Amias or Amyas is a <a href="https://nameberry.com/list/317/unique-baby-names">unique name</a> with an attractive sound and feel and a lovely meaning. Though it might sound like a Biblical name, it is not, but is a surname that may be related to Amadeus or even be a male version of Amy--which would make it one of the few boys' names to be derived from a girls'.
 The Amyas version became known via the hero of the mega-popular 1855 Charles Kingsley novel, Westward Ho!, Captain Sir Amyas Leigh.

With mythological names rising, the handsome son of Zeus and god of medicine, music, and poetry among many other things might offer an interesting, if high-pressure, option. 
 
But if Romeo and Venus are now deemed baby-appropriate, why not Apollo? Olympic speed skater Apolo Anton Ohno might inspire some parents. And now that it's been chosen by Gwen Stefani and Gavin Rossdale, it could take off as their first son's name—Kingston—has.
 Other cool associations include NASA's Apollo program, from 1961-72, that succeeded in putting the first humans on the moon when astronauts Neil Armstrong and Buzz Aldrin landed their lunar module and walked on the moon's surface. There's also the historic Apollo Theatre in Harlem, on whose stage the careers of Billie Holiday, Ella Fitzgerald, Artetha Franklin, Stevie Wonder, the Supremes, the Jackson 5, and countless others were launched.

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.

 Atlas was one of the fast-rising names on the list in recent years in the USA, jumping from oblivion in 2012 into the Top 500 in 2015, and climbing several hundred places higher since then. Anne Heche was one of the first to make this audacious choice, but several celebrity parents have followed suit.

 As well as the mythological connection, Atlas is a cool geographical word name – perfect for the child of parents who love traveling or who hail from different parts of the globe.

With Azariah and Azriel in the Top 1000, and Ezra, Josiah, and Isaiah in the Top 100, it makes sense that this lesser known Hebrew choice is being quietly revived in the US. Most likely deriving from Uzziah or Azaziah, Azaiah was given to around 170 babies in 2023.

Azaiah

This traditional Arabic name, found throughout several other Middle Eastern and African languages and cultures, is one of the 99 names of Allah.

Cairo is an exciting place name possibility with upbeat o ending and an on-trend first syllable. Debuting in the US Top 1000 in 2015, it has been climbing ever since, and, as of 2023, it is given to more than 1000 babies each year. 

The name derives from the Arabic al-Qāhirah, the name given to the Egyptian city in 969 AD by the Fatimid dynasty. With the meanings "conqueror" or "vanquisher", it was named to celebrate the strength of the dynasty. Today, Cairo is a busy city, a site of historical importance, with ancient buildings and museums but also contemporary architecture and film festivals.
 
As a given name, Cairo owes its sudden popularity to its choice by rapper Tyga for his son King Cairo's middle name. And Brazilian place kicker Cairo Santos helped popularize the name when he joined the Chicago Bears football team. Santos is named for his father, also Cairo.

Another influence propelling Cairo up the ladder: the popularity of the name Kai. And Cai could certainly be a nickname for Cairo.
 
Trending upwards in the UK and continuing to climb in the US, Cairo has also been joined in the charts by spelling variations, Kairo and Kyro, and is also given to nearly 50 girls each year. When you combine all these Cairos together, it was given to nearly 3000 babies in a recent year, making it feel like a name around the #120 mark, similar in popularity to Jasper, Emmett, or Milo.

Calix is once-obscure name that is starting to see some use in the US, where 47 baby boys were named Calix in 2023. An indirect influence is the actress Calista Flockhart, who introduced Americans to the female version of this attractive Greek name to prominence.
 
Calix derives from the Latin word for chalice, calyx, which in turn came from the Ancient Greek word kálux, meaning "husk" or "pod." It is also considered a diminutive of Calixtus, a variation of the Late Roman name Callistus meaning "most beautiful." Calyx can also be spelled Calyx, as in the funnel or chalice-shaped part of a flower.

Many may associate Mario with the popular platform game - unsurprising when it's the 5th best-selling video game worldwide, and was voted the 2nd best game ever by IGN in 2024. The titular plumber was apparently named after American businessman, Mario Segale, who rented a warehouse to Nintendo, and this in itself reflects that Mario is much more established than just a name for a video game character. 
 
Mario is one of the many surprising names for boys that has always ranked among the US Top 1000, in the top half of the list for more than a hundred years. While it may now be in decline, it is still given to around 800 boys each year, and its similarity to popular Mateo stops it from feeling too dated. 
 
Derived from the Roman name Marius, Mario can have a number of different meanings. On one hand, it might be considered a mythological name, thanks to its origins in Mars, the name of the Roman god of war and of the so-called red planet. Alternatively, it could come from the Latin roots mas or maris meaning "male", or from the Latin word mare meaning "sea". 
 
Popular in Spain, Portugal, and Italy, Mario has a number of notable namesakes. These include singer and actor Mario Lanza, racing car driver Mario Andretti, and author of The Godfather Mario Puzo.
