Alessio, simpler than the related Alessandro, would be a welcome settler here. 

Alessio

Amadeo and Amedeo are both valid Italian forms of the Roman Amadeus, most famous as the middle name of the composer Mozart as well as the title of a movie about him. Mozart's name was actually the Greek Theophilus, but he transformed it to the Latin version. Amadeo is also used in Spain, where it was the name of a 19th century king who was born in Italy.

Amadeo

Old-school Italian name that could find new fans thanks to singer Adele, who chose it for her son after months of baby name mystery.  Angelo is in the same name category as Rocco, the name of Madonna's son, and may get a fresh coat of cool.

Angelo

The name of the ship sailed by Jason in his search for the Golden Fleece is now more often used for starch, trucks, and heavy machinery. 

Argo

Quirky cool Arlo is now well and truly back. Last year it broke into the US Top 200 boy names and consistently ranks among the most popular boy names on Nameberry. 
 Arlo is even more popular in the UK, Australia and New Zealand. Arlo is also one of the top baby names among Nameberry's visitors from leading US cities.

 
Once strongly associated with shaggy singer Arlo Guthrie, Arlo has an animated and cheery feel, thanks to its upbeat o ending. It was chosen by Toni Colette for her son in 2011, which brought the name back into the spotlight. Previously, Arlo was in regular use in the first half of the twentieth century—it was Number 667 in 1915, for example, but it had dropped off the charts in 1944.
 Arlo has many possible derivations along with its Irish and English roots. It may be a shortened form of the Italian name Carlo or the Spanish Carlos, and in Basque-speaking regions it is the word for area. In English, Arlo was used as a place name, Arlo Hill, by Edmund Spenser in his epic poem The Faerie Queene and is thought to derive from the Celtic word Aherlow, meaning "between two highlands."

 A growing number of girls are also named Arlo in the US each year, with a handful more babies of both sexes receiving the Arlow and Arlowe spellings, which take this name more into smart surname territory.

Arlo

Beau suggests someone devilishly handsome, with a large measure of southern charm—a nice image to bestow on your boy. Often solely a nickname in the past, it's now standing firmly on its own. Beau has been on the Social Security list non-stop since 1969.
 Beau also has something of a dapper image, thanks to the fashionable Beau Brummell (born George), which led to the stylish New York mayor Jimmy Walker being called Beau James. Other notable Beaus had more formal names at birth—Beaus Bridges and Biden were both the third sons in their families to carry their fathers' names: Lloyd Vernet Bridges III and Joseph Robinette Biden III.
 P.C. Wren's novel Beau Geste was a major bestseller in its day and was also a popular movie—in that case Michael was the character's birth name. Many will remember that the child of Ashley and Melanie Wilkes in Gone With the Wind was called Beau, and there was also a Beau on the old TV western Maverick.
 And if you want a more substantial name on the birth certificate, try Beauregard.
 Art Garfunkel, Emma Bunton, Wendy Wilson, Jamie-Lynn Sigler, and now Tori Spelling all have sons named Beau.

Beau

Belisario is romantic, dashing, but perhaps a bit too elaborate.  You might consider Belisario a masculine twist on the popular Belle names for girls.

Belisario

A popular name in Denmark, in this country Bo has some cowboy swagger and a lot of substance in its minimal two letters.
In Mandarin Chinese, Bo means "wave".

Joyful-sounding name that makes a really original option.

Caio

The meaning is endearing, but it also feels uncomfortably like a short form for Caroline. Its artistic reference is British sculptor Anthony Caro.

Caro

A cool and rare Welsh nickname, though it may put some people in mind of the Banana Boat Song.

Deio

Devereaux is familiar to many English speakers as a surname but not as a first. It's a habitational name related to the River Eure in France. Mick Jagger has a son with this name in a different spelling, Deveraux.

Eliano

Eliso

Fiery sound and uplifting meaning, but it's also among the Top 100 dog names. Spelled Fiyero, it's the hero of the book and musical "Wicked." 

