Felix is one of those ancient but nontraditional names for boys that have come into favor over the past few decades, a favorite of parents who want a masculine name with history and heft that breaks ranks with the standard Franks and Freds. Felix is also an international darling, ranking in the Top 100 in several European and English-speaking countries.

Max was derived from Maximilian, a Latin name that originated from the Roman family name Maximus. The character name Max in the children's classic Where the Wild Things Are had an impact on baby namers. Max is a widely used name internationally.

Lennox is an aristocratic and powerful Scottish surname name made truly special by that final x. The worldwide fame of British boxer--World and Olympic champion--Lennox Claudius Lewis brought the name into the spotlight as a first name, while as a last it's tied to Eurythmics singer Annie L.

Beatrix has a solid history of its own apart from Beatrice, with that final x adding a playful, animated note to the name's imposing history and stately vibe.

Now that many dogs are named Max, it's safe to use this sleek, solid, regal name again for your child. And with the charm of its final x, its regal meaning, and its offbeat simplicity, Rex is definitely one to consider.

Maddox, a previously obscure Welsh family name with a powerfully masculine image, suddenly came into the spotlight when Angelina Jolie chose it for her son in 2003. By the following year it was in the middle of the Top 1000, and it has risen since.

Knox is an old Scottish surname that Brad Pitt (whose great-great-grandfather was named Hal Knox Hillhouse) and Angelina Jolie took out of the back cupboard, dusted off, and elevated to coolness--to the point where it entered the popular baby names list in 2009. Knox now ranks among the most influential celebrity baby names.

In Greek mythology, Nyx was a powerful goddess and the embodiment of the night, giving this name a dark yet mystical feel. While some may associate too strongly with the word nix (meaning "nothing", "refuse" or "put an end to"), or to the make-up brand Nyx, it was nevertheless chosen for 64 girls (and 26 boys) in the US in a recent year.

Phoenix is a New Age name symbolizing rebirth and immortality. It's also a place name, a color name, a mythological name, AND an animal name, combining several of today's hottest trends in one appealing package.

Calix is once-obscure name that is starting to see some use in the US, where 62 baby boys were named Calix in 2024. An indirect influence is the actress Calista Flockhart, who introduced Americans to the female version of this attractive Greek name to prominence.

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.

The appealingly energetic Dax, with its trendy X-ending, re-entered the Top 1000 in 2007. Its somewhat sci-fi vibe emanates from his appearance as a fictional being in the Star Trek universe, seen on the TV show "Star Trek: Deep Space Nine." The Power Rangers character Dax Lo was the Blue Ranger.

The independent Alex has become a classic in its own right. One of the truest unisex names, Alex is used almost equally for both sexes. Alex is used both on its own and as a short form of formal names of both genders, such as Alexander, Alexandra, and Alexis.

Jinx, a James Bond heroine name has an ominous meaning but kinetic energy. In the film "Die Another Day," the actual first name of the character played by Halle Berry is Giacinta. It could therefore be a playful nickname to Ginevra, Jessica, Genevieve, Gianna, Josephine, or Georgina, or a bold choice for those wanting some sparky and witchy.

Ajax is the name of two Greek heroes, both who fought in the Trojan war and feature in Homer's "Iliad". Distinctive yet familiar in sound, thanks to similar choices like Jack, Asa, and Ajay, Ajax is also the name of a foaming cleanser in the US, and if you find that reference too strong, you might try the shortened Jax instead.

With its cool -X ending, Jax is an update on the classic nickname Jack, likely inspired by the rise of Jackson. It garnered attention in the US thanks to the game, Mortal Kombat II back in the '90s, and was pushed up the charts when it was used in the show Sons of Anarchy, in which Jackson "Jax" Teller is the central character.

This name of a character played by Kirsten Dunst in the movie Virgin Suicides, originally a novel by Jeffrey Eugenides, is gaining attention, also thanks to the heroine Lux, Lady of Luminosity in the League of Legends games. Luz is the Spanish version.

Fox is one animal name backed by a longish tradition, and then popularized via the lead character Fox Mulder on X Files. Fox is simple, sleek, and a little bit wild, and could make an interesting middle name.

Swashbuckling name worthy of a hero in a romance novel. Deveraux or Devereaux is drawn from the town of Evreux in France and combined with the prefix de- denoting it likely referred to a noble of that area.

Hendrix is one of those hip rock and roll names, like Lennon, Jagger and Presley, that have been used by fellow celebs and others, to honor the seminal guitarist/singer/songwriter Jimi. And this one has the trendy 'x' ending, as well, helping to propel it up the charts and into the spotlight.
