Adeliza is a unique member of the popular Adelaide-Adeline family. Different enough to distinguish it from all the others? Maybe, and it's definitely got an appealing sound that makes it sound a bit like a smoosh of Adele and Eliza.

Adeliza

Aida is a melodic name largely associated with the title character of the 1871 Verdi opera, an enslaved Ethiopian princess who dies to save her people. In the past, her name was rarely heard outside the Latino community, but in the current time of love for all A-starting girls' names, this could very well change.
 Aida did have a period of some U.S. popularity; in 1954, it reached as high as Number 663, but fell off the list in 1976. Aida Turturro played Tony Soprano's sister in The Sopranos.

 Arabic families often pronounce it with two syllables — as EYE-dah — rather than three.

Aida

Ailsa is a traditional <a href="https://nameberry.com/list/472/scottish-names-for-girls">Scottish name for girls</a> related to a rocky island in the Firth of Clyde called Ailsa Craig. It might make an interesting alternative to the outdated Ashley or overly popular Ella, and could also be thought of as a relative of Elizabeth or Elsa.
 Some other Ailsa relatives: Ailis, Ailse, Ailsha, Allasa, Elsha, Elshe.

Ailsa

Amias or Amyas is a <a href="https://nameberry.com/list/317/unique-baby-names">unique name</a> with an attractive sound and feel and a lovely meaning. Though it might sound like a Biblical name, it is not, but is a surname that may be related to Amadeus or even be a male version of Amy--which would make it one of the few boys' names to be derived from a girls'.
 The Amyas version became known via the hero of the mega-popular 1855 Charles Kingsley novel, Westward Ho!, Captain Sir Amyas Leigh.

Amias

This lovely name from Spenser's The Faerie Queene is borne by a character who represents married love. A related unusual-yet-usable choice: Amabel.

Amoret

Variously spelled Annalise and Annaliese as well as several other forms, this is not a modern smoosh but a traditional German combo-name with a definite Heidi-esque feel. 
 
 Anna of course is familiar and Liese or Lise is a short form of Elizabeth, ala Lisa, But though it may be seen as old style in Germany, it's a recent success in this country: Annalise jumped onto the popularity list for the first time in 1997.
 
Americans prefer the simpler spelling: There are about ten baby girls named Annalise in the US for every Annaliese. Another 100 baby girls were named Analise and Analiese is also found.
 
TV fans know Annalise as the first name of the lead character in ABC's "How To Get Away With Murder," played by Viola Davis, who won an Emmy for the role.

Annalise

This unjustly neglected floral name has a BBC accent and a Greek mythological heritage: Anthea is an epithet of Hera, the Greek queen of the gods, and her name has been used as poetic symbol of spring. 
 Anthea Disney is a high-powered business executive and distant relative of Walt.
 So if you want to go even beyond Azalea and Anemone, you might consider Anthea.

Anthea

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

A softly poetic surname name, associated with poet W.H., Auden is enjoying quiet but marked fashion status. It was chosen for his daughter by Noah Wyle and is definitely one to watch.

Auden

Auriella

Azure is a colorful gender-neutral choice, currently used equally for baby girls and boys in the US. It refers to a specific shade of blue seen in a cloudless sky. Elon Musk recently revealed Azure to be the name of his daughter with Shivon Zilis, twin sister to Strider. While X and Y didn't stand a chance at greater popularity, parents may be inspired to use the name Azure following this celebrity endorsement.
 
In the Middle Ages, azure was another name for lapis lazuli, the gemstone used to make the brilliant pigment seen in much medieval art.

Azure

Calla is a lily name that is much more distinctive and delicate than Lily. Rarely heard today, it did appear in the popularity lists in the last decades of the nineteenth century.
 Calla is the eponymous heroine of the Rebecca Wells novel The Crowning Glory of Calla Lily Ponder, and there's an English rock band called Her Name is Calla.
 Actress Mare Winningham named her daughter Calla way back in 1987.
Sound-alike Cala is an Arabic name meaning fortress.

Calla

Ceire

Both offbeat and upbeat, this evocative traditional Irish name that runs through Celtic mythology is known here via award-winning novelist Cormac McCarthy (born Charles). The author's adopted name is related to Cormac Mac Airt, one of the great legendary high kings of Ireland.
 In two of the Harry Potter movies, Cormac McLaggen is a Gryffindor student.
 And for all you popularity-phobes, Cormac has never yet made it onto the American Top 1000 list.

