter name, and as detective Amelia Peabody in the Elizabeth Peters series. Angelina Jolie played patrol cop Amelia Donaghy in The Bone Collector.
 
Amelia became a British royal name via the daughters of Kings George II and III. American heroes who have inspired a new generation of namesakes are aviatrix Amelia Earhart and feminist Amelia Bloomer.
 
Trivia tidbit: Amelia is the birth name of Minnie Driver.

Amelia

Arya was derived from an Indo-Iranian word meaning "Aryan" or "noble." It is a masculine given name in Iran, Indonesia, Bali, and Sanskrit-speaking regions of India. In Hindu- and English-speaking parts of the world, Arya is more often a feminine name, the latter influenced by the similar Italian name Aria, meaning "air" or "song."
 
The prime impetus of Arya's rise is the fiercely independent young character Arya Stark in the TV series Game of Thrones, based on the George R. R. Martin books A Song of Fire and Ice. Another influence is the Elven princess in Christopher Paolini's Inheritance Cycle trilogy, basis of the movie Eragon. 
 
The name resembles the musical Aria and the male Aryan, both also growing in popularity in the US. Arya entered the popularity charts in 2010.

Arya

Avery is a hugely popular name in the US, especially for girls. But while nearly four times as many girls as boys are named Avery today Avery's popularity is starting to soften for girls while it continues to strengthen for boys.

Unlike many gender-neutral surname-y names popular today, Avery began life as a first name and later became a patronymic last name. It originated in the Middle Ages as a Norman-French pronunciation variation of the Anglo-Saxon name Alfred and the Ancient Germanic name Alberich. The elements aelf, meaning "elf" and ric, meaning "ruler" give Avery its meaning. 
 
Angie Harmon and Jason Sehorn may have started it all when they chose it for their daughter in 2005, just as they did with daughters Finley and Emery. Amy Locane used the name in 2009 and now Dr. Phil has a granddaughter named Avery.
 
On 30 Rock, Elizabeth Banks had an extended cameo playing Alec Baldwin's glamorous fiancée, Avery Jessup.

Clara is a strong, lovely girls' name that's always ranked among the US Top 1000 girl names but has been climbing since the turn of this century. Now holding steady around Number 100, Clara is a modern classic, neither too popular nor too unusual.
 
Long relegated to an Olde World backwater, the European-flavored Clara was long less fashionable than sleeker sister Claire. Now, though the vintage chic Clara is still less popular, it's arguably the more stylish of the two names. 
 Clara was a Top 10 name in the 1880's, at one time associated with the silent screen 'It Girl,' Clara Bow, and before that with German musician and composer Clara Schumann and Red Cross founder Clara Barton, who was born Clarissa.
 Clara is beloved for her leading role in The Nutcracker ballet and as Heidi's invalid friend. Actor Ewan McGregor was an early celebrity adopter of the name for one of his daughters.
 Other Clara variations you might want to consider include Clarissa and Clarina, though Clarabelle seems still fit mainly for cows.

Clara

Constance is one of the more subtle of the virtue <a href="https://nameberry.com">baby names</a>, 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.
 One of William the Conqueror's daughters was named Constance, and in Shakespeare's King John, Constance is the devoted mother of King Arthur. Constance was widely used in the seventeenth century by Puritans: Constance Hopkins was a young passenger on the Mayflower.
 The fictional Constance Billard School appears in TV's Gossip Girl, and Constance was the first name of the decidedly non-prim and proper Lady Chatterley.
 Oscar Wilde's wife was Constance, and Mozart's spouse was the German form Constanze, nicknamed Stanzi.
 Though Constance has been neglected here for a number of years, it's still ranks at Number 120 in France.
 Trivia tidbit: Constance was the birth name of 1940's peekaboo-hairdo star Veronica Lake and also, not surprisingly, Connie Britton.

Constance

In Greek mythology, Daphne was the nymph daughter of Peneus, a river god. Peneus saved Daphne from Apollo’s romantic obsessions by transforming her into a laurel tree. It is from this myth that the plant genus daphne, which contains the laurel species, gets its name.
 
Daphne's origins may be Greek, but it's seen by Americans as quintessentially British—as in the Daphne Moon character on Frasier and the heroine of the new romantic drama Bridgerton. The shrub inspired the popularity of the name in England, where it became part of the British vogue for plant names at the end of the nineteenth century. 

Though we don't see it becoming a Top 100 name in the US, Daphne is obviously finding more widespread acceptance—and for a distinctive, deeply-rooted, attractive girls' name, that's a positive thing. In fact, Daphne has been in the US Top 1000 for every year but two -- 1913 and 1938 -- since 1880, the first year the US government recorded baby names. And it's now at its highest point since the 1960s.
 Its most famous bearer is Daphne du Maurier, author of such suspense novels as Rebecca. Fictional Daphnes have appeared in Some Like It Hot (Jack Lemmon as a woman), The Jewel in the Crown, Scooby-Doo, Harry Potter, and Heroes.

