Acacia is an attractive, rarely used Greek flower name enhanced by its popular beginning-and-ending-with 'a'-construct, and is gradually beginning to catch on as a new member of the stylish <a href="https://nameberry.com/search/girls-names/a">girl names starting with A</a>. 
 The acacia is a shrub of the mimosa family, with clusters of showy white or yellow blossoms, which symbolizes resurrection and immortality--making the name especially appropriate for an Easter-season baby.
 Named by an early Greek botanist, the acacia is known for its fine wood and medicinal properties. It also has biblical ties, since the Ark of the Covenant was made out of Acacia wood.
 As a given name, Acacia has had some popularity in Australia, where the acacia (sometimes known there as the wattle) is a common plant and sometime national symbol.

No longer tied to the hapless Ace Ventura, this jaunty, high-flying nickname name is starting to take flight among celebrity and other parents, with its countless positive references to doing well in tests and poker games, on the tennis court and golf course, and in the air.
 Natalie Appleton, Tom Dumont, Jennie Finch, and Jessica Simpson all have little Aces. The best known grownup with the name is Ace Frehley, born Paul, one-time KISS guitarist.

In Greek mytholgy, Antigone was the noble and courageous daughter of Oedipus, who acts as his guide after he blinds himself. Antigone is also the eponymous heroine of a play by Jean Anouilh.
 Despite her heroism, however, Antigone has not yet made it into the modern world, but with the increasing acceptance of longer, weightier Greek and Roman names, this could change.

Antigone

With mythological names rising, the handsome son of Zeus and god of medicine, music, and poetry among many other things might offer an interesting, if high-pressure, option. 
 
But if Romeo and Venus are now deemed baby-appropriate, why not Apollo? Olympic speed skater Apolo Anton Ohno might inspire some parents. And now that it's been chosen by Gwen Stefani and Gavin Rossdale, it could take off as their first son's name—Kingston—has.
 Other cool associations include NASA's Apollo program, from 1961-72, that succeeded in putting the first humans on the moon when astronauts Neil Armstrong and Buzz Aldrin landed their lunar module and walked on the moon's surface. There's also the historic Apollo Theatre in Harlem, on whose stage the careers of Billie Holiday, Ella Fitzgerald, Artetha Franklin, Stevie Wonder, the Supremes, the Jackson 5, and countless others were launched.

Araminta is an enchanting eighteenth-century invention familiar in Britain and just beginning to be discovered here. It was used in 1693 by William Congreve in his comedy The Old Bachelor, and in 1705 by the versatile Sir John Vanbrugh, architect of Blenheim Palace as well as a playwright, for his comedy The Confederacy.
 In the Enid Bagnold novel National Velvet, Araminta is the name of the central character's mother.

Archer is an Anglo-Saxon surname that feels more modern than most because of its on-target occupational and Hunger Games associations. And it's a nice way to bypass the clunky Archibald to get to the cool nickname Archie.
 But have a look at that amazing popularity chart below: After 1889, Archer took a 130-year nap, resurfacing on the Top 1000 in 2009 and now shooting straight upwards. Five years ago, we named Archer one of our Hottest Names of 2011—and, indeed, it jumped 102 places that year, thanks in part to Archer's similarity to popular Asher and its cross-gender appeal. Moms may like its literary gentility and dads its tough-guy FX cartoon appeal. Or, of course, vice versa.
 Trivia tidbit: Archer is the name of Dr. Doolittle's father.

Archer

This name of the Cretan goddess of fertility is most popular now as the more melodic Ariana, but Ariadne has possibilities of its own. It first entered the US Top 1000 in 2014. The renewed interest in the name falls in line with the revival of other mythological names like Apollo and Athena. The trendy nickname Ari doesn't hurt either.
 In Greek mythology, she was the daughter of Minus who gave Theseus the thread by which he escaped from the labyrinth. After being deserted by him, she married Dionysus, the god of fertility, wine and drama

Ariadne

Words are not always easy to translate into <a href="https://nameberry.com/">baby names</a>, but the implications of being straight and swift lend this one great potential as a name. It also has the popular o-sound ending, which brings it further into the realm of possibility. Rising rock star Aja Volkman pulled a gender switch when she named her daughter Arrow Eve.

Arrow

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

This hyper-rhythmic name has two evocative references. In Greek mythology, she was an island nymph, a daughter of Atlas, who delayed Odysseus from returning home. It is also a genre of West Indian music, originating in Trinidad and Tobago and largely popularized in the States by Harry Belafonte. 
 Calypso was the name of Jacques-Yves Cousteau's research ship--and would make a highly dramatic, musical choice.

Calypso

Chosen by the late Kobe Bryant and his wife Vanessa for their youngest daughter, there is renewed interest in Italian isola name Capri.

