This pretty palindrome name is rarely heard in the US, but could make an interesting namesake for an aunt or grandma Ann. It's also a German diminutive form of Anna.

Anina

Once a Top 100 name, this Spanish diminutive of Ana still retains some of her Latin flair. A notable namesake is noted attorney Anita Hill, another is the great jazz singer Anita O'Day. Plus there's Disney cred via the lead human character in 101 Dalmatians.

Anita

An ancient Roman name that has never made it into the modern world.

Annia

Simple and yet distinctive, Ara is a mythological name of a famously handsome king. Although it originated as a boys' name, in the contemporary US, it's now much more commonly used for girls.
 Ara was one of the many vowel-heavy two-syllable names popular at the end of the nineteenth century and into the twentieth--it went as high as Number 481 in 1884. It's also used as a nickname for Arabella.

In 2010, baby boys named Ari outnumbered baby girls 4 to 1; today, there are nearly equal numbers of boys and girls named Ari. And that's only counting the babies who receive Ari as a full name. Ari can also be short for not only Ariel but Aria, Arya, Ariana, and any other name starting with Ari. Ari entered the US Top 1000 for girls in 2016.

Ayn is a nonconformist name associated with controversial Russian-born writer and philosopher Ayn Rand, (born Alisa) author of The Fountainhead, who adopted it when she moved to the US in 1926.

Gently appealing, a floral choice in Japanese.

Bara

The kind of cutesy female spin not popular since Barry was big for boys, several decades ago.  Consider Bara instead.

Barrie

One of the most usable of the pleasant, newly adopted nature/water names (like Lake and Ocean), especially in middle position. 
 There was a character named Bay Kennish on the show Switched at Birth; conservative political commentator Bay Buchanan was born Angela Marie.
 Other associations with bay are the bay laurel tree, prized since ancient times for its medicinal and culinary (bay leaves!) properties, and the reddish-brown color usually applied to horses.

Bea is a former old lady name that's cute again as a short form -- and is now beginning to stand on its own. Bee is a variation that, like Bea, can work as a diminutive for any name that starts with the letter B, or in the middle. Bea actually stood alone on the popularity lists for four years at the beginning of the twentieth century--and it could happen again.
 Golden Girl Bea Arthur was born a Bernice.

Up-and-coming actress Beanie Feldstein is attracting attention toward her unusual — but rather cute — nickname. She was born Elizabeth Greer Feldstein but nicknamed "Elizabeanie" by her childhood nanny. It was later simplified to Beanie by her older brothers.

Beanie

These days, it's more likely you'd call your daughter the popular Belle or Bella.

Bell

Bennie

Dated British favorite that never caught on in this country, where Jade remains the green gem of choice. 
Interesting namesakes: British writer Beryl Bainbridge and British aviatrix Beryl Markham.

Beryl

Combine the popularity of Betty White and Mad Men's glamorous Betty Draper Francis, with the residual sweetness of Ugly Betty's Betty Suarez, and the result is an impending return of the name. It's got presidential cred via Betty Ford and feminist history through Betty Friedan.
 
Betty's image is still very World War II, when Betty Grable was a hot pin-up girl and Betty was the all-American girls' name blanketing the country, second only to Mary from 1928 to 1934. 
So yes, Betty has been out for so long now that we are starting to imagine a new generation of adorable baby Bettys. We may be on the precipice of a Betty wave, thanks to Blake Lively and Ryan Reynolds, who recently chose it for their third daughter.
 
Bette Davis pronounced her name 'Betty,' while Bette Midler is 'Bet.'

Betty

Like Minnie and Winnie, eccentric enough to appeal to the iconoclastic parent. 

Binnie

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.
 In an earlier heyday of nickname names--the 1880's--Birdie was a Top 200 name.

Birdie

The archetypal diminutive, in every sense of the word. Bitsy enjoyed some use as a nickname in the era when children were named after family members and then called by a cute pet name: Chip, Skip, Babe, Bitsy. As a full name, it has made the US list only three times: in 1943, 1958 and 1962.