Daphne

Both Elaine and Elena are on an upward trajectory, which means that Elaina, a combination of the two, is popular too.

Whichever way to spell it, this traditional variation of the classic Helen is appealing and has a lovely meaning. Another variation on the way up: Alayna.

Short form Lainey is popular in its own right, but can also work as a nickname.

Elaina

Emmeline is an Emma relative and Emily cousin that is destined for greater use in the wake of the megapopularity of those two names. A recommended Nameberry fave, Emmeline hopped onto the US Top 1000 in 2014 for the first time ever. While it is genuinely an old name, it was rarely used a century ago; only 17 baby girls were named Emmeline in 1915, the same number as were named Ernie!
 A popular medieval name, Emmeline was introduced to Britain by the Normans. It appeared as a character in Uncle Tom's Cabin, and is famous in Britain as the name of the illustrious suffragette, Emmeline Pankhurst. Way back in 1980, it was the name of young Brooke Shields's innocent character in The Blue Lagoon. More recently, Emmeline Vance was a witch in the Harry Potter series.
 Christian Bale has a daughter named Emmeline.

Emmeline

Faith is one of the most straightforward of the virtue names popularized by the Puritans in the seventeenth century, many parents still choosing it as an indicator of their religious conviction. Faith peaked in 2002 at Number 48.
 Nicole Kidman and Keith Urban are the parents of a daughter they called Faith, little sister for Sunday -- a sibset suitable for a minister's brood. A prominent adult bearer is country singer Faith Hill.

Faith

Because of Gwyneth Paltrow, this has almost become a one-person name, but not in the prohibitive there's-only-one-Oprah sense. Also seen as Gwenyth and Gweneth, this mellifluous appellation is definitely becoming more and more appreciated by American parents-- enough to land it on this year's Top 1000.
 Gwyneth is an Anglicized form of Gwynedd, the name of an ancient Welsh kingdom. Gwyneth Jones is an acclaimed Welsh Wagnerian soprano.

Gwyneth

Isabel derived from Elizabeth in southwest Europe during the Middle Ages. It was originally written as Elisabel, but the first syllable was dropped as it spread across the continent. In Spain and Portugal, Isabel and Elizabeth are considered to be variations of the same name, but they are treated as separate names in other European countries and the US.
 
The charming Isabel is hugely fashionable again, a century after its first wave of success. And it's easy to see why: it's ladylike (a la Isabel Archer in Henry James's Portrait of a Lady) and melodic, traditional yet slightly offbeat. Isabel sounds smart as well as pretty. 
 Two noted cultural namesakes are Chilean author Isabel Allende and painter Isabel Bishop, as well as Cuban-American fashion designer Isabel Toledo.
 The only downside: with Isabella's recent popularity, there are so many other little Isabels, Isabelles, Isabellas, Belles, and Bellas, yours would be far from unique.
 The Office's Angela Kinsley named her baby girl Isabel, and Annette Bening and Warren Beatty have a teen-aged Isabel.
 Isabelle is the French version, Isabella the Italian one, and Isobel the Scottish spelling, which has a definite character of her own, the 'o' giving her an extra infusion of strength. 
 Nifty nicknames include Izzy, Ibby, Isa and Belle.

Isabel

Jocelyn has gotten new life and popularity as a result of the current passion for lyn endings. Though it was a male name in medieval times, now Jocelyn couldn't sound more softly feminine.
 John Galsworthy's 1989 novel Jocelyn is part of his Forsyte Saga. Singer Joss Stone's birth name was Jocelyn.
 Jocelyn would make a pretty namesake name to honor a Grandma Joyce.

Jocelyn

Upside: it has an interesting ancient look and feel, related to the Roman family name Laelius of uncertain meaning.  There is also a type of orchid called the Laelia.  Downside: possible confusion with all those Laylas, Lailas, etc. out there.

Laelia

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. 
 Livia was a literary favorite from the sixteenth century, appearing in the plays of John Fletcher and Thomas Middleton, and playing a minor role in Romeo and Juliet. Anna Livia Plurabelle is the name of a character in James Joyce's Finnegans Wake.
 Livia entered the US Top 1000 in 2004 but unlike its popular sister Olivia, it's never risen that high in the ranks. But Livia is a Top 100 girls' name in many other countries, including France, the Netherlands, Brazil, Sweden, Switzerland, and Austria.

Livia

Singer Macy Gray has popularized this cute and upbeat choice—once solely associated with the department store—a modern replacement for Stacy and Tracy. 

Macy

Madelyn is the most popular current spelling of this stylish name -- Madeline is the second most used -- but we prefer the least popular and most authentic French version, Madeleine, which ranks third.

The advantage of Madelyn: It does clarify pronunciation and may be the best choice if you definitely want that last syllable pronounced as "lynn".

