Adriano is a dashing Italian name which gets around the possible gender confusion of Adrian.

Adriano

Alexius

Andreas is a beautiful name, with the patina of an Old Master painting, one that could make a dashing namesake for an Uncle Andrew. 
 In Europe, Andreas is currently in the Top 20 in Norway and is also popular in Denmark, Sweden, Germany, and Austria.
Some other international variations of Andrew you might want to consider — Andre, Andrei, Andres, Andrea, and Anders.
 Notable namesakes include photographer Andreas Feininger. One not-so-pleasant association: the San Andreas fault line in California.

Andreas

Antonio is a Shakespearean favorite -- the Bard used it in no less than five of his plays, and has long been a ubiquitous classic in Spanish-speaking countries, where the nickname Tonio is also prevalent. Antonio is also among an elite group of perennially popular names in the US, where it has always been among the boys' Top 1000 since baby name record-keeping started in 1880.

Antonio

Atticus, with its trendy Roman feel combined with the upstanding, noble image of Atticus Finch in To Kill a Mockingbird, is a real winner among <a href="https://nameberry.com/boys-names">boy names</a>. Atticus entered the US Top 1000 in 2004 and is a firm Nameberry favorite. 
 
The reason for the popularity of Atticus is less its ancient roots than Atticus Finch, the upstanding hero of To Kill A Mockingbird.. In fact so many people have been inspired by the character embodied by Gregory Peck that Atticus Finch was voted the greatest hero of American film by the American Film Institute. Harper Lee's recently-released novel Go Set a Watchman paints Atticus Finch in a less flattering light, though that doesn't seem to have impacted the rising popularity of the name.
 
Atticus derives from the Greek Attikos, meaning "from Attica," the Ancient Greek region that contained Athens. Atticus is a literary name in more ways than one. Before it became synonymous with Atticus Finch, the name Atticus was associated with Titus Pomponius Atticus, a Roman literary figure.
 Daniel Baldwin and Isabella Hoffman were ahead of the curve when they chose Atticus for their son born in 1996; since then Summer Phoenix and Casey Affleck named their little boy Atticus, and Tom Dumont made it the middle name for his son Rio.

Atticus

Since Aurelius was given the supermodel seal of approval by Elle Macpherson, this is one of the Roman emperor names, like Augustus, now in the realm of possibility. Like the female Aurelia and Aurora, Aurelius has a particularly warm golden aura.
 In ancient Roman history, the name is associated with Marcus Aurelius, a Roman Emperor from 161 to 180 AD, the last of the so-called "Five Good Emperors." He is also considered one of the most important Stoic philosophers. He granted his name en masse to citizens of the empire who didn’t have one, making Aurelius a common and default nomen (family name) towards the later years of the empire.

Aurelius

Joyful-sounding name that makes a really original option.

Caio

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

Carlos is the Spanish and Portuguese variation of Charles, which has been used in solid numbers in the US for as long as data has been kept. Carlos has never fallen out of the Top 600, but peaked from the 70s-early 2000s. Today Carlos is still within the Top 200. 

Notable namesakes include musician Santana, writers Fuentes and Castaneda, and numerous athletes. Carlos Irwin Estevez is the birth name of Charlie Sheen.

Carlos

Charles derives from the Germanic name Karl, meaning "man" or "freeman", and is a royal name in multiple European countries. A famous early bearer is Charlemagne, King of the Franks and Lombards and then Roman Emperor in the 8th-9th centuries. 
 
The word for "king" in several languages, including Slavic, Russian, and Polish, came from Charles. And, of course, Charles III is the current king of Great Britain.
 
Charles is a longtime traditional favorite that was in the Top 10 until the 1960s. Though not as popular as it once was, it's still a widely used name. 
 
The most fashionable form of Charles today is Charlie, used almost equally for girls and boys. And of course, Charlie or Charley is still used as a short form for Charles, along with the old school Chuck and new school Chas/Chaz.
 
Lately, Charles has been resuscitated by many celeb parents, from Jodie Foster to Russell Crowe, honoring a distinguished history dating back to the emperor Charlemagne—the original Charles the Great. 
 
Charles has been so well used for so long that it is virtually faceless—it can conjure up anyone from Dickens to Chaplin to Bronson. It has been an elegant royal name—designating both Bonnie Prince Charlie, leader of a 1745 rebellion, and the present king, as well as previous kings of France, Spain, England, Portugal, and Hungary. 
 
Among the well used international versions of Charles: Carl, Carlo, Carlos, Karel, Xarles, Charlot, and Siarl.

