This undiscovered unisex name has lots of flair. It was first noticed as a girl's name, starting in the 1980's, on the long-running daytime drama Search for Tomorrow, with the character Adair McCleary, who had ahead-of-their-time brothers named brothers Hogan, Cagney and Quinn. But since Adair has yet to find many takers, it would make a fresh and appealing choice.

Credit the award-winning single-named British singer for taking the <a href="https://nameberry.com/girls-names">girls’ name</a> Adele from a quiet semi-retirement back into currency. Adele reentered the US Top 1000 <a href="https://nameberry.com/popular-names">popular baby names</a> in 2011 and has remained there ever since. 
Adele is both a saint's and a royal name, having originated as the French version of the German Adela. It's one of the most stylish <a href="https://nameberry.com/search/girls-names/a">girl names starting with A</a>. 
Molly Ringwald chose Adele for one of her twins, and Fred Astaire's first dancing partner was his older sister Adele.
 Historically, Adele was the name of the youngest daughter of William the Conquerer. Music lovers might associate the name with a character in Johann Strauss's operetta Die Fledermaus, while a prime literary reference is Jane Eyre's young charge.

Arden, the name of the magical forest in Shakespeare's As You Like It, is a stylish A name with a strong, straightforward image. Another reason to love Arden: its similarity to "ardent." Arden is solidly unisex, with the current gender distribution running about 60 percent girls and 40 percent boys.

 A locational surname name deriving from several places in England, there are multiple legitimate derivations for this name. One is from Old English earn "eagle" + denu "valley", while another is from the Celtic ard meaning "high".

 As a girls' name, Arden has been flirting with the bottom of the Top 1000 in recent years, hopping on and off the US list. A solid Nameberry favorite, this name should begin climbing more steadily.

 Arden is more familiar as a surname, as in cosmetics entrepreneur Elizabeth and actress Eve, and the narrative poem by Tennyson, Enoch Arden. Shakespeare's mother was Mary Arden.

Arden

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.

Avery

Beatrix has a solid history of its own apart from Beatrice, with that final x adding a playful, animated note to the name's imposing history and stately vibe.
 
In the earliest sources it is recorded as Viatrix, meaning "voyager". Possibly the spelling was deliberately changed to resemble the Latin word beatus, "blessed" and now both meanings are part of Beatrix's rich history.
 
It has been largely associated with Beatrix (born Helen) Potter, creator of Peter Rabbit, and with Beatrix who was Queen of The Netherlands from 1980 until her abdication in 2013.
 Actress Jodie Sweetin has a daughter called Beatrix, and designer Kate Spade chose it for her daughter Frances's middle name. The main character in Quentin Tarantino's movie Kill Bill was Beatrix Kiddo, played by Uma Thurman. 
 
With cute nicknames Bea and Trixie, Beatrix is most popular in the UK, where it ranks in the Top 200. On the rise since 2001, its accelerated popularity in the 2010s could have been influenced by the character Beatrix 'Trixie' Franklin from the popular period drama, Call the Midwife.
 
Across the pond in the US, it appeared briefly in the Top 1000 in 2019, but it has been trending downwards since then. Given to around 160 girls each year, it could be an unexpected but familiar choice in the States.

Beatrix

Blythe originated as a nickname for an upbeat person, coming from the Old English word bliðe, meaning "merry" or "cheerful." Today the homophone blithe shares the same meaning. Blythe was eventually adapted to a surname before it became a feminine given name.
 
Blythe embodies a cheerful, carefree spirit and could be the next Blair/Blaine/Blake/Brett/Britt, with the advantage that it's clearly pink. It joins other other light-hearted names for girls: Felicity, Hilary.
 Blythe is the middle name of Drew Barrymore—in her case a surname from her rich theatrical history.
 The title of the memorable Noel Coward play Blithe Spirit is taken from Shelley's poetic line, "Hail to thee, blithe Spirit"—a nice tribute to a baby Blythe.

Blythe

The lyrical and melodious Elodie, a Nameberry favorite, is starting to rise through the US popularity charts for the first time since the 1880s. It's a uncommon member of the trending El- family of names, which includes Ella, Eloise, and Eleanor. 
 
Elodie derives from Elodia, the Spanish variation of Alodia, a gothic German name associated with Saint Alodia. Saint Alodia was a child martyr in 9th century Spain, along with her sister Nunilo. In France, Elodie is spelled Élodie, with an accent over the E.
 