Bitsy

Blue suddenly came into the spotlight, as the unusual color name chosen by Beyonce and Jay-Z for their baby girl Blue Ivy. Blue is also a starbaby middle name du jour, used for both sexes in different spellings and forms, from John Travolta and Kelly Preston's Ella Bleu to Alicia Silverstone's Bear Blu. Dave 'The Edge' Evans named his daughter Blue Angel back in 1989.
 Blue is the heroine of the trendy Marisha Pessl novel Special Topics in Calamity Physics.

Blue

Bonnie is an adorable nickname name, heading back up the popularity list after a 50-year nap. A Top 100 girls' name throughout the rest of the English-speaking world, Americans are later to jump on the Bonnie bandwagon but now it's trending here too.
 
Bonnie is a word the Scots really do use for pretty, thus the root of this name, from the French bonne. Along with Betty and Bea, Bonnie, is one of the vintage <a href="https://nameberry.com/search/girls-names/b">girls' names starting with B</a>that are back in.
 Gone With the Wind gave Bonnie a big push when Scarlett and Rhett used it for their daughter. Her full name was Eugenie Victoria, but the pet name came from the fact that she had "eyes as blue as the bonnie blue flag." 
 Bonnie's last moment in the limelight came in the late sixties with the film Bonnie and Clyde, about outlaw Bonnie Parker. Now after a long decline, it's finally showing new signs of life, perhaps thanks to the Bonnies in The Vampire Diaries and The Hunger Games, as well as a new miniseries about the 1930s-era bandits.

Bonnie

Fairy-tale memories of Sleeping Beauty inspire some parents—such as Rachel Bilson and Hayden Christensen—to call their daughters Briar Rose. But Briar plus a different middle name might work even better. It's one of the newly popular nature-word names, charting in the US for the first time in 2015 for both genders.
 While there are about four girls named Briar to every three boys, the name is on the rise for both genders. It could make for an interesting choice to honor a Brian.

Briar

Bryn is an up-and-coming gentle, yet substantial, Welsh name that would also be effective in the middle spot. In Wales it's a traditional boys' name, but it's far more popular for girls now in the US.
 Bryn entered the U.S. girls' popularity list in 1999 but is outranked by the Brynn spelling. Reality star Bethenny Frankel named her daughter Bryn in 2010.
 Trivia tidbit: Bryn Mawr college was the first institute of higher learning to offer graduate degrees to women.

Bryn

Beru

An English diminutive of Isabel or Elizabeth that works best with a longer form on the birth certificate.

Ibby

Many vowel names stylish a century ago are coming back, and Ida seems like a possible, logical successor to Ada and Ava.
 A century ago, Ida was considered "sweet as apple cider," and was Number 10 on the hit parade of names. Its popularity then was inspired by a Tennyson poem, of which the Gilbert and Sullivan operetta Princess Ida, was a "respectful operatic perversion."
 Ida hasn't been in the Top 1000 since the 1980s, but we do see it as slated to rise again. It is hugely popular right now in Scandinavia and German-speaking parts — Top 100 in Denmark, Norway, Sweden, Germany, and Austria — where it's pronounced EE-da.
 Ida appears in Greek and Hindu mythology; Mount Ida, on Crete, is considered the birthplace of the god Zeus. Journalist Ida B. Wells was its most well-known bearer in the US.

This suffix is used as an independent name, but doesn't your little girl deserve more? 

Irina is a Russian ballet-inflected classic, one of the Three Sisters in the Chekhov play.  While some Americans will pronounce this like Irene with three syllables, the pronunciation used throughout Europe, where it's widely used, starts with a short i as in it or if and a strong emphasis on the second syllable.

Irina

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

Juno is an ancient name that feels as fresh as if it had been minted &mdash; well, not yesterday, but in 2007. Since the release of the popular indie film Juno, this lively but strong o-ending Roman goddess name has become more and more prominent as a potential baby name &mdash; Coldplay's Will Champion chose Juno for one of his twins (whose brother is the kingly Rex).
 