Charles

Davis is a fresh way to say David. Some sources define it as "son of David," but we see it as a surname spin on the original. While David is an everyman name, Davis has some creative edge -- and still gets you to the classic guy nickname Dave. 
 
Davis can be a good way to name a boy after grandpa David; Davies, Davison or Davidson will also do the trick.
 In the TV show One Tree Hill, the Sophie Bush character gives one of her twins her maiden name of Davis. Davis Guggenheim is an Oscar-winning director and documentarian, married to Elisabeth Shue.

Davis

The energetic Diego is rising rapidly along with a lot of other authentically <a href="https://nameberry.com/baby-names/161/spanish-names">Spanish baby names</a> that work perfectly well with surnames of any origin. 
 Possibly a derivative of Santiago, Diego is a Sevillian saint, and one notable cultural namesake is Mexican painter Diego Rivera.

Diego

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

Elio is a sunny and spirited Italian and Spanish name that makes a great crossover prospect, which could catch on as Enzo has. Elio is also currently popular in France, ranking in the Top 250.

Elio

Emiliano and Emilio are the appealing Latinate version of Emil. Emiliano Zapata Salazar was a leading figure in the Mexican Revolution, who helped establish modern Mexico.

Emiliano

Dashing and popular Italian and Spanish favorite, as is Emiliano. With the popularity of girl names Emily and Emilia and of Italian names for boys, this one is sure to receive more attention.

Actor Emilio Estevez heightened the profile of this name.

Emilio

Since this was the name chosen by the current Roman Catholic pope, Francis has come into the spotlight.
 The name, which was in the Top 10 at the turn of the last century, has been pretty much confined to Irish and Italian Catholics -- think F. (Francis) Scott Fitzgerald, Francis Albert Sinatra, Francis Ford Coppola -- for decades, and still has a somewhat starchy feel. But with its similarity to the increasingly popular female Frances, and its recent newsworthiness, we can see it making a possible comeback beyond those worlds. And in fact, the name has risen a bit in the charts since its all-time low of 680 in 2009.
 Animal-loving parents might be inspired by the connection to Saint Francis of Assisi (born Giovanni), who was said to be able to communicate with animals and was made the patron saint of ecology. Another Francis, Saint Francis de Sales, is the patron saint of writers and editors.

Francis

Francisco is one of the more popular <a href="https://nameberry.com/baby-names/496/spanish-names-for-boys">Spanish names for boys</a> in the US, which is unsurprising given its popularity back in Spain and Portugal as well as Latin America, coupled with its classic status. It also has a cool hipster vibe to it, given the reputation of the city of San Francisco.

Francisco

A classic Italian name still heard in the Italian-American community. Once tainted by the association with the Spanish dictator, it's now more likely to call up actor James Franco. 
 The bright o ending and the popularity of Pope Francis could increase the appeal of this name.

Franco

Giorgio as is rich in meaning and history as George, but with more Italian flair. It's a consistent Top 50 hit in Italy, and with Italian boy names like Gianni and Lorenzo rising through the charts, could be another one to add to the mix.
The best-known modern bearer is fashion designer Giorgio Armani.

Giorgio

When Harrison is too much, but Harry isn't enough, try this stylish surname name with a touch of British flair. It briefly reentered the US Top 1000 for the first time since 1988 in 2016, but has since dropped just below the radar again.

 Harris is wildly popular in Scotland, where it is also a geographical name, belonging to one of the largest of the country's many islands. Harris consistently ranks in the Top 10 for boys in Scotland, and in the Top 300 in neighboring England and Wales.

 Harris is also an extremely popular surname, among the Top 25 <a href="https://nameberry.com/blog/top-last-names-in-the-us">most common last names in the US</a>.. A famous current bearer is Kamala Harris, who in 2021 became the first ever female vice president of the US, as well as the first African American and first Asian American vice president.

Harris

James is one of the classic Anglo-Saxon names, a stalwart through the ages that is more popular—and yes, stylish—than ever today. It recently came out Number 1 in a poll of America's favorite boys' baby names, and is the most common male name, counting people of all ages, in the US.
 James, which reentered the Top 5 in 2016, is a current favorite among fashionable parents looking for a baby name that has both style and substance. Like Henry and Theodore, it manages to combine these two stellar qualities.
 
An English derivation of the Hebrew name Jacob, James is biblical (the name of two apostles in the New Testament), royal (kings of both England and Scotland), and presidential (with more U.S. Chief Executives -- six -- than any other name). The name James is also shared by countless great writers and entertainers.
 