The disadvantage of this name, however you spell it: Its mega-popularity when all spellings are considered together. Roughly 10,000 baby girls were given some version of the name Madelyn in the US last year, making it equal to a Top 10 girl name.

Madelyn

Neige

Olivia, a lovely Shakespearean name with an admirable balance of strength and femininity, is the Number 1 name for baby girls in the US and one of the top girls' names around the world. 
 
Olivia ranks among the Top 10 girls' names in several English-speaking countries as well as in Spain, Belgium, Norway, Denmark, Finland, the Netherlands, and Argentina. And it's a Top 100 name in most countries that keep baby-naming statistics, making it an internationally flexible choice. 
Records of the name Olivia exist from as far back as 13th century England, but the name was popularized after Shakespeare used it for the name of the countess in Twelfth Night. Olivia is based on the Latin word oliva, meaning "olive." In ancient Greece, the olive was a symbol of Athena as well as a token of peace and fertility, and olive wreaths were awarded to the winners at the Olympic games. 
 
Olivia has been a popular celebrity baby name for fifteen years, and has also been a well-used TV character name, such as in Olivia Benson on Law & Order SVU and the recent powerful lead Olivia Pope on Scandal.
 
Golden Age star Olivia de Havilland was influential in bringing the name to U.S. attention, followed by Olivia Newton-John, and now we have Olivias Wilde, Munn, Rodrigo, Colman and Williams.
 If you love <a href="https://nameberry.com/popular-names">popular names</a>, Olivia might be the perfect choice for you, but parents in search of a distinctive name will have to keep looking. Some related alternatives: Olive, Livia, Liv.

Olivia

Quinn is the Anglicized version of the Irish patronymic surname Ó Cuinn, meaning "descendent of Conn." Conn has two possible derivations—the Old Irish cond, meaning "intellect," or cenn, meaning "chief." One of the most notable Quinn clans was from County Tyrone in Northern Ireland. 
 
Quinn is one of the first Irish unisex surnames, a strong and attractive choice on the rise for both genders, though there are now far more girl Quinns than boys. 
 Quinn started taking off for girls in the mid-nineties, possibly influenced by the popular show Dr. Quinn, Medicine Woman. Since then, there have been female Quinns on the animated MTV show Daria, on Zoey 101, and—most prominently—on Glee, featuring cute blond cheerleader character Quinn Fabray.
 Some other, more <a href="https://nameberry.com/lists/category/unusual-names">unusual names</a> with the Q-factor: Quincy, Quintina, Quintana, Quinta, Quilla--and, on a different note, Queenie.

Rhya is the Fertility Goddess of several ancient religions, associated with mothers and pregnant women. In some legends she is the mother of Manann and Verena and wife of Taal. Pronounced rye-ah, similar names from other cultures include Rya, Riya, and Raya.

Rhya

Peaceful, calm, and untroubled: these are qualities parents may be hoping for, either on their parenting journey or in their child’s life. The name Serenity encapsulates these hopes, conjuring up a sense of balance, composure, and ease. 
A virtue name of Latin origin, Serenity means “peaceful” or “tranquil.” The pretty, melodic sounds reflect that, but it isn’t a meek or retiring name; it has plenty of flair too and a hint of breezy confidence. 
Used occasionally from the 70’s onwards, Serenity entered the US Top 1000 in 1997, and by 2009, it was in the Top 100, where it has stayed ever since. 
While recent years have seen it begin to drop back down the charts, it has fared better than its once popular virtue cousins, Destiny and Trinity. Given to nearly 3000 girls every year, it remains in the Top 100 for now. 
Notable pop culture references for Serenity include a character in the Sailor Moon franchise and the title of the 2005 movie spinoff of the TV show, Firefly. 
If you like the vibes of Serenity but worry about the expectations it brings with it (or just concerned it will guarantee that your child is the least tranquil child to ever exist), then you could consider the less wordy and more international variant, Serena. 
You could also take a look at <a href=“https://nameberry.com/list/411/baby-names-that-mean-peace”>names that mean peace</a> but aren’t in your face about it, such as Irina, Shiloh, or Fenna.

Yes, Spencer makes a plausible and powerful female choice these days, though still thought of as primarily for boys. Kelsey Grammer used it for his daughter in the 1980's. Spencer made its first appearance on the girls' Top 1000 in 2017.


Spencer

Inspirational, aspirational word name that would work especially well as a middle name; it was used by Forest Whitaker for his daughter, and more recently by Khloe Kardashian.

If you love Puritan virtue names and want to move beyond Hope and Faith and Grace, this is a wonderful choice, both for its meaning and its sound. A rare find here, though occasionally heard in England. It was used in Winston Graham's Poldark novels, was Madonna's name as James Bond's fencing instructor in Die Another Day, and made a brief appearance in Harry Potter. Not to mention being a fixture on British and Australian soaps. Verity also appears in one of Agatha Christie's Miss Marple mysteries.
 We love the newer sounding three-syllable, 'y'-ending virtue names, and Verity is one of the best.