Juno was the sister and wife (hmmm) of Jupiter, and the mother of Mars and Vulcan. The patron goddess of Rome and protector of women and marriage, Juno's name is heard in Virgil's Aeneid, Shakespeare's The Tempest, and Sean O'Casey's 1924 play Juno and the Paycock. The deity's name is of uncertain origin, but likely derives from the root -iuwen, meaning young. With Jupiter and Minerva, she made the Capitoline triad, whose worship was at the very center of Roman religion.

Juno

Mabel is a saucy Victorian favorite rising in popularity in the US over the past decade, after a 50-year nap If you love offbeat old-fashioned names like Violet or Josephine, only sassier, Mabel is one for you to consider.
 In the 1880s and 1890s, Mabel was a Top 20 name. Some of Mabel's vintage cultural references include Charlie Chaplin's favorite leading lady Mabel Normand, jazz singer Mabel Mercer, the lead character in Gilbert & Sullivan's Pirates of Penzance
 There is a Princess Mabel in the Netherlands today, born a commoner and the widow of Prince Friso. Several celebrities have named their daughters Mabel, including Chad Lowe, Nenah Cherry, Bruce Willis and Dermot Mulroney., and the baby on the sitcom Mad About You (in which Mabel was an acronym for Mothers Always Bring Extra Love--a nice thought).

Mabel

A multi-cultural name that's in the Norwegian Top 50 and well-used throughout the Scandinavian cultures. Malin has the advantage of being at once simple and unusual.

Malin

A hum of a name occasionally heard. Madame Mim was a villain in Disney's "The Sword in the Stone." 

Sweet, nicknamey name belonging to the tragic heroines of both La Bohème and Rent. Mimi might feel too slight for many parents to use on the birth certificate, but as a short form, it's one of the cutest of the <a href="https://nameberry.com/list/508/cute-baby-names-for-girls">cute baby names</a>.

Mimi

Bobbsey Twins-era nickname name that could find new life via Nan, heroine of The Nanny Diaries. Nan was also the nickname of Annabel St George, the protagonist of Edith Wharton's novel "The Buccaneers".

To most English speakers, Nana is the dog in Peter Pan, the daughter played by Emma Stone in Crazy Stupid Love, and another name for Grandma.

Nana

Nann

Nanou

Soft, simple, and far more unusual than Tara or Farrah.  As a Japanese place name, it's been used occasionally as a surname and is beginning to be used as a first.  Nara is also the name of a Hindu (male) God and the name means "man" in Hindi.

Nara

Nena

Because of its meaning, this is a symbolic name given to girls born on Hanukkah, the Festival of Lights. 

Nera

 Current bearers include actresses Long and Vardalos (born Antonia), and popular television show Dance Moms star Nia Frazier.

Better hold off and hope for a daughter so you can name her Anais. 

Nina is as multiethnic as you can get: Nina is a common nickname name in Spain and Russia, a Babylonian goddess of the oceans, and an Incan goddess of fire. Here and now, it's a stylish possibility that's been underused. "Weird Al" Yankovic chose this decidedly nonweird name for his daughter.
 Nina has been a permanent resident on the Social Security list, mainly in the low hundreds. 
 In literature, Nina Zarechnaia is one of the principle characters in Chekhov's drama The Seagull, as well as appearing in Trollope's Phineas Finn and Evelyn Waugh's Vile Bodies.
 More recent real-life bearers have included jazz singer Nina Simone (born Eunice) and Nina Garcia of Project Runway fame.
 Natalie Portman was awarded an Oscar for her role as ballerina Nina Sayers in the 2010 Black Swan.

Nina

Ninna

Sweet and charming French nickname for Anne, à la Manon for Marie. 

Ninon

One of those slender names, like Lena or Etta, that's used in several cultures and carries a range of meanings. But by being so many things, it doesn't feel decidedly like anything.

Nita

Nora is a lovely, refined name that conjures up images of Belle Epoch ladies in fur-trimmed coats skating in Central Park. Long seen as a quintessentially Irish name though its roots are not in Ireland, Nora is a quietly stylish favorite that's tiptoed to the top of the popularity ladder.
 