Élodie is a mono-named Italian singer and model as well as a major character in the Emile Zola novel The Earth. Princess Elodie is the protagonist of the video game Long Live The Queen and there was a character on The Hills named Elodie.
 Popular in the UK and French-speaking countries, Elodie could make an original honor name for Aunt Melody.

Elodie

Imogen has long been fashionable in England and is gaining favor in the US among stylish parents. Pronounced the British way — the initial i is short as in Kim, as is the final E as in Ken — Imogen is as pretty and classy as it is distinctive.
 
Though never in the American Top 1000, Imogen may be more popular in your hip neighborhood than that statistic would suggest. A contemporary classic in England and Wales, Imogen has ranked in the Top 100 ever since detailed naming records began in 1996. It's also a Nameberry favorite, consistently among the Top 100 most viewed girl names on our site.
 
The story goes that Imogen originated as a Shakespearean printer's misspelling of the traditional Celtic name Innogen, used by him for a character in one of his last plays, Cymbeline. The Innogen of legend, who Shakespeare’s character was based on, was the wife of Brutus of Troy, the first king of Britain. Earlier versions of her name, including Ennoguent, Innoguend, and Innoguent, were found in Brittany from the 9th-11th centuries. They are probably derived from the Gaelic word inghean, meaning "daughter" or "maiden," and possibly have a connection to the Proto-Celtic word for "white," from which the suffixes -gwyn and -gwen evolved.
 
Even if Shakespeare did happen upon Imogen by accident, he wasn't the first person to use the name. The Latin name Imogenis, meaning "lowest-born," existed centuries before Shakespeare, and was first recorded in the 13th century.
 Imogen gained attention in recent times through its link to Grammy-winning musician Imogen Heap. Other pluses: Imogen has the wonderful namesake photographer Imogen Cunningham and also a meaning that can't be topped. Immy is the cute diminutive; in the book and movie Fried Green Tomatoes, the character Imogene's nickname was Idgie.

Imogen

Lark is getting some new and well-deserved attention as a post-Robin and Raven bird name. Although it was first recorded as a name in the 1830's, it has never appeared on the Social Security list.
 'The Lark' was used as a nickname for Cosette in Les Miserables; Lark Voorhees was a star of Saved by the Bell, and Jennifer Connelly and Paul Bettany used Lark as the middle name of their daughter Agnes.
 
The expression "happy as a lark" gives this songbird name a cheery image, as well as a 'lark' being a synonym for a merry time..
 Larkin is a pretty extension, as is Skylark, which is rich in cultural associations: there's the Percy Bysshe Shelley ode To a Skylark and the jazz classic Skylark written by Johnny Mercer and Hoagy Carmichael..

Lark

A Top 100 name from 1896 to 1921, Leona reached as high as Number 72.
Since then, Leona had seemed to be one of the most unfashionable of the pride of lion names, but singer Leona Lewis has done a lot to rejuvenate it.

Leona returned to the Top 1000 in 2009 after decades of being away. 
 A somewhat more sophisticated option is the French Leontine.

Leona

The lovely Lorelei, a name from old German legend, was a beautiful Rhine River seductress whose haunting voice led sailors to hazardous rocks that would cause them to be shipwrecked. And this siren image clung to the name for ages.
 Lorelei was the name of the gold digger portrayed by Marilyn Monroe in Gentlemen Prefer Blondes in 1953, then went underground for half a century before it was popularized by TV's The Gilmore Girls in 2004.
 The name itself had a starring role in the show, used for the mother, daughter, and even the grandmother. Spelled Lorelai, the characters used three different nicknames: Rory for the daughter, Lori for the mom, and the seemingly unrelated Trix for grandma.
 Beyond the influence of the show, Lorelei is benefiting from the popularity of <a href="https://nameberry.com/search/girls-names/l">girls' names starting with L</a> -- and two Ls are even better than one.

Lorelei

Maeve is a short and sweet name that has become one of the most stylish Irish names for girls in the modern US. Maeve would make an excellent first or middle name choice, with more heft than Mae/May and more modern charm than Mavis. 
 Maeve appears in Irish mythology in two forms, one as the powerful Queen of Connacht, the other as the queen of the fairies. Maeve of Connacht was a warrior queen, famous for starting a war in attempt to steal her ex-husband’s stud bull. Other spellings are Meabh, Medb and Meadhbh, which are connected to mead, a honey-based wine that was produced in many ancient cultures.
 
