Ansel, primarily associated with the great western photographer Ansel Adams, famed for his magnificent photographs of the Yosemite Valley, could make a creative artist-hero choice. For Adams it was a family name – he was named after his uncle, Ansel Easton. And, in turn, Adams was the namesake of young heartthrob Ansel Elgort, son of a photographer.
 Derived from the same root as Anselm, Ansel is a medieval Germanic name that still feels fresh and stylish today.
 Ansel has been far from a <a href="https://nameberry.com/list/317/unique-baby-names">unique baby name</a> – it was on and off the popularity lists in the late nineteenth and early twentieth centuries, reaching as high as Number 540 in 1893.

Bear has suddenly lumbered onto the baby name landscape.  Perhaps inspired by British adventurer Bear Grylls (born Edward Michael), first celebrity chef Jamie Oliver used it as the middle name for his boy Buddy, and more recently Alicia Silverstone called her son Bear Blu., followed by Kate Winslet's Bear Blaize. It's part of a current trend normalizing once aggressive animal names like Wolf and Fox. Bear is now Number 218 on Nameberry and in the Top 900 in England.

A nature name, a word name, and a surname name, Brooks has plenty of cool factor. It gives off cowboy vibes and a sporty feel, while also maintaining a smart, collected image. 
Used occasionally as a given name throughout the 20th century, Brooks gained serious attention during the 2010’s. Following fast on the heels of stylish Kai and classic Jack, Brooks is now in the US Top 100. 
Derived from the English surname Brook, meaning “one who lives near the steam”, Brooks could appeal to anyone who wants an outdoorsy <a href=“https://nameberry.com/list/756/best-nature-names-for-boys”> name connected to nature</a> and to those enjoy the sleek, smart trend of <a href=“https://nameberry.com/list/358/surname-baby-names”>surnames as first names.</a> 
While it might feel very contemporary, Brooks has made its mark on history. Brooks Calbert Robinson played for the Baltimore Orioles from 1955 to 1977 and is considered one of the greatest third basemen ever. Other notable namesakes include: Brooks Atkinson an influential theatre critic; Brooks Betts, the guitarist of rock band “Mayday Parade”;E. B White, the author of Charlotte’s Web, who was born Elwyn Brooks; and Brooks Harris, a physicist. 
With a more masculine slant than Brooke or Brooklyn, Brooks is given to over 4000 boys each year. It could be set to rise higher in the charts over the coming years, so if you enjoy the cool, surname-y style, you could also consider Boone, Wilder, Mack, Adair, Boyd, and Briggs as less popular alternatives.

Caius is classical and serious but also has a simple, joyful quality. There was a third century pope named Caius, as well as an early Christian writer, several Shakespearean characters, and a Twilight vampire. We would pronounce the name to rhyme with eye-us though at Cambridge University in England, where it's the name of a college, it's pronounced keys. 
 Nickname Cai is a definite asset.

Caius

This up-and-coming single-syllable name has a few famous bearers, including baseballer Cale Iorg and Canadian hip-hop musician Cale Sampson. Sounding like Kale, this name also has a crunchy, hipster  vibe.

Cale

Cato conjures up images of ancient Roman statesmen and southern antebellum retainers; it could have revival potential, with its 'O' ending and the current interest in the names of Greek and Roman antiquity.
 The Roman statesman known as Cato the Elder was born Marcus Portius, the Cato added in tribute to his natural sagacity, practical wisdom and political expertise.
 Cato appears in Shakespeare's Julius Caesar and, to go from the sublime to the ridiculous, in the Pink Panther movies--and Kato was The Green Hornet's valet. Cato is also a 21st century Hunger Games name, which could do more to spur its popularity than all its past history.

Strong, charismatic, and sleek, Elias has followed in the footsteps of Elijah and Eli to become a popular choice among parents today. 
While it may sound cool and fresh, Elias is a name with history and substance. It is the Greek form of the name Elijah, meaning “Yahweh is God,” and was used in both the Greek New Testament and medieval tales. Elias was then given to early saints, to honor the miracles and work of the popular Biblical figure. 
Revived by Puritans in the 18th century, notable namesakes include the inventor of the sewing machine, Elias Howe, writer Elias Canetti and Walter Elias Disney. 
Felix Mendelssohn composed a popular oratorio named “Elias”, while Sir Walter Scott, Anthony Trollope, and Thomas Hardy all have characters called Elias in their novels, giving the name literary and classical charm. 
In the US, Elias has seen significant usage from the 90’s onwards with its popularity doubling during the 2010’s. Given to over 6000 boys each year, Elias continues to climb the charts and has overtaken Eli as a go to El- choice. 
While still outranked by Elijah in the US, across Europe and South America, Elias is the preferred form. Popular in Sweden, Germany, Switzerland, Uruguay, and Mexico, Elias travels well. 
The name has been chosen for characters in the popular horror podcast, The Magnus Archives, Cassandra Clare’s trilogy “The Infernal Devices”, and the TV series “Person of Interest.” Elias has the celebrity seal of approval too, with singer Michael Bublé, actor Robert Downey Jr, tennis player Boris Becker and actress Barbara Becker choosing to use it for their sons. 
Handsome and refined as it is, the main problem with Elias is deciding whether you want to use it, or keep Elijah, Eli, Elliot, Elio, Eliza, Elizabeth, or Elise in the running. To avoid the problem, you could go with similar but lower ranking Tobias, Linus, or Ozias.