Cormac

An intriguing mythological name whose one challenge might be pronunciation questions.
 In Greek myth, Danae, a goddess of music and poetry, was the mother of Perseus by Zeus, who appeared to her in the form of a shower of gold. A novel name worth considering.

Danae

A relatively common surname, Dixon would be an inventive way to honor an ancestral Richard or Dick, the X form a lot livelier than the Dickson spelling, just as Dix is a more modern short form than Dick; it would be right at home alongside Dax and Jax.
 But you don't need us to point out the considerable downside of this name. Besides being a sexual slang term, dick is also the most common epithet describing someone who's a jerk or a meanie (trying to avoid other unsavory words here). And Dix sounds exactly like dicks, which makes it not the least bit easier a name to carry these days than Dick.

Dixon

One of the first of the appealing Irish surnames to take off in this country, this <a href="https://nameberry.com/boys-names">boys’ name</a> has long outgrown its "Mellow Yellow" association, which came via the single from a sixties singer-songwriter named Donovan. 
 Donovan was Scottish-born Donovan Leitch, whose name was probably inspired by his father Donald's. He proved to be an adventurous, celestial namer himself--three of his children are Astrella Celeste, Oriole Nebula and Ione Skye.
 Another potential namesake is retired pro bowl quarterback Donovan McNabb.
 Donovan was in the USA Top 1000 as early as 1900.
 Related options are surname Donegan and place name Donegal.

Donovan

One of the new bird names, like Lark and Wren, this one's associated with the billing and cooing sounds of love. Soft and gentle, Dove also has the admirable association with peace.
 Dove was actually an early bird, used as a first name in the seventeenth century and in the U.S. Top 1000 through the 1890's.
 One admirable surname association is with Rita Dove, the Pulitzer Prize winning poet and former United States Poet Laureate.

Dove

A modern Welsh name that will be misunderstood as Irene. 

Eirian

If you're looking for a Welsh name less common than Dylan, Griffin, Evan, or Morgan, you might want to consider this offbeat epithet of the wise wizard Merlin. 

Root name Ambrose is an ancient saints' name derived from the Greek ambrosia, the food and drink of the gods that conferred immortality.

Emrys

Evander is a name that could build on the popularity of shorter form Evan, and could work and play well with schoolmates like Zander and Xander.
 Evander was prominent in Greek and Roman mythology: in classical lore Evander was a wise Arcadian hero who founded the city in Italy that preceded Rome, appearing in Virgil's Aeneid.
 Evander also derives from a Norse name meaning bow warrior.
 In modern times, the name has been associated with boxing champ Evander Holyfield.
 Evander could make a more distinctive aternative to Alexander.

Evander

While Faust, who sold his soul to the devil, was anything but fortunate, this Latinate variation is more commonly heard and accepted.

Fausto

More unusual than Fiona and more user-friendly than Fionnuala, the engaging Scottish Fenella, has been scarcely heard in this country.
 Fenella first became known outside of Ireland when Sir Walter Scott used it for the character Finella Christian in his novel Peveril of the Peak.
 Finola is another underused Anglicization of Fionnuala.

Fenella

Finola, the readily accessible version of some of the more problematic Gaelic versions of the name, would make a welcome addition to the stockpot of Irish girls' names. 

Finola

An ancient Roman clan name, Flavia is one choice that's unusual but historic. Now a Top 60 name in Italy, Flavia has been a rarity in the US, but with the upswing in F names for girls, this could change. Seen more in literature than real life, Flavia was used as far back as an1580 romance, then in a William Dean Howells novel and as a Princess in The Prisoner of Zenda. Although the original pronunciation is FLAH-via, Flavie (as in flavor) could make a cute nickname.

Flavia

One of the jewel names in use a hundred years ago, due for revival along with sisters Ruby and Pearl. 

Garnet

Georgia is so rich, lush and luscious, it's almost irresistible. Georgia's now a rising star among the feminizations of George, helped by associations with the southern state (named for British King George II) and painter Georgia O'Keeffe, with the Ray Charles song "Georgia On My Mind" or maybe "Sweet Georgia Brown" playing in the background. 

 Georgia is in fact a double place name, also belonging to an ex-Soviet state famous for the ancient monastery Vardzia and its rich culinary and wine-growing culture.

 Georgia has been chosen for their daughters by Harry Connick, Jr., Hope Davis, Amy Ryan, Zac Brown, Rebecca Gayheart and Eric Dane, and Felicity Huffman and William H. Macy.