Fiero

Hugo, the Latin form of Hugh, has more heft and energy than the original -- and of course we love names that end (or begin, for that matter) with an o. This one is especially appealing because it's backed up by lots of solid history and European style.
 Hugo is one of those names that misses by a single year ranking in the Top 1000 for its entire history. It fell off the list in 1948, the height of post-WWII pro-American fervor, before heading back up.
 Hugh has held steady in the middle of the US Top 1000 for more than 40 years now, but we predict might be headed for the kind of popularity it enjoys in the rest of the English-speaking world and many European countries.
 Hugo ranks in or near the Top 100 in countries and cultures as diverse as Sweden and Spain, France and Finland. It's also a favorite boys' name on Nameberry, usually a harbinger of future success in the US as a whole.
 In the seventh Harry Potter novel, Ron and Hermione bestow the name Hugo on their son. Hugo Strange, meanwhile, is a longtime adversary of Batman. 
 Real-life Hugos include Hugo Chavez, the late president of Venezuela, and the fashion world's Hugo Boss. In the more distant past there was the distinguished Supreme Court Justice Hugo Black.
 Trivia tidbit: The annual awards for sci-fi writing are called the Hugos, honoring early genre writer Hugo Gernsback.

Hugo

A name gaining recognition in Australia, based on the huon pine tree which grows in Tasmania.  Boatbuilders especially love this rare wood, which floats well, is resistant to rot, and has a strong pine-y scent.  

Huon

An unusual name heard in contemporary Germany, the Netherlands, and Scandinavia, it's the male version of the more familiar Inga. It's the name of a German god, and attached to German-born soap star Ingo Rademacher--the father of sons named Peanut and Pohaku Zen.

Ingo

Inigo, almost unknown in the U.S., is an intriguing choice, with its strong beat, creative and evocative sound, and associations with the great early British architect and stage designer Inigo Jones. The sixteenth-seventeenth century Jones shared his name with his father, a London clockmaker, who received it when <a href="https://nameberry.com/baby-names/496/spanish-names-for-boys">Spanish names for boys</a> were fashionable in England, especially among devout Roman Catholics.
 Inigo Montoya is a character in The Princess Bride, played by Mandy Patinkin.
 The pronunciation is with short i's and a hard g: IN-ih-go.

Mateo vaulted into the boys' Top 10 in 2023, ranking all the way up at Number 6. Counting Mateo and Teo along with Anglo equivalents Theodore and Theo make this by far the Number 1 boys' name in the US.
 
Mateo is one of the Latinate names that, like Mia and Luca, is becoming popular far beyond its native Spanish community.
 
The Spanish form of Matthew, which derived from the Hebrew name Mattiyahu, Mateo can also be spelled Matteo, technically the Italian variation. Mattiyahu consists of the elements mattan, meaning "gift" and yah, which references the Hebrew God. 
 
Mateo is enormously popular in Spain and Latin America, but it's also a top boys' name in the US along with several other countries in central and eastern Europe. Its approachable spelling and pronunciation for non-Spanish speakers is one reason it's found such widespread favor. Plus it's a fresh spin on dad name Matthew and a shortcut to the stylish short form Teo.

Actor Colin Firth has a son called Matteo, the Italian form; the Benjamin Bratts have a Mateo. 

Matheo is an archaic Spanish spelling, although it is used in France as Mathéo.

Oliviero

Orlando, the ornate Italianate twist on the dated Roland, with a literary heritage stretching back to Shakespeare and before, has appealing book-ended o's, and is open to combination with almost any last name, a la British actor, Orlando Bloom.
 Orlando has an impressive literary résumé, including the poem "Orlando Furioso,", Handel's opera "Orlando", Shakespeare's As You Like It and Virginia Woolf's gender-bending novel. Most recently, Orlando was a character in The Wire.
 Orlando Bloom's name was inspired by that of the sixteenth century composer, Orlando Gibbons. It is also the first name of several outstanding athletes--including Orlandos Woolridge, Cabrera and Cepeda, and is, of course, a place name, home of Disney World in Florida.

Orlando

Cooler and rarer than Pedro, but also has a slightly industrial sound. 

Perico

It wasn't so long ago that Romeo was considered as outre for an American baby as Casanova or Cupid. But that really changed when David and Victoria Beckham chose it for their second son in 2002, a path followed by Jon Bon Jovi.
 Romeo was not invented by the Bard, but was taken from his source material for the play.
Some sources say it descends from that of Romulus, one of the twin sons of Mars.

Romeo

Ruperto

Silvanus was the Roman god of the forests and is also an alternate name in the New Testament for Silas.  Relatives include Silvio, Silvius, and Sylvia.

As commonly heard in Rome, Italy, as Steve is in Rome, New York. With the accent on the first syllable, Stefano has a lot of charm.

Stefano

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

Tiago, also spelled Thiago, is a popular Portuguese boys' name derived from the more formal Santiago but these days usually used on its own. English speakers won't intuitively get the pronunciation but this might be a creative way to honor an ancestral James or Diego.