Elias

Everett is a preppy but outdoorsy name, with wintery New England vibes. In the last decade, it’s had a leap in popularity, perhaps because of its similarity to trendy girls’ names like Ava and Scarlett, or perhaps because it offers a fresh alternative to 90’s style Evan and Brett. 
 
Despite its sleek, sharp sounds, Everett’s meaning lends it some rugged charm. An English variation of the German Eberhard, it means “brave as a wild boar”.
 
George Clooney and Dermot Mulroney drew attention to the name when they played Everetts on screen back in the 2000s. More recently, Everett Ross from Marvel’s Black Panther, and Everett Acker from the television series Breaking Badshone a spotlight back on the name. 
 
Everett feels fresh and contemporary, fitting into the trend of surnames-as-given-names and getting cool points from its fashionable V sound. But it also a name with a history. It ranked in the US Top 100 at the beginning of the 20th century, offering it a sense of solidity. 
 
Now, it’s revived and more loved than ever, with 4000 parents choosing it for their sons each year. Gentle but sophisticated, wild but refined, Everett could become an even more poplar choice in the future. 
 
If the sound of Everett appeals to you but the popularity doesn’t, you could consider Barrett, Truett, Beckett, Merritt, or Garnett. If its style intrigues you but you want something more unique perhaps Everest, Wilder, Patton, Roscoe, or Huxley could be a place to start.

Forrest is one of the earliest appealingly sylvan, outdoorsy choices, borne by newsman Sawyer, actor Whitaker, and football Hall of Famer Gregg. Forrest Gates was a character on "Buffy the Vampire Slayer."
 Forrest was steadily on the US popularity list until 2003, reaching a high of Number 175 in 1913, and then received a somewhat surprising blip after the release of "Forrest Gump." It started rebounding again in 2013, when it reentered the Top 1000 as one of the fastest-rising names on the list.
 Early Forrests were named in honor of Confederate General Nathan Bedford Forrest, head of a famous cavalry force, who advised 'Git there fuster with the mostest men.'

Jasper originated as a variation of the Latin Gaspar, which ultimately derived from the Persian word ganzabara, meaning "bringer of treasure." As a given name, Jasper’s etymology is unrelated to that of the gemstone, which comes from a Semitic word meaning "speckled stone." Jasper is the usual English form for one of the Three Wise Men who brought gifts to the infant Christ according to medieval tradition and appears in the Bible as a reference to the stone itself in Revelations 4:3.
 
Jasper has a lot going for it—it's been rocketing up the ranks in the US, after long being considered a posh and charming name in England. Distinctly masculine, Jasper represents a variety of quartz—one of the few gem <a href="https://nameberry.com/boys-names">names for boys</a>—and is the first name of the great modern artist Jasper Johns. Our only caveat: Jasper is a favorite of a lot of hip parents, and has gotten even more popular since its strong appearance in the Twilight books and movies.
 Jasper has considerable literary cred as well, appearing in works by Sir Walter Scott, James Fenimore Cooper, Thackeray, and Thomas Hardy--as well as Stephenie Meyer. 
 Casper/Caspar is the German version.

Jasper

Kai is an internationally flexible name with many possible origins and meanings, growing in popularity in the US and a diverse range of European countries.
 
In the US, the name Kai is most commonly referred to as being of Hawaiian derivation, meaning "sea." In Europe, Kai is largely considered to have Frisian origin as a diminutive of the name Kaimbe, meaning "warrior", or as a short form of Gerard "brave spear". 
 
Kai is also found as an independent name in African, Chinese, Turkish and Native American cultures. Kai is a strong, evocative multi-cultural name that packs a lot of power in its single syllable. 
 