Chris O'Donnell, Lili Taylor and Kathryn Erbe used Maeve for their daughters. The Irish author Maeve Binchy also is a well-known bearer. Maeve is the name of one of the lead characters on the HBO show Westworld.
 Irish spelling Meabh is popular in Ireland, but not recommended in the US.

Maeve

Maren is one of the many twenty-first-century takes on Mary--but we find the more classic Marin spelling preferable.  When spelled Maren, the pronunciation seems more clearly to resemble Mary, with the emphasis on the first syllable.  Marin, the spelling also used for the beautiful coastal county north of San Francisco, is often pronounced with the emphasis on the second syllable, as in Marie.

Maren

An underused classic that has proved surprisingly unisex over the last few decades, being given to roughly the same number of baby girls and boys in the US from the 1970s to the 2000s. For a girl, Marion has a sturdy old-fashioned charm.

 The meaning of Marie 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).

Marion

Vibrant, sassy, and bubbly, Ruby is a vintage gem that hasn’t lost any of its sparkle. Currently popular in a number of English-speaking countries, Ruby is proof of the 100 Year Rule, trending again for the first time since its heyday in the 1910s. 
The name of a precious stone, Ruby was ultimately derived from the Latin ruber meaning “red”. Despite its sweet, shiny contemporary feel, Ruby has in fact been used as a given name since the 1500s, though it really took off in the Victorian era, alongside Pearl and Opal. 
Many cultures consider rubies to be the stone of kings, and the gem is surrounded by symbolism of wealth, power, life blood, success, and protection. It is also the birthstone for July, which could make it a discreet honor for a July-born relation or just right for a July-born baby. 
In the US, Ruby was a popular choice in the early 20th century, and it peaked at #22 in 1911. By the 1940s however, it was falling down the charts, and while it never left the Top 400, parents turned away from Ruby and to the likes of Judy, Crystal, Rebecca, and Robin instead. 
Then, in the mid-2000s, Ruby made big moves in the UK, leaping to #1 in 2007. Propelled upwards by the catchy song by The Kaiser Chiefs which was released the same year and influenced by celebs such as Tobey Maguire and Charlotte Church choosing it for their daughters, Ruby moved back into the US Top 100 in 2013. 
A truly musical name, Ruby has featured in hits by The Rolling Stones, Cat Stevens, and Kenny Rogers, while namesakes of the fictional and famous variety including Rue from “Euphoria”, Ruby from “Steven Universe”, and Ruby Rose of “Orange is the New Black”, have kept the name in the public eye. 
Given to more than 3000 babies in the US every year and continuing to climb the charts, Ruby is one of those <a href="https://nameberry.com/list/339/vintage-baby-names">vintage baby names</a> that feels totally modern and full of life. 
Love Ruby but want to beat the trends? You could try another vintage gem like Edith, Lula, Twila, Betsy, or Fern, or perhaps something with a similar sound, like Thisbe, Prue, Billie, or Rumi.

Ruby

Rue has gone from Golden Girls actress to Hunger Games heroine to a fresh alternative to beloved middle name Rose. This botanical name is also a coincidental double word name, meaning "regret" in English and "street" in French. Despite these unfortunate secondary meanings, Rue has real potential to be one of the most popular new <a href="https://nameberry.com/list/479/middle-names-for-girls">middle names for girls</a>. 
 It's use in the popular TV series Euphoria has certainly brought it into the spotlight. Since the character of Rue Bennett was portrayed by Zendaya in 2019, the name has been used four times more often than it once was in the US. 
 The herbal plant Rue was introduced by the Romans and has been prized for its medicinal properties – the ancients believed it guarded against epilepsy and vertigo and improved the sharpness of vision.
 
As a name, it has been used as a nickname for Ruth and Ruby, meaning it fits in with vintage nickname options like Bea, Nell, Mae, and Lou, while also matching the style of modern word names such as Wren, Sage, True, and Hart.
 Actress Rue McClanahan, who played Blanche in The Golden Girls, was born Eddi-Rue, named for her parents' middle names Edwin and Rheua-Nell. Actress Sara Rue made her surname the middle name of daughter Talulah Rue.
 