Nora has two separate origin stories, as a derivative of both Honora and Eleanor. The Irish and Anglo-Norman version derives from Honora, based on the Latin word honor. The Hungarians spawned Nora as a short form of Eleonora, a variation of Eleanor.
 One of Nora's most prominent contemporary namesakes is the late witty writer Nora Ephron. Other notable Noras are the independent Ibsen heroine of A Doll's House, and the female half of the witty Nick and Nora Charles duo, adding up to a most desirable choice. 
 It can also be spelled Norah, as in Norah Jones.

Nora

Norie

Short and feminine, Ria has a rhythmic flow. 

A very popular girls' name in Japan whose sound is consistent with its meaning.  Another possibility is Ren.

A pan-European short form often used as a name in its own right, Rina is sister to names like Mina and Lena, popular at the end of the 19th century and showing their pretty if slight faces again.  In the Netherlands, Rina itself is sometimes shortened to Rineke, as Tina may become Tineke.

Rina

Rosy-cheeked and cheery, Rosie (also spelled Rosy) has been standing on her own for many decades, back to the days of 1943 musical Sweet Rosie O'Grady.

 A hobbit character in Lord of the Rings, Rosie's current representatives include Rosie (born Roseann) O'Donnell, Rosie Perez (born Rosa), and British-born pregnancy guru Rosie Pope. The Rosie Project is a 2013 bestselling novel by Graeme Simsion.

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

An ancient tree that figures in literature from Shakespeare to Harry Potter and is believed to possess magical powers, Willow is a lovely name, as graceful as its inspiration.
 Willow's use as a given name derives directly from the willow tree, whose name was derived from the Old English word welig, meaning "willow." Willow trees are associated with grace and elegance, which gave way to the adjective "willowy." Other names with meanings related to willows include Arava, Willoughby, Dozier, Wellesley, Selby, and Salton.
 
This elegant and charming nature name has been chosen for their daughters by Will Smith and Jada Pinkett Smith, Michelle Monaghan and Pink. It's been a fast riser in recent years, climbing along with other Will names Willa, William and Will, having taken off here a year after the character of Willow was introduced on Buffy the Vampire Slayer in 1997.
 
Willow is also popular in other English-speaking countries: Australia and the UK, Canada, Ireland, and Scotland.
 
The name has transcended its one-time hippie aura to move into the realm of reappraised and appreciated <a href="https://nameberry.com/list/329/nature-baby-names">nature names</a>. The willow is believed by the Romani to possess the ability to heal the sick and rejuvenate the aged.
 
Pink was quoted as saying her choice was influenced by a willow tree she grew up near, and that it is the most flexible tree that nothing can break—no wind, no elements, it can bend and withstand anything.

Willow

This pet form of such names as Winifred and Edwina and Gwendolyn has loads of vintage charm, a la Millie and Maisie, with a decidedly winning vibe. And it just got celebrity cred as the baby daughter of Jimmy Fallon.
 Winnie had been used regularly on its own in the U.S. through the early 1950's and has a number of varied namesakes. There's the Pooh, of course, and also Winnie Mandela, former wife of South African President Nelson; Winnie Cooper, the charming girlfriend of the young hero on The Wonder Years--whose given name was Gwendolyn; Winifred "Winnie" Foster, a main character in the childhood classic Tuck Everlasting; and it was also a nickname for Winston Churchill.

Winnie

This name can be used for either girls or boys and is a great international choice.

A feminine multicultural nickname name perfectly able to stand on its own. 

Zanna

Zinnia is an unusual floral choice with a bit more edge and energy than most and beginning to find its way onto namers' wish lists of botanical possibilities. Named after an eighteenth German botanist called Johann Gottfried Zinn, it appears in Roald Dahl's Matilda as the young protagonist's mother.
 In the language of flowers, Zinnias symbolize remembrance.

Nicknames for Brianna Jane

Brianna is a beautiful name, but when you discover that there are four Briannas in your daughter's preschool class, you're tired of the nickname "Bri" and its variations, or you're looking for a nickname that's withstood the test of time, you might not know where to start.