Famous as the name of the boy enchanted by the fairy-tale Snow Queen, Kai was chosen for her son by actress Jennifer Connelly and as a middle name for son Samuel by Naomi Watts and Liev Schreiber. 
 
Kai is popular with Berries as both a first and middle name choice. Perhaps because of its international familiarity, Kai is popular in video games. Its most prominent namesake is Danish-born jazz trombonist Kai Winding.
 
Kai ranks in the US Top 1000 for girls, but is used more than 90 percent of the time for boys. Donald Trump, Jr. has a daughter named Kai Madison and Gigi Hadid and Zayn Malik named their daughter Khai in 2020.

A friendly Irish and Persian name chosen by Geena Davis for one of her twin boys, whose father is Iranian.

Irish and Iranian has to be one of the most diverse pair of roots of any name. Kian can be a variation of the Irish Cian, very popular in its native land. While Cian is fairly rare in the US, Kian has been rising through the ranks for the past two decades. The Irish Cian or Kian is pronounced with the emphasis on the first syllable, KEE-en, rhyming with Ian.

The Iranian Kian is pronounced kee-AHN, like the first two syllables of Keanu as in Reeves.

Spelled Kian, the name is popular throughout the English-speaking world as well as in Germany, Sweden, and Switzerland, but it's impossible to say whether the parents choosing it are going for the Irish or Persian version. Some undoubtedly don't care and simply like the name, no matter what its origin.

Leif is one of the most recognizable <a href="https://nameberry.com/baby-names/173/scandinavian-names">Scandinavian names</a>, thanks to Icelandic explorer Leif Erikson, and is still one of the best, with a pleasant aural association with the word leaf. 
 Leif Erikson, son of explorer Eric the Red, was the first European to land in North America--some five hundred years before Columbus. Centuries later, the name became associated in the U.S. with 1970s teen idol Leif Garrett, the name peaking on the charts at Number 654 in 1970, dropping off completely in 1987. It climbed back onto the Top 1000 in 2014.
 Pronounced LAYF in its Scandinavian milieu, Leif and Lief are sometimes pronounced as Leaf in English-speaking countries. Joaquin Phoenix was for a time known as Leaf, in keeping with the <a href="https://nameberry.com/list/329/nature-baby-names">nature names</a> of his siblings.

Levi, lighter and more energetic than most biblical names, with its up vowel ending, combines Old Testament gravitas with the casual flair associated with Levi Strauss jeans. 
 Now it's being rediscovered in a major way—Levi has been shooting up the charts in recent years. Extremely popular in the US, it's also a Top 100 name throughout the English-speaking world as well as in a diverse range of countries from Germany to Brazil.
 
In the Old Testament, Levi was the third son of Leah and Jacob, from whom the priestly tribe of Levites descended; in the New Testament, Levi was Matthew's given name before he became an apostle. It is suspected that Levi derives from the Hebrew word yillaweh, meaning "he will join." 
 Levi received a lot of attention as the sons of Matthew McConaughey, Sheryl Crow and Sara Gilbert.
 In the Thomas Hardy novel Far from the Madding Crowd, Levi Everdene is the father of the heroine.

Levon is a related name.

Pierce Brosnan inspired the return of the name in the 1980s, and it's still going strong. Pierce is actually pronounced differently from father name Piers, which has more of a z sound at the end.

About 500 baby boys were named Pierce in the US last year....and about 30 baby girls.

Wyatt has been hot, which is to say cool, for several years now. With its easy Wyatt Earpish cowboy charm, it's relaxed but still highly respectable. 
 Wyatt is a lot more classic a name than you might guess. It's one of those names that just misses ranking in the Top 1000 for its entire 140+ year history.
 
Wyatt was derived from the Medieval English name Wyot, itself a form of the given name Wigheard, with wig meaning "war" and heard, "brave." Wyot, along with variations Wiot and Gyot, were also used by the Normans as nicknames for names such as William. Wyatt became a patronymic surname later in the Middle Ages.
 
Wyatt got one of it first modern pushes when Peter Fonda played a Wyatt in the seminal film "Easy Rider. Goldie Hawn and Kurt Russell were among the first celebs to use Wyatt for their son born in 1986; more recently, singer Sheryl Crow chose it for her baby boy. Wyatt is also the name of the alter ego of a central character on the HBO show Westworld.
 
And even more recently, Mila Kunis and Ashton Kutcher used the name for their baby daughter, perhaps pushing the name across the gender line, though it has a long way to go before it's considered unisex; it's still much more popular for boys than it is for girls. Does the baby name world have Wyette in its future?
 
Wyatt is also enjoying a wave of current popularity in Canada.
