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.

Alexander has been in a Top 25 boys' name in the US for 30 years now. But namers are still attracted to its imposing historic pedigree.

Xavier originated is use as a given name after Saint Francis Xavier, cofounder of the Jesuit order, who got his name from the Spanish-Basque village where he was born. His birthplace was Javier, the name of which was derived from the Basque place name Etxeberria, meaning "castle" or "new house."

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.

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.

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.

X marks the spot in names these days, usually at the middles or ends of names, but here is one that puts it squarely up front.

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.

This name once seemed a bit grand and pompous for an American baby boy, but a significant number of parents are now preferring it as a substantial platform for the nickname Max, among them Jennifer Lopez and Marc Anthony, who chose it for their twin son.

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.

The jazzy, ultra-cool Dexter, like most names with an "x," has a lot of energy and dynamism.

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.

Eryx has a sci-fi sound and deep roots. In Greek mythology, Eryx was the son of Poseidon and Aphrodite and a king in Sicily. He was a great boxer, but was eventually beaten by Heracles. He probably got his name from Mount Eryx in Sicily, now known as Erice. Never used before 2005, this could be a mythological gem to watch - and an alternative way to honor an Eric.

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.
