Milo is most commonly considered to be Germanic name derived from the Latin word miles, meaning "soldier." However, there is evidence to suggest it also may have independently spawned from the Slavic root milu, meaning "merciful." Milo predates brother name Miles, a variation that evolved when the name immigrated to the British Isles in the Middle Ages. Mylo is an alternate spelling.

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.

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 boy names. Atticus entered the US Top 1000 in 2004 and is a firm Nameberry favorite.

Atlas is one of those names that was previously thought too powerful for a baby boy, who would have to be strong enough to carry the world on his shoulders. Now Atlas has joined the pantheon of Greek and Roman god and goddess names in the realm of possibility, along with Mars, Zeus and Apollo.

Bartholomew is an apostle's name that's been out of favor for centuries but might appeal again to the parent in search of an old but rare choice. The challenge could be to avoid the Simpson-ish nickname. That character, by the way, has the full name of Bartholomew JoJo Simpson, and creator Matt Groening came up with Bart as an--uh oh--anagram for brat. Two old alternate nicknames are Barty and Tolly.

Leo is a strong-yet-friendly name that was common among the Romans, used for fourteen popes, and is now at its highest point ever in the US thanks in part to Leonardo "Leo" DiCaprio.

The bright, playful Micah feels like the middle ground between the safe, solid qualities of Michael and the flair and energy of Luca. Both Biblical and stylish, Micah is proving popular among parents today.

Reminiscent of the Old West, with rugged charm and a gentle, easy-going feel, Wesley has long been a staple on the US charts.

With a touch of celestial power, a hint of clunky charm, and the totally cool -o ending, Cosmo may well be finally shaking itself free of both the Seinfeld association (which made it a punchline of a joke) and the cartoon fairy association from The Fairly OddParents. In fact, it is in the Top 1000 in the UK and a favorite on Nameberry.

With many British names invading the Yankee name pool, the sophisticated Alistair could and should be part of the next wave. It debuted in the US Top 1000 in 2016. You have a triple choice with this name--the British spell it Alistair or Alastair, while the Scots prefer Alasdair--but they're all suave Gaelic versions of Alexander. Adopted by the lowland Scots by the seventeenth century, the name didn't become popular outside Scotland and Ireland until the twentieth century.

Cillian is one of the native Irish names that, along with Aiden and Declan, is becoming an unlikely favorite in contemporary America. The Killian spelling has been more popular in the US, but Cillian's star is rising, perhaps thanks to Irish actor Cillian Murphy, star of Oppenheimer and Peaky Blinders.

Dominic comes from the Latin name Dominicus and is common in the Roman-Catholic community. In the past it has been given to boys born on Sunday—the word "Sunday" in languages including Spanish and French shares Dominic’s roots. In use in the English-speaking world since medieval times, its most famous bearer was St. Dominic, founder of the Dominican order of monks in the thirteenth century.

This appealing name has a good chance of catching on due to the popularity of Ewan McGregor, and the trend towards Gaelic names in general. Pronunciation is YOO-un.

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.

Sullivan is a jaunty Celtic three-syllable name, with a real twinkle in its eye. It was immortalized in the 1930s classic film Sullivan's Travels and was chosen for one of Patrick Dempsey's twin boys. Nickname Sully is equally jaunty.

Gideon is a no-longer neglected Old Testament name, but still makes an excellent choice for parents looking to move beyond such overused biblicals as Benjamin and Jacob. In the Old Testament, Gideon was a judge called on by God to rescue the Jews from the Midianites, and the name was popular among the Puritans.

Lysander is a distinctive Greek name that could be thought of as a more creative cousin of Alexander. In ancient history, Lysander was the name of an esteemed Spartan naval commander and his literary cred comes from one of the two star-struck young men in Shakespeare's A Midsummer Night's Dream, as well as one of the twin sons (the other being Lorcan) of Luna Lovegood, whom we learn about in the Harry Potter epilogue.

Evander is a name that could build on the popularity of shorter form Evan, and could work and play well with schoolmates like Zander and Xander.

Jaunty and raffish, Rafferty is one of the most engaging of the Irish surnames, used by Jude Law and Sadie Frost for their son. Fortunately, it doesn't still go by its original form: O'Raighbheartaigh.

Rufus is a rumpled, redheaded (it was the nickname for red-haired King William) ancient Roman name popular with saints and singers (e.g. Rufus Wainwright); now, Rufus is on the cutting edge of cool.