There are fewer Jimmys, Jimbos or even Jamies these days; the most fashionable form of the name is James itself. Several stylish celebrities have chosen it in recent years for their sons, including Sarah Jessica Parker and Matthew Broderick, Liz Phair, Colin Farrell and Isaac Hanson. Brendan Fehr thought out of the box and named his daughter James, which has now become a fashionable middle names for baby girls..
James has some interesting foreign variations: Diego and Jaime (Spanish), Jacques (French), Giacomo (Italian), Hamish (Scottish), Jaako (Finnish), Seamus (Irish), Jaap (Dutch) and Jago (Cornish).
 Along with being one of the most popular first names in the US, James is also one of the <a href="https://nameberry.com/blog/top-last-names-in-the-us">most common American last names </a>.

James

Though there were two apostles named Judas, everyone remembers the one who betrayed Jesus, and the name has been permanently shunned. 

Judas

What with Paul Simon's classic lyric about Julio down by the schoolyard and several distinguished bearers, this livelier Spanish version of Julius is completely familiar to the non-Hispanic community and would make a great choice for a bicultural family. NFL Atlanta Falcons star Julio Jones bears this name.

Julio

Can Linus lose its metaphorical security blanket and move from the Peanuts page onto the birth certificate? We think it has enough charm and other positive elements going for it for the answer to be yes.
 In Greek myth, Linus is both a musician and poet, the inventor of rhythm and melody who taught music to Hercules. In the Christian era, Linus was the name of the second pope, Saint Peter's successor, while in modern times chemist Linus Pauling was awarded the Nobel Prize twice.
 Humphrey Bogart as Linus Larrabee won the heart of Audrey Hepburn in Sabrina, and Matt Damon played Linus Caldwell in three of the Oceans movies. 
 Linus is currently in or around the Top 50 in Germany, Sweden and Norway, and is one of the most popular boys' names on Nameberry.

Linus

Kate and William shocked the world when they announced that they'd named their third child Louis -- Prince Louis Arthur Charles, to be more precise. But we've been predicting a comeback for this classic name for a long time. Both Louis and Lewis are already quite popular again in Britain. And several other high-profile parents —like actors Sandra Bullock and Bill Pullman— beat the Duke and Duchess to the punch by naming their sons Louis years ago. While the pronunciation in Britain is normally the French LOO-ee, in the US the final S is often pronounced. To get around the pronunciation confusion, many parents especially In the UK, go with the forms Louie or Lewis, with Louie ranking even higher than Louis. Lewis is in the Scottish Top 10.

Louis

Lucas is a Top 10 boys' name with a slightly-less-popular almost-identical twin brother, Luke. Like Elijah and Elias, Lucas and Luke come from the same root and have the same meaning and so feel even more popular than they are.
 
The Latin derivation of the Greek Loukas, the name's meaning references Lucania, an ancient territory in Southern Italy. Along with Luke, Lucas is also related to international name star Luca, while the similar Lucius and Lucian derive from a different root and have a different meaning.
 Lucas is enjoying tremendous international success, popular throughout the English-speaking world as well as in a diverse range of countries throughout Europe and Latin America, including Scandinavia, France, Germany, Spain, and Brazil. This makes Lucas the perfect choice for a cross-cultural family.
 Lucas has long been a favorite of TV scriptwriters, from the early black-and-white days of The Rifleman (Chuck Connors as Lucas McCain) to the schoolteacher series Lucas Tanner to the more contemporary One Tree Hill. On the literary side, the name appears as Lucas Beauchamp in William Faulkner's Intruder in the Dust and Light in August.
 Lucas Cranach was an important German Renaissance painter and printmaker; Lucas Samaras is an eccentric Greek-born American contemporary artist. Some will associate the name with director George Lucas.

Lucas

Lucius is an old Roman clan name that has lots of religious and literary resonance, yet is still vital today. It was the name of three popes, appears in several Shakespeare plays, and, like all the names beginning with 'luc' relates to the Latin word for light.It was one of a limited number of forenames used in ancient Rome, and because of its meaning was often given to boys born at dawn.
 In the Bible, Lucius is the name of three people; Shakespeare used it for the son of Titus in Titus Andronicus, a young servant of Brutus in Julius Caesar, a lord in Timon of Athens and a Roman general in Cymbeline.
 Other fictional bearers of the name can be found in Le Morte d'Arthur, The Golden Ass, Ralph Ellison's Invisible Man, Faulkner's The Reivers, Batman, Talladega Nights, and The Incredibles. Lucius Malfoy, the father of Draco, is a Harry Potter villain, and other Luciuses have been portrayed on screen by Morgan Freeman, Joaquin Phoenix and Luke Wilson.
 Real-life namesakes include renowned World War II General Lucius B. Clay, and writer, photographer, and bon vivant Lucius Beebe.

