Egyptian mythology place-name with an intriguing sound and appealingly peaceful meaning. Update for Aaron?

Aaru

Arek

Italian, Portuguese and Spanish variation of Arthur that makes the original feel more romantic and dashing.

Arturo

Ax makes a somewhat threatening short form of the popular Axel, given to more than 3000 baby boys last year. It can also be used on its own, though it usually isn't. There were, however, seven baby boys named Axe in the US in 2015.

Macho to the max.  But with the rise of x as a fashionable letter anywhere it appears in a name, ala Jaxson or Maxon, we may be hearing more of Axton.

Axton

Derived from the Scottish Gaelic bàn, meaning "white, fair". It's also a name in J. R. R. Tolkien's fictional Elvish language, in which it means "beautiful".

Bain

Brandt

Can be used either with or without the addition of Mac. 

Callister

Anglicized spelling of a county in Ireland, sometimes considered a variation of the Breton Kavan or of Kevin.  Depending on your viewpoint, may make a fresh Kevin substitute or a choice that will drive you mad explaining that, no, it isn't Kevin.

Cavan

One instance where a phonetic spelling might be better. 

Creighton

This evocative short name is suddenly chic — it was recently chosen by Jennifer Lawrence for her baby boy. JLaw's son's name honors Cy Twombly, the influential mid-century American artist. Born Edwin Parker Twombly Jr., both Cy Twombly and his father shared a nickname after baseball player Cy Young (himself born Denton True Young).
 
We foresee Cy heating up in a big way, along with other Cy- names like Cypress, Cyan, and Cyra.

Because the legendary Faust sold his soul to the devil, few parents would choose this for a child, although Fausto is commonly heard in Italy and Spain. 

Faust

A key figure in Norse legend and a traditional Scandinavian favorite making inroads here.

Gunnar

Iago, the villain of Shakespeare's Othello, was so treacherously evil that his name has hardly ever been heard offstage. Try the much-more-benign Inigo.

Iago

A new-style name based on Kyle and a cousin of Dylan, in spelling if not sound or image. Currently in the US Top 600, it is given to more than 500 boys each year.
 
 While its invented status means it's hard to pin down a solid meaning, it could be said to mean "little Kyle", with -an making it a diminutive (as in the case of Aidan, "little fiery one"). Alternatively, "lan" can signify "land", generating the meaning "Kyle's land" or "land of narrow channels and straits" if considering the meaning of Kyle.

Kylan

Kyven

Kroy

Unlike Pearl and Ruby and more like Jasper, this gem name works well as a boys name. With its strong final X, it feels similar to Alex, Phoenix, Jax, and Rex, while the shiny black quality of the stone feels reminiscent of Orion. Chosen by musician Iggy Azalea for her son in 2020, it has accelerated up the charts and now sits just outside the Top 300.
 
Derived from Greek, the word onyx means "claw, talon, or nail" due to its mythological creation story, in which it formed when Cupid trimmed Venus's fingernails. As a gemstone, it is said to protect against nightmares and improve concentration, though it can also be associated with bad luck and sadness. 
 
Nevertheless, with its sharp, fresh sounds and its cool, polished feel, Onyx is currently a fashionable choice given to more than 1000 boys - and an increasing number of girls - each year.

Onyx

Raylan, one of an uncountable number of two syllable, surname-like <a href="https://nameberry.com/boys-names">boys’ names</a> end in n that are in style these days, is inspired by Raylan Givens, the cowboy hat-wearing U.S. Marshall created by writer Elmore Leonard and starring in the television series Justified. The Ray part of the name is of course a traditional choice -- it's usually said to mean "wise" -- but the lan takes it out of Old School Raymond territory. Other variations include Raylen, Raylon, Rayden and so on. The name is also sometimes given to girls, but not nearly as often as it is for boys.

Raylan

An international variation of Ronan primarily found in Brazil.

Renan

Common Russian name of one of that country's most beloved saints, known for his kindness and gentility. 

Sergei

Evoking the image of a shady glen, Slade could make a distinctive middle name. It entered the Top 1000 in 2007, and has been seen as a character name on the TV show "Smallville."  It's also a name that pops up in comic books and video games.

Slade

Striker is one of the new gang of boys' names that have two syllables, end in -er, spring from words, and have a macho, even aggressive meaning and image.  Other examples include Breaker, Heller, and Wilder.  Do the world a favor and desist.

Striker

Thierry, which is very popular in France, would make an interesting import; it's somewhat familiar through designer Thierry Mugler and international soccer star Thierry Henry. It almost sounds like Terry, but not quite.

Thierry

As Tyler has begun to recede, a number of parents, including the Wayne Gretzkys, have cut straight to the livelier short form. One thing that may be holding the name back is the tarnished legacy of baseball hall of famer Ty Cobb, who gained a reputation for racist and violent behavior.

Also related to the word for wolf, this name has a first syllable that's not appealing to the American ear. Better ic-ending choices: Dominic, Frederic, Eric. 

Ulric

Weston has gone from being a Jane Austenish British surname to a first name with a relaxed American western cowboy feel. Along with other trendy 'n'-ending <a href="https://nameberry.com/boys-names">boys’ names</a>, Weston is rising in popularity, and is now more popular than ever, ranking in the Top 100 since 2021.

Weston also has a glimmer of creative appeal via its connection to the great photographer Edward Weston.
Nicolas Cage chose Weston for his son back in 1990, when it was much more unusual; The Office's Jenna Fischer used it for her baby more recently.

More than 4000 baby boys were named Weston last year, with variations Westin and Westyn also ranking in the US Top 1000. Cousin name Easton is also popular.
