Bailey -- a jaunty surname -- was first used for a female TV character in 1978 in the show WKRP in Cincinnaati, then caught on big time. Bailey's still an appealing choice, though, and a celebrity fave. Parents of daughters named Bailey include Scot Baio and Stella McCartney.

Bailey

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.
 
In the earliest sources it is recorded as Viatrix, meaning "voyager". Possibly the spelling was deliberately changed to resemble the Latin word beatus, "blessed"; both meanings are part of Beatrix's rich history.
 
It has been largely associated with Beatrix (born Helen) Potter, creator of Peter Rabbit, and Beatrix has been Queen of The Nethelands since 1980.
 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. 
 Both Bea and Trixie are adorable nicknames,and Beatriz is the Spanish form.

Beatrix

One of those casual down-home names last popular in the 1960s. 

Becky

Belinda, cousin of Linda and Melinda, enjoyed a brief return to the Top 1000 from 2005 through 2013, only to fall off again in 2014. A name that some may consider a modern spin on the midcentury popularity queen Linda is in fact a classic with deep and fascinating roots. In Babylonian mythology Belinda was the goddess of heaven and earth, and the name later was used for the heroine of Alexander Pope's satirical poem The Rape of the Lock.
 One of Belinda's meanings is 'beautiful snake' (coined at a time when snakes were a sacred symbol of wisdom and immortality) and it still does seem to have a certain lingering serpentine charm.
 Belinda entered the US popularity lists in 1940, and went on to reach Number 142 in 1961. Both Maria Edgeworth and Anne Rice wrote eponymous novels called Belinda.
 Belinda Carlisle was the lead vocalist in "The Go-Go's."

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

Bell

Everything ella, from Ella to Bella to Arabella, is red hot right now. Bella is one of the most, well, beautiful <a href="https://nameberry.com/search/girls-names/b">girl names starting with B</a>. It carried a hint of a nice Old World grandmotherly veneer, until it became attached to Twilight's Bella Swan. 
Bella derived as a diminutive of Isabella and other names with the suffix -bella, such as Anabella and Arabella, but has a meaning all its own: beautiful.That's because Bella is related to the word for "beautiful" in languages including Spanish, Italian, Latin, Portuguese, and Greek. Belle means "beautiful" in French.
 
If you're thinking of naming your daughter Bella, be aware that there are a lot of little girls whose proper names are Isabella, Arabella etc. who are called Bella, so you may hear the name more frequently than you'd guess judging by popularity statistics.
 In pre-Twilight literature, Bella Wilfer is the central character in Charles Dickens's Our Mutual Friend.
 Mark Ruffalo, Billy Bob Thornton, David Boreanaz and Eddie Murphy are all dads to Bellas. A strong feminist namesake is Bella Abzug. One current Bella is child star turned pop star Bella Thorne, born Annabella.
 Bella was in use as far back as the thirteenth century, then disappeared until the eighteenth when it became fashionable. 
 Today, Bella is among the <a href="https://nameberry.com/popular-names/dogs">most popular dog names</a>.

Bella

Belle has nothing but positive associations, from "belle of the ball" to "Southern belle" to the heroine of Disney's Beauty and the Beast. As if this weren't enough good things, Belle is also one of the most familiar and usable <a href="https://nameberry.com/list/4/baby-names-that-mean-beautiful">names that mean beautiful</a>.
Though it has been overshadowed by the Twilight-influenced Bella and longer forms like Isabella and Annabella, Belle has its own Southern charm and would make a pretty choice as a first or middle name.
 Belle was a Top 100 name in the 1880s, but left the list in 1934. It returned to the US Top 1000 for the first time in 80 years in 2016, only to drop off again in 2021. Its most famous bearer was the legendary Western outlaw, Belle Starr (born Myra); Belle Watling is a character in Gone With the Wind.

After a century of association with horses and cows, this name just could be ready for revival by a fearless baby namer -- after all, it did happen to Jessie and Becky. 
 Bessie has been in use since the seventeenth century and is found as characters in Jane Eyre and in Sean O'Casey's play The Plough and the Stars. More recently, she was an animated automotive character in the movie Cars.
 On the popularity lists until 1975, Bessie was a Top 25 name from 1880 to 1906, reaching Number 9 in 1889. Notable namesakes include the great blues singer Bessie Smith, and Bessie Coleman, the first African-American female aviator.
And if you want to go more refined, you could simplify to Bess.

Bessie

The sweetest and most sensitive of the pet names for Elizabeth, now also one of the most dated. 

Beth

Bethany is a lyrical name that still strikes many parents as a fresher, more substantial substitute for the overused Brittany/Brittney or the more antiquated Beth. 
 In the New Testament, Bethany is the name of a village just outside Jerusalem where Jesus stayed during Holy Week. Mary of Bethany was the sister of Martha and Lazarus.
 A spelling variation was introduced by Real Housewife of New York Bethenny Frankel.