Georgia

Hart could be the hero of a romantic novel, but on the other hand, it's short, straightforward, and strong sounding. The most famous bearer of the name was tragic poet Hart (born Harold) Crane, but it also has musical cred via Lorenz Hart, of the classic Rodgers & Hart songwriting duo and a literary tie to playwright Moss Hart.
 Hart would make an interesting middle name choice--with heart.

Hart

Innis is the name of an island (and Gaelic word for island) which became a Scottish surname and clan name before being used as a first. It hasn't been heard much in the U.S., but could attract more attention with the growing popularity of Latin s-ending boys' names such as Atticus.
 Innis is related in sound to Ennis, as in the character name Ennis Del Mar, indelibly played by Heath Ledger in "Brokeback Mountain."

Innes

Innis

This unusual Greek flower and color name has gained considerable recent attention via actress Ione Skye, who is the daughter of sixties folksinger Donovan.
 Ione was one of the fifty sea nymphs — Nereids — in ancient Greek mythology.
 Parents attracted to newer I-names like Isla might want to consider the distinctive Ione. The English pronunciation usually starts with the long I, while in the Latin languages such as Italian it starts with the long E sound.

Ione

Iris has so much going for it. It's a fashionable flower name. It's a mythological name, from the Greek goddess of the rainbow. And it's a classic name, always ranking in the girls' Top 1000 but now at its highest point ever.
 
Iris is directly derived from the Greek word iris, meaning "rainbow." In Greek mythology, rainbow goddess Iris was a messenger for Zeus and Hera who rode the rainbow as a multicolored bridge from heaven to earth. 
 The botanical iris also carries evocative symbols. In ancient times, the Iris was considered a symbol of power and majesty, the three petal segments representing faith, wisdom and valor. This image led to the naming of the colored part of the eye.
In the contemporary world, Iris has amazing international versatility, ranking highly throughout the English-speaking world as well as in a diverse range of countries from Spain to Slovenia, France to Sweden.
 Part of Iris's rise is due to its celebrity power: Jude Law and Sadie Frost, Judd Apatow and Leslie Mann, and Renee O'Connor all chose Iris for their daughters.
 A notable modern bearer was the prolific British novelist Iris Murdoch. Frequently seen on screen, characters called Iris have been played by Jodie Foster, Jane Fonda and Kate Winslet, and Iris Chase is the narrator in the Margaret Atwood novel The Blind Assassin.

Iris

Isephina

Long used in Spanish-speaking countries, this strong but feminine name was jump-started here by the rise of actress Jada Pinkett Smith. The Italian Giada is a popular variation. In the Bible, the name Jada was borne by a man and has a different root and meaning: It's Hebrew and means "he knows".

Jada

This name of three ancient saints, one Wayans brother, and an NFL wide receiver makes an energetic choice.

Keenan

Lachlan is as Scottish as haggis and tartan plaid kilts—a favorite used throughout England, Scotland, Australia, and New Zealand—and just beginning to be noticed in the US: it reached the Top 1000 for the first time in 2013. An ancient name, Lachlan was originally used to describe the Viking invaders of Scotland, those from the land of the lochs.
 Americans and Australians tend to pronounce the first syllable of the name like Lock, but the genuine Scottish pronunciation sounds more like Lack.
 In Ireland, the name was Anglicized as Laughlin; in Scotland the pet forms are Lach, Lachie, or Lockie.
 Lachlan has been a top name in Australia for at least a decade. It has been in the headlines recently via the eldest son of media mogul Rupert Murdoch.
 Somewhat surprisingly, Lachlan has US presidential cred, as the son of tenth president John Tyler, whose other children included Lyon, Letitia, Tazewell, and Pearl.

Lachlan

Laurel takes Laura back to its meaning in nature, resulting in a gentle, botanical option. Even more directly than Laura, Laurel relates back to the laurel wreath signifying success and peace in ancient Greece and Rome.
 Sweet Laurel has been the unlikely name of two DC Comics superheroes—Laurel Kent and Laurel Gand, aka Andromeda.
 Laurel received its highest ranking in 1956, when it reached Number 241. It may be due for a resurgence, thanks to the trend for <a href="https://nameberry.com/search/girls-names/l">girls' names starting with L</a>. Beware though, that it has the likelihood of being mistaken for Laura and Lauren.