Lucius

Another culture's slant on Mark, sometimes associated with former president of the Philippines Ferdinand Marcos and his shoe-collecting wife, Imelda. 

Marcos

Matthias is the ancient Biblical form of Matthew, widely used along with brother Mathias in the US for the past 20 years.

This New Testament name -- he was chosen to replace Judas Iscariot as an Apostle -- is found in several European languages and cultures. In every language from Scandinavia to France to Spain, the name is pronounced ma-TEE-us, but in the US it might be pronounced with a long I in the middle -- ma-TYE-us.

Mathias

This attractively energetic Italian version of the classic Matthew is primed to move further and further into mainstream American nomenclature. Mateo is technically the Spanish version, but many parents in the US use the two spellings interchangeably. 
 
In the US, about 12,000 baby boys were named Mateo, Matteo, or Teo in 2021, vaulting the name in all versions into the Top 10. Mateo alone, by far the most popular version, lies just outside the Top 10.
 Actor Colin Firth has a son called Matteo, as does Ricky Martin; the Benjamin Bratts and Tom Colicchios have boys named Mateo. We're sure that both these spellings will keep climbing in tandem, sharing the possibility of the lively nickname Teo.

Matteo

Miles, which has a permanent veneer of cool thanks to jazz great Miles Davis, is a confident and polished boys' name that's an American classic. Always ranking in the US Top 1000, it's been drifting up the charts for the past half century but has never been TOO popular.
 
Miles is a favorite of celebrity baby namers, given to their sons by Elisabeth Shue, Mayim Bialik, Larenz Tate, Joan Cusack and Lionel Ritchie. It also makes a great honor name for all the Grandpa Michaels out there.
 Miles was the name of the first translator of the Bible into English--the English monk Miles Coverdale, which is also the name of a character in Hawthorne's The Blithedale Romance. Miles Hendon figures in Mark Twain's The Prince and the Pauper, and Miles was one of the young children in Henry James's The Turn of the Screw. Miles--or Myles--Standish was the leader of the Pilgrim fathers.
 Miles has also been a favorite movie and TV character name from the days of Murphy Brown to 24 and Avatar.

Miles

Nicholas is derived from the Greek Nikolaos, a name that evolved from the components nikē, meaning "victory", and laos, "people." It shares origins with Nike, the name of the Greek goddess of victory. Nicholas is also a New Testament name that is well-used in literature, such as in Dickens's Nicholas Nickleby.
 
And then there's St. Nicholas who, in addition to bringing bags of toys once a year, is also the patron saint of schoolchildren, mechanics, sailors, scholars, brides, bakers, travelers, and Russia, where the name was a star of the czarist dynasty.
 
Nicholas, though it has lost some ground (it was in the Top 10 from 1993 to 2002), is still a popular classic that would make an attractive, solid choice.
 
Along with this historical depth, Nicholas, and nicknames Nick and Nicky, project an aura of masculine panache, and has long been a favorite of writers for rich boys, Romeos, thugs and detective characters.
 
Offshoots Cole and Colin have long had lives of their own. Short form Nico is hot and getting hotter.

Nicholas

Richard is far from fashionable, but Ricardo is one of the most popular <a href="https://nameberry.com/baby-names/496/spanish-names-for-boys">Spanish names for boys</a> in the US. And it does sound far more appealing that the English version.