Capri

Clio is the name of the ancient Greek mythological muse of history and heroic poetry, one that is rich with modern charm and would make an intriguing choice, especially thanks to its dynamic o-ending. 
 Unlike the sound-alike Cleo, which brings up visions of Cleopatra, Clio is very much a stand-alone name. The only problem? Some might associate it too heavily with the car model, but that will hopefully fade with time.
 In English, the first syllable is emphasized, however, in the original Greek, it is the second O that is more prominent. 
 If you love Clio, you could consider other Greek muse names: Thalia and Calliope.

Clio

Flint is one of the new macho names on the rise today, part old-school tough guy, part rebel. You won't find a tougher, steelier-sounding name; it's part of a genre on the rise along with cousins Slate, Stone and Steel. 
 Flint found itself on the popularity list for a few years in 1959-60, but would prove a distinctive choice today.
 Flint has superhero overtones--there's one in "Spiderman"--aka Sandman--and Captain Flint was a Marvel comic, and Flint is both a legendary pirate and a parrot in Robert Louis Stevenson's Treasure Island. But on the softer side, there's also inventor Flint Lockwood in Cloudy With a Chance of Meatballs.

Jezebel, the wife of King Ahab in the Hebrew Book of Kings, has long had a bad girl reputation. But in the modern secular world, this is somewhat mitigated by the feminist perspective of her as a strong woman, the power behind the throne. Previously avoided as a baby name, Jezebel is now, along with the also previously avoided Delilah and Desiree, coming into use, helped by its relation to other 'bel' name such as Isabel and Bella.
 
The popular feminist celebrity blog Jezebel upped the name's cool factor. Jezebel is the title of one of Bette Davis's best known early films.

Jezebel

Lucette

Lucienne is a soft and ultra-sophisticated French-accented option in the Lucy family, one that could provide a fresh alternative to such fatigued Gallic choices as Danielle and Michelle.
 So if you're looking for a more elegant take on Lucy, this could be it. The original male Lucian is a Latin name while Lucien is the French form and Lucienne is a female spin on that.

Lucienne

When R & B singer Nivea made this highly original choice for her daughter's name back in 2005, she claimed to have thought of it in terms of the color and not the seagoing armed service. As a word with multiple meanings, however, it could easily work as a nod to a naval officer in the family or to someone who enjoys sailing.
 
Ultimately deriving from the Latin word navigia meaning "boats", Navy can refer to a fleet of ships, to the armed forces of the sea, or to the dark shade of blue, named for the traditional color of naval uniforms. As a name, it could fit in with the likes of Indigo, Scarlett, Hazel, or Sailor - and based on its sounds, with Maeve, May, and Ava.
 
Following Nivea's use of the name, it did slowly begin to climb the charts throughout the late 2000s and early 2010s, but, after a boost in 2019 when country singer Jason Aldean gave it to his daughter, it entered the Top 1000. Currently a Top 500 name for girls in the US, it is also in the UK Top 1000 and gaining attention as an option for boys too.

Navy

The association with the infamous Nero, the fiddling Roman emperor, would be unavoidable. But there was also the detective Nero Wolfe, hero of many mystery stories.
 Nero was born Lucius Domitius Ahenobarbus, and Lucius might be a preferable choice if you know anything about ancient Roman history.

Nero

A name that Yanks might see as overly British, but combined with the right surname, it does have a measure of Sherlock Holmesian dash via Nigel Bruce, who played the original Dr. Watson to Basil Rathbone's Sherlock Holmes. 

Nigel

In Greek mythology, Nyx was a powerful goddess and the embodiment of the night, but when spoken, its negative meaning can't be ignored. 

The name of the brave, resourceful hero of Homer's epic saga has almost always been considered too weighty for a child to bear, but at this point, some brave, resourceful parents out there might be willing to take it on.

Odysseus

With its relation to Mount Olympus, home of the Greek gods, and to the Olympic games, this name has an athletic, goddess-like aura, making it the perfect Olivia substitute.
 A well-known art reference is the famous 1865 painting of a reclining nude by Edouard Manet titled Olympia. Contemporary bearers include former Maine Republican Senator Olympia Snowe and actress Olympia Dukakis.

Olympia

Onyx is a fresh and trending gemstone name for boys, currently in the US Top 500, having climbed the charts rapidly since 2018. Now, an increasing number of girls are receiving the name, with a recent count revealing nearly 200 baby girls were called Onyx in 2023. 
 
This sleek, often shiny and black gemstone gets its name from Greek, in which it means "claw, talon, or nail" due to its mythological creation story, in which it formed by Cupid trimming Venus's fingernails. As a stone, it is said to protect against nightmares and improve concentration, while as a name, it feels reminiscent of other unisex options, like Phoenix or Alex, and like other cool gems like Opal and Sapphire. 
 
Nick Cannon and LaNisha Cole chose Onyx Ice for their daughter in 2022, which may boost the name further.