Laurel

Leander is an almost unknown name with great potential as a possible alternative to the overused Alexander. In Greek legend, Leander was the powerful figure who swam across the Hellespont every night to visit his beloved Hero, a priestess of Venus.
 Leander is currently a Top 40 name in Norway; Leandro is the attractive Spanish form, and Leandre is popular in France--it appears in three Moliere plays.
 Leander Sydnor was the name of one of the younger police detectives on The Wire.

Leander

Levon, an unusual alternative to Levi. has two musical associations: it's the title of an Elton John song, inspired by late, great drummer for The Band, Levon Helm--whose birth name was Mark.  Uma Thurman and Ethan Hawke chose Levon for their son.

Levon

Lindy

This name of several early Irish saints makes a nice Logan/Conan alternative. 

Lonan

Lyra is a name with ancient and celestial roots that's finding new popularity thanks to its starring role in Philip Pullman's His Dark Materials series, seen in the movie The Golden Compass. Simple yet unique, Lyra hits the sweet spot between too popular and too unusual.
 
Lyra is a constellation name taken from the lyre of Orpheus. It contains the star Vega and thus could make a melodic choice for a parent interested in music, astronomy, or mythology. It has more depth and history than Lyric, is more unusual than Lila (which it rhymes with). It debuted in the US Top 1000 in 2015.
 Lyra was chosen for their daughter by Ed Sheeran and Cherry Seaborn, as well as Sophie Dahl and Jamie Cullum. And then there's Lyra Belacqua, the heroine of His Dark Materials and The Golden Compass.

Lyra

An unusual and straightforward name with an attractive Scandinavian accent; a royal name in Norway. 

Marit

Oriana is a dashing medieval name, with a meaning similar to Aurora. At this point, though, Oriana is much more unusual than Aurora and makes a unique choice if you're searching for <a href="https://nameberry.com/list/316/baby-names-that-mean-new-beginnings?all=1">names that mean new beginnings</a> or dawn. Strong and evocative, Oriana also has an admirable literary resume. In medieval tales, she was the beloved of the knight Amadis, she appears in at least three seventeenth century plays, and there is an early Tennyson poem called The Ballad of Oriana. Oriana was also sometimes used to refer to Queen Elizabeth I. Oriana Fallaci was a feminist Italian journalist who interviewed many world leaders in the 1960s, 70s, and 80s.

Oriana

Orion is a rising star, with both mythical and celestial overtones.
 The Greek mythological Orion was the legendary hunter who pursued the seven daughters of Atlas, was slain by the goddess Artemis, and then placed as one of the brightest constellations in the night sky by Zeus.
 Mark Twain had a brother named Orion, and Chris "Big" Noth picked the name for his son. It is also a Harry Potter name.
 Orion's Gaelic connection to O'Ryan/Ryan makes it familiar as well as unusual.

Orion

Orson has had in the past a rotund teddy-bear image, a la Orson Welles, who early on dropped his common given name of George in favor of his more distinctive middle one, and who seemed to own it during his lifetime. No longer a single-person signature, it's now an interesting possibility for any parent seeking an unusual yet solid name. It's started to appear to the celeb set--both Paz Vega and Lauren Ambrose have little Orsons.
 The comic actor Orson Bean was born Dallas; there was a Desperate Housewives character called Orson Hodge.
 There's also a fifteenth century story about two brothers named Valentine and Orson, in which the latter was carried off by a bear and raised as one of its cubs.

Orson

Many parents these days are responding to <a href="https://nameberry.com/list/411/baby-names-that-mean-peace">names meaning peace</a>, and this is one of the more unusual ones (more often heard as a surname). Pronounced PACH-ee-a, it relates to such other peaceful names as PAZ, PAX, and PAXICO

Paccia

Rainer is one of those <a href="https://nameberry.com">baby names</a> that is still under-the-radar but has been quietly gaining traction: The number of boys who've received the name has doubled in the past decade, to just under 50. Part nature name and part traditional <a href="https://nameberry.com/baby-names/494/german-names-for-boys">German name for boys</a>, Rainer can claim a place among the two-syllable r-ending baby names so fashionable for boys today.

Rainer

Simone, the elegant French feminization of Simon, strikes that all-important balance between unusual and familiar, and it's oozing with Gallic sophistication. Dwayne "The Rock" Johnson has a daughter named Simone; Chris Rock used it in the middle place for his daughter, as did Kevin Kline and Phoebe Cates
 Two French philosophers are notable bearers of the name: feminist icon Simone de Beauvoir, author of the influential The Second Sex, and Simone Weil. The name might get a bit of a bounce via the two young Simones who shone in the 2016 Rio Olympics--Simone Bile, who set a US record high of four medals in a single Olympics, and Simone Manuel, who became the first African-American female swimmer to bring home a gold.
 The actress who played the lead in the iconic French horror movie Cat People is Simone Simon.