Ricardo

Sleek and smart, with a hint of mystique about it, Silas is a recent addition to the US Top 100. Both mythological and Biblical in origin, Silas joins the ranks of Isaiah, Atlas, Elias, and Sebastian: polished and contemporary feeling names with plenty of history. 
The origins of Silas are debated or perhaps multiple. On one hand, it could a simplified form of the Latin Silvanus, meaning “of the forest.” 
In Roman mythology, Silvanus was the god of trees, and his name was originally bestowed on those who lived in forested areas or who worked with wood. This could bring either a hardy, outdoorsy ruggedness to the name or something more mystical, dark, and intriguing. 
On the other hand, Silas could be a Greek form of the Aramaic Seila or of the Hebrew Saul, meaning “asked for” or “prayed for”. 
Its Biblical roots can then be traced to either Saul, the first King of Israel, or to a companion of Paul the Apostle. Later venerated as a saint, Silas was a leading member of the early Christian community, who accompanied Paul on his second missionary journey. 
Given as an English name from the 17th century onwards, Silas has a rich literary history. Notably used by George Eliot in Silas Marner and by Dan Brown in The Da Vinci Code, Sheridan Le Fanu, Charles Dickens, Robert Frost, Willaim D. Howell, Neil Gaiman, and Mark Twain have also featured a Silas in their work. 
A longstanding favorite and <a href=“https://nameberry.com/popular-names/nameberry/boys”>one of the most searched names on Nameberry</a>, in the ‘real world’, Silas had mostly lingered towards the lower end of the US Top 1000 in the 20th century. 
It did gain some attention in the Netherlands, Denmark, and Switzerland in the 2000’s, but it took until the 2010’s for it to make significant moves in the US. Now, it is trending upwards and given to nearly 4000 babies each year. 
Based on its Nameberry popularity, its status as ancient but still fresh, and its similarity in sound or style to popular Elijah, Isaac, Lucas, and Samuel, Silas could continue to climb the charts. 
If you love it, but don’t want to be part of the crowd, you could consider one of Silas’s relatives, such as Sylvan, Sylvester, or Sylvius; alternatively, Linus, Rufus, Caius, Laurence, or Ozias might appeal as less popular options.

Silas

See the popularity graph below for the name Theo? It's been heading straight uphill since 2010, when it hopped back onto the Top 1000 after a 60+ year absence.
 
Now in the Top 100 in this form, Theo's popularity is even wider given its common use as a nickname for Theodore, which made the Top 10 for the first time in 2022. This might be the generation of Theos.
 
Theo's newfound popularity extends far beyond the US and the rest of the English-speaking world. It's currently a Top 100 name in Germany, Brazil, Scandinavia, and beyond, as well as being a popular choice for pets.
 Theo first made an impact as the name of the only son on "The Cosby Show," earlier it was associated with Vincent van Gogh's supportive brother Theo.

Theo

A solid classic with plenty of history, Thomas strikes the balance between strength and gentleness. A favorite in the UK, a staple in France, and Australia, and never absent from the US Top 100, Thomas feels like a safe bet and a name that fits into any era. 
The Greek form of the Aramaic name Ta’oma, Thomas means “twin.” It came about in the Bible because there were too many apostles called Judas, and so, Thomas became the “twin”, to reflect his close brotherhood with Jesus. 
Known as “Doubting Thomas” due to his initial skepticism of Jesus’s resurrection, he went on to become a martyr, and there was no need to doubt Thomas’s potential as a given name. 
Brought into common usage by the Normans, it was then always among the 5 most common English names for boys at any point between the 13th and 19th century. 
While it has fallen down the US charts in recent years, it remains a familiar and trusted choice. Given to over 6000 boys every year, it has made a steady climb back into the Top 50. 
Across the pond in the UK, both Thomas and Tommy make the Top 30, while Tom, Tommy-Lee and Tommie have made their mark in the Top 1000. 
As a well-established classic, Thomas naturally comes with plenty of noteworthy namesakes. “Thomas the Tank Engine” might appeal to you kids, but there’s also the theologian, Sir Thomas Aquinas, the cardinal Thomas Wolsey, the Founding Father, Thomas Jefferson. the philosopher, Thomas Hobbes, and the writer, Thomas Hardy. 
More recent namesakes for those who aren’t into history include actors Tom Hardy, Tom Cruise, and Tom Hiddleston, singers Tom Parker and Tom Fletcher, Olympic diver Tom Daley, and Thomas Sanders, of YouTube fame. 
A timeless all-rounder, Thomas comes with the intuitive nicknames, Tommy and Tom, which feel sweet for a child but not too cutesy for a grown-up. For more unexpected options, you could try the nature-inspired Moss or Scottish Tam. 
Unlikely to go out of style anytime soon, Thomas is a refined but approachable choice. If the popularity does give you pause, however, you could try the surname-inspired Thompson, or an <a href=“https://nameberry.com/list/492/100-classic-boys-names--below-the-top-1000/all”> underused classic</a> like Marius, Rufus, or Phinneas. 
Alternatively, there is a wealth of interesting variants to ponder, from Italian Tommaso and Scottish Tavish to Croatian Tomo– and for girls, there’s Thomasina, Tomine and Tamsin.