Onyx

Floral, elegant, and bold, Ophelia re-entered the US Top 1000 in 2015 after more than 50 years off the charts. It has risen more than 700 spots since then and shows no signs of slowing down. Now in the US Top 300, could Ophelia one day become the next Olivia or Amelia?
 
It's certainly catching up in the UK, where, as of 2022, it's in the Top 100 and given to nearly 600 baby girls. Less likely to be heard as 'I feel ya', as it is pronounced with four syllables in the UK, Ophelia makes an arty but approachable choice. 
 Derived from the Ancient Greek word "opheleia", which means "help", Ophelia was used first by the poet Sannazaro in his 15th century poem "Arcadia". It was then popularized by Shakespeare's Hamlet in the 1600s and again in the 19th century by John Millais' painting. 
 
Other namesakes include the gutsy Ophelia in Harriet Beecher Stowe's 1852 Uncle Tom's Cabin, which seems to have had some influence on baby namers at the time, and more recently, the song "Ophelia" by The Lumineers.
 Among the actresses who have played modern non-Shakespearean Ophelias are Jamie Lee Curtis in "Trading Places" and Blake Lively in "Savages". The heroine of the film Pan's Labyrinth uses the Spanish spelling, Ofelia, while a popular YA novel, Ophelia After All by Racquel Marie sticks with the Shakespearean one.
 Actress Patricia Neal and author Roald Dahl named one of their now grown daughters Ophelia, and more recently musician Dave Grohl named his baby girl Ophelia Saint.
 
A hugely popular name on Nameberry and now out in the 'real world' too, you may hear this Shakespearean gem more often in the coming years. So, if you love Ophelia but want to beat the trends, you could try Cressida, Olympia, Cordelia, or Cerelia.

Ophelia

Otto is cool again. Long a quintessential Old Man Name, Otto has been promoted to trending darling of adventurous baby namers. 
 Like most <a href="https://nameberry.com/baby-names/160/german-names">German names</a>, Otto fell out of favor during and after the two World Wars – it had been a Top 100 name in the years preceding. Off the Top 1000 from the mid-1970s until 2011, Otto is now headed straight uphill.
 <br/
There were some distinguished Ottos before the imperial image of Prussian Otto von Bismarck colored the name. Otto the Great is generally considered the founder of the Holy Roman Empire and there were several German and Austrian royals with the name. 

 Otto Frank was the father of Anne Frank, the young Jewish girl who wrote her famous diary during her family's years in hiding from the Nazis during World War II. She was killed in Bergen-Belsen concentration camp in 1945 and her father Otto typed and edited the diary himself to prepare it for publication. 

 Otto Hightower is a character in the Game of Thrones universe, played by Rhys Ifans in the HBO prequel House of the Dragon.

 Feminine forms of Otto include Ottoline, Ottilie, Odilia and Odette, all fashionable in the UK along with Otto itself.

Otto

Curiously appealing, in a hoop-skirted, wasp-waisted way, Ottoline has recently entered the realm of modern possibility, especially since Sienna Miller chose it as the middle name of her daughter Marlowe.
 Lady Ottoline Morrell was an influential British aristocrat who was a force in the artistic and literary community of her day, patron of such figures as T. S. Eliot and Aldous Huxley.
 The Franco-German Ottolie is an equally intriguing option.

Ottoline

Petal is the soft and sweet-smelling name of a character in the novel and film, The Shipping News. With the rise of such flower names as Poppy and Posy, we believe Petal — down-to-earth yet romantic — has its own appealingly distinctive style. Celebrity chef Jamie Oliver named his daughter Petal Blossom Rainbow in 2009.

Petal

This name of a tragic figure in Greek mythology, the daughter of King Minos, sister of Ariadne and wife of Theseus, has a mysterious and intriguing appeal, and would make a dramatic choice.

 Phaedra has been a persistent theme in literature, both ancient and modern. There have been plays by Euripedes, Racine, Unamuno, and O'Neill, novels, poetry, operas and film--as recently as the 2011 Immortals starring Freida Pinto.
 One celebrity pulled a gender switch when she named her son Phaedra Bloom Forever.

Phaedra

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

Zion has taken off in recent years, especially after singer Lauryn Hill used it for her son in 1997 and incorporated the name into a hit song. It combines a user-friendly Ryan-Brian sound with the gravitas of religious significance. The Hebrew pronunciation is 'tzeeyon'.
 In the Old Testament, the name Zion frequently refers to the city of Jerusalem as a whole, and came to be symbolic of Jewish national aspirations, and thus was the source of the term Zionism.
 
With its cool, sharp Z sound, Zion was given to nearly 2900 boys — and to 130 girls — in 2023, placing it in the US Top 150. Also on trend in the UK, New Zealand, and The Netherlands, Zion may well continue to rise in coming years, though some may find it a controversial choice.

Zion

There are many variations of this name, with or without the initial T and the final h, with one p or two.  In the Bible she was the wife of Moses.