In 2023, Rue was one of the fastest rising names in England and Wales, jumping into the Top 1000 for the first time. In the US, it has also been trending upwards and was given to around 180 girls in a recent year.

Sabrina, the bewitchingly radiant name of a legendary Celtic goddess, is best known as the heroine of the eponymous film, originally played by Audrey Hepburn, and later as a teenage TV witch; it would make a distinctive alternative to the ultrapopular Samantha. Similar names you might also want to consider include Sabina and Serena. 
 In Milton's poem "Comus," the river nymph is addressed as Sabrina Fair, which became the title of a 1953 play. In the original Charlie's Angels, Sabrina was played by Kate Jackson.
 Sabrina debuted on the US popularity charts in 1953, and one year later, with the release of the Audrey Hepburn film, shot up 550 places. It reached the Top 100 in 1977 and hovered in and around the Top 100 until the late 90's when its popularity began to decline.

Sabrina

From the first time we saw the name Saskia attached to a portrait of Rembrandt's wife (her full name was Saakje van Uylenburgh, but she was always called Saskia), we have found it utterly charming and wondered why it hasn't attracted more fans In this country--she's appreciated by the Brits, who have moved her to Number 392. Saskia is one of those names that's been used in Europe since the Middle Ages, but has never crossed the ocean.
 One contemporary bearer is actress Saskia Reeves, who was born to a Dutch mother. Pop artist Red Grooms has a grown daughter named Saskia, and more recently TV's Anne Dudek chose it for her daughter.

Saskia

Although Sylvia seems to be having somewhat of a revival among trendsetting baby namers, we'd still opt for the even gentler and more unusual Sylvie. Despite being dated in its native France (where it was popular during the 1950s and 60s), in English-speaking regions it still feels fresh and international without being unfamiliar and has a cosmopolitan, international air. It debuted on the US Top 1000 in 2016.
 Jason Bateman chose it as the middle name of his daughter Maple. In one of Lewis Carroll's lesser known novels, Sylvie and Bruno, Lady Sylvie is the princess of Fairyland.

Sylvie

Thea is a diminutive of names ending in -thea, including Dorothea, Althea, and Anthea. It is also the Anglicized spelling of Theia, the Titan of sight, goddess of light, and mother of the moon. She was the consort of Hyperion, and mother of Helios, Selene, and Eos. 
 
Whether pronounced THEE-a or THAY-a or TAY-a, Thea presents an appealing artistic image, sensitive and serene.

Thea

Theodora is one of the most revival-worthy of the charmingly old-fashioned Victorian valentine names, softly evocative but still substantial, as is the reversed-syllable Dorothea. 
 
The name Theodora was borne by several saints and by the beautiful ninth wife of the Emperor Justinian, who became the power behind his throne. A later royal was Princess Theodora of Greece and Denmark, the older sister of the late Prince Philip, Duke of Edinburgh. 

 Keith Richards named his daughter Theodora (with whom he recently collaborated on a best-selling children's book) in 1985; Robbie Williams did the same just last year. In TV's Grey's Anatomy Dr. Theodora "Teddy" Altman was a surgeon.

 Theodora offers a menu of neat nicknames, from the classic Teddy to trendy Thea to the vintage Dora. Theodora also has some cool international variations as well: Theodosia, Feodora and Teodora. It reentered the US Top 1000 in 2019 for the first time in over 60 years and seems destined to follow brother name Theodore toward the top of the list.

Theodora

Fresher, brisker and, yes, cooler than Summer or Autumn or Spring, Winter is now a full-fledged female choice, especially since Nicole Richie and Joel Madden used it for daughter Harlow's middle name, and Gretchen Mol picked it as her daughter's first, as did media mogul Sean Parker. Winter continues to be the preferred spelling and has risen in popularity significantly over the past few years.
 Although Winter entered the U.S. Top 1000 in 1978, it was been used as a first name as early as the seventeenth century.
 Some interesting international words for winter: Aeneva (Cheyenne, Native American), Cole (Chinook, Native American), Hima (Sanskrit), Jara (Hindi), Saradi (Hindi), Vandi (Kashmiri), Zaya (Old Persian) and Zima (Russian, Bulgarian).