Simone

Although pinochle-playing partner Sam came out of retirement, we don't see it happening to Sol. Near soundalike Saul has more of a shot.
Sol was also a Roman god/personification of the sun, and an epithet of sun-god Apollo.

Solstice graduated from word to official first name when author Lionel Shriver used it for a character in her novel Big Brother. But of course, there were people named Solstice before: 16 baby girls were given the name in the US in 2021 (and it is occasionally used for boys too).

The word solstice is derived from the Old French and Latin term meaning "point at which the sun seems to stand still." There are pagan celebrations around the time of the winter and summer solstices, June 21 and December 21, the longest and shortest days of the year, which makes Solstice one of the best <a href="https://nameberry.com/list/577/names-for-december-babies">names for babies born in December</a> or June.

Solstice

A strong, eminently usable which is currently highly fashionable in its native Scotland, but little known elsewhere. With its cool two-syllable, n-ending shape and attractive nature meaning, Struan is a fresh Scottish name that feels ripe for import.

Struan

Stella-Maris

With its solid Thomas Hardy background, Tess has a lot more substance, strength, and style than most single-syllable names, with an efficient yet relaxed image. 
 The iconic literary Tess is the beautiful heroine of Thomas Hardy's Tess of the D'Urbervilles, the moral center of the novel. Other Tesses have been portrayed on screen by Katharine Hepburn, Julia Roberts, Shirley Maclaine, Melanie Griffiths, Kate Hudson, Jamie Lee Curtis, Cher, Della Reese and Malin Akerman. Novelist and fashion journalist Plum Sykes named her daughter Tess.
 Writer Tess Gerritsen was born Terry, but decided to feminize her name when she began writing romance novels.
 If you'd like to expand the name, you can consider Tessa--or even Tessie

Tess

Thalia was one of the Three Graces in Greek mythology, and also the Muse of comedy and pastoral poetry, making this a Hellenic choice worthy of consideration. 
 In the Rick Riordan series Percy Jackson and the Olympians, Thalia Grace is the demigod daughter of Zeus. Thalia was also a character on Everwood.
 The single-named Mexican singer Thalia was born Ariadne Thalia Sodi Miranda.
 Thalia had a one-off appearance on the list in 1932 and then reentered the US Top 1000 in 1992, reaching its height of Number 363 in 1993.

Thalia

Vera was the height of fashion in 1910, then was for a long time difficult to picture embroidered on a baby blanket. Now, though, it has come back into style along with other old-fashioned simple names such as Ada and Iris. 
 Vera was barely known in the English-speaking world until it appeared in the 1860 novel by Ouida, Moths, and Vera Rostov is a character in War and Peace, published nine years later.
 Vern Yip has a young daughter called Vera, and Vera Wang and Vera Famiga have modernized it. Vera Lynn was an iconic British World War II singer, Vera Miles was a Hitchcock star best known for her role as Lila Crane in Psycho and Vera-Ellen (born without the hyphen) was a dancing partner of Fred Astaire and Gene Kelly.

Vera

Like Vita and Viva, one of several similar life-affirming names, this one was chosen by Matthew McConaughey and his Portuguese-born wife Camila.  

Vida may also be a diminutive of Davida. Australian suffragette and human rights campainer Vida Goldstein is an notable bearer of this name.

Vida

Viva la baby with this life-affirming name, one of the appealing group of <a href="https://nameberry.com/list/607/girl-names-that-mean-life">girl names that mean life</a>.! Singer Rufus Wainwright chose it for his baby daughter, perhaps in celebration of a new life entering the world the year after he lost his mother Kate McGarrigle. The baby's middle name is Katherine. 
 Viva (born Janet Susan) was one of Andy Warhol's single-named superstars.
 Other related life-giving names on the rise: cousins Vida and Vita, and Vivian, Aviva, and even Zoe.

Viva

The name of a Christian saint and a city in Ohio, Xenia is one of the more accessible and intriguing x names. It is the name of one of the Bond Girls--played by Famke Janssen in the film "GoldenEye." 
 
Sometimes spelled Ksenia to reflect the traditional Greek pronunciation (kseh-NEE-uh), Xenia is also pronounced ZEEN-ee-ah or SHEN-yah.