In the USA, Blair is gaining momentum, rising quickly for the last 10 years and likely to continue to climb. In England and Wales, where Blair has political connotations – calling to mind former prime minister Tony Blair – it is much less common, although it is in use for boys in its native Scotland.

 Blair has a chic and tailored feel in line with other trending gender-neutral one-syllable girl names like Sloane, Quinn, Sage, and Reese. A notable pop culture namesake in recent years is Leighton Meester's upper-crusty character in Gossip Girls.

 Blair was first popularized as a girl's name in the 80s, cracking the Top 500 for a few years before falling off again. Blair re-entered the charts in 2011 and has been rising since. Blair has a longer history as a boy's name, with consistent use as early as the 1800s, and the name stayed on the charts until the mid 90s.

Blair

Like Benita, had some popularity in the fifties. 

Bonita

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

Eastern European girl name related to the Slavic word Bóg, meaning "God."

Bozena

First the heroine of Sir Walter Scott's 1822 novel The Pirate, then a glamorous 1940s debutante, then the troubled twin on Beverly Hills 90210, and now fading in favor of more modern Brenna, Briana, and Bryn. Much more likely to be worn by a mother or grandmother these days. The song "Brenda's Got a Baby" was late rap megastar Tupac's debut single.

Brenda

Bridget is the Anglicized form of Brigid, an Irish-Gaelic name that was derived from the word brígh, which means "strength." 
Bridget is the name of the most famous female saint of Ireland, who became the patroness of her country, as well as patron saint of scholars, poets and healers. Because of her sanctity, the name did not come into common use in Ireland until the seventeenth century, after which it became wildly popular. Bridget eventually came to be used as a pejorative name for an Irishwoman; Irish maids in the early 20th century US were derogatorily called "the Bridgets."
 
One of the earliest <a href="https://nameberry.com/baby-names/509/irish-names-for-girls">Irish names for girls</a> to immigrate to the USA, Bridget, the most familiar form of the name of the Celtic goddess of wisdom, is still used by traditionalists but also carries some modern spark and a great meaning. Bridget is one of the exclusive group of <a href="https://nameberry.com/list/96/girl-names-that-mean-brave-or-powerful">girl names that mean strong, brave, or powerful</a>.
 
According to Irish myth, there were three sister goddesses named Brigid: the goddess of poetry, the goddess of healing, and the goddess of agriculture.
Most prominent Bridgets today are actresses Fonda and Moynahan, op artist Bridget Riley, and the fictional hapless Bridget Jones—she and her diary the protagonist of four books, three movies, and even a musical.
 
Irish variants include Brighid, Brigid (as in the devious character in The Maltese Falcon), Bridie, Biddy, Brid and Bedelia.

Brinley was a surprise entrant to the <a href="https://nameberry.com/girls-names">girls’ names</a> list in 2009, coming in at Number 778; it has since risen to Number 337. We've also seen it spelled Brinlee, Brinlea and Brinleigh.

Bristol Palin, the daughter of former Alaska governor and Vice Presidential candidate Sarah Palin, grabbed her own share of headlines by having a baby out of wedlock and then appearing on Dancing With The Stars. She single-handedly propelled her distinctive name, inspired by a city in England, into the Top 1000 and up the charts. Bristol's ascent ended a few years back.

Brita

Brooke has long projected an aura of sleek sophistication, and can also be seen as a stylish water name.
 It was Brooke Shields (born Christa) who took it from quietly fashionable to ultra trendy when she was just a young girl; socialite Brooke (born Roberta Brooke) Astor gave it social status. 
 Brookes have appeared on soaps like The Bold and the Beautiful" and All My Children, and on Melrose Place and One Tree Hill.
Chynna Phillips and Billy Baldwin have a daughter named Brooke.

Brooke

Slightly awkward girl's version of a straightforward male name.

Brycin

Combining popular names Brynn and Ryleigh produced a new name that has ranked in the Top 1000 since 2010, never surpassing the top mark set at Number 841 in 2013. Trendiness personified.
 Alternate spelling Brylee has fared a little better, peaking at Number 408 in 2012.

Bryleigh

Bryony is an unusually strong plant name --the bryony is a wild climbing vine with green flowers --that caught on in the U.K. before sprouting here. The name of the young character in the Ian McEwan novel Atonement is spelled Briony, which is the variation and Bryony the original.
 Bryony sounds a lot fresher than the now dated Brittany. Pronunciation is like Brian with an ee at the end, though the name bears no relationship to the male Brian or Bryan.

Bryony

Bunny may be adorable, but is it really enough of a name for your daughter?  Plus if Buffy is fluffy, what would that make Bunny?  Still, Bunny as a baby name is in the spotlight since Bryan Adams named his little girl Mirabella Bunny.
