No longer tied to the hapless Ace Ventura, this jaunty, high-flying nickname name is starting to take flight among celebrity and other parents, with its countless positive references to doing well in tests and poker games, on the tennis court and golf course, and in the air.
 Natalie Appleton, Tom Dumont, Jennie Finch, and Jessica Simpson all have little Aces. The best known grownup with the name is Ace Frehley, born Paul, one-time KISS guitarist.

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.

More and more parents are turning to this name as a route to the cool nickname Dax.

Dax is of course most famous as the name of actor and podcaster Dax Shepard, who was named for a character in the Harold Robbins novel The Adventurers. The literary Dax's name was a nickname for Diogenes Alejandro Xenos.

The second syllable -ton, when used in place names, means "town". Dax may refer to the town of Dax in southern France, or it might just be a cool-sounding syllable rhyming with cool boy names Max and Pax and Jax.

Daxton

Inspired by Brandon Lee's character in The Crow and Cuba Gooding Jr.'s in In the Shadows, this name, with its Wiccan feel, was used by a member of Linkin Park. It has ranked in the US Top 1000 since 1995.

Draven

Grayson, which you might think of as a Jason-Mason substitute, has been rising through the US Top 1000 since 1984 and has ranked in the Top 100 since 2011. 

That makes Grayson a modern classic boys' name, with both a sober buttoned-up feel as well as an unconventional masculine vibe. Grayson might plausibly be a banker or an artist, and its resemblance to its female counterpart Grace gives it a feminist gloss.
 
Grayson's biggest problem, if you consider it one, is its persistent, widespread popularity. The Greyson spelling also ranks highly in the US and throughout the English-speaking world, and a wide range of alternative spellings including Gracen, Gracyn, and Greysun have sprung up for baby girls and boys.
 
Last year, about 11,000 baby boys in the US were named Grayson and Greyson alone, as many s were named William or Henry, making it a solidly Top 10 name.

Hudson has risen quickly up the charts over the past 30 years, getting a lot of its style value from New York's Hudson River. That makes it a nature name and a place name that's also got the fashion gloss of New York City.
 The Hudson River was named for 17th century British explorer Henry Hudson, who also gave him name to Canada's Hudson Bay. Hudson has long been a prominent surname. Along with Henry, there was also heartthrob Rock, director Hugh, the musical Hudson brothers, and Kate Hudson today. 
 As a first name, Hudson has been given to several celebrity children, including the sons of Robert Herjavec, Marcia Gay Harden, Gena Lee Nolan, and Drew Lachey.
 Hudson literally means 'son of Hudd', which was a nickname for both Hugh and Richard in the Middle Ages. Streamlined spelling Hud was the name of the macho title character of an iconic Paul Newman film; John Mellencamp has a son named Hud.
 James Barbour pulled a gender switch when he named his daughter Hudson in 2008.
 Along with its popularity in the US, Hudson also ranks in the Top 100 in other English-speaking countries. Its popularity has not, however, extended to other European countries, many of which have laws against using surnames as first names.

Huntley or Hunter

Kashel or Kash

Lander is a name that straddles two trends. It's an er-ending surname name, ala Cooper and Carter. And it's also, more subtly, a green name, in the manner of Fielder or Reed.

Lander

Landon is a popular surname name; it's been dropping slightly in recent years but has surpassed its once more popular rhyming cousin Brandon. For some it may bring back nostalgic memories of Little House on the Prairie 's understanding Pa, played by Michael Landon.
 Landon has been chosen for their sons by two musicians, American Idol finalist Josh Gracin and Blink drummer Travis Barker, whose middle name is Landon. It's also the name of soccer superstar Landon Donovan of the Los Angeles Galaxy.

Landon

An attractive and rare alternative to Luke and Luca. Lucan is the Irish variation.

Lukan

Also spelled Macsen, this ancient name manages to sound modern and cool.  An heroic namesake was Maxen Wledig, a fourth century Spanish-born general who led the Roman army out of Britain, and as Emperor was the most powerful occupant of the throne of the Caesars who had ever ruled Europe from the City of the Seven Hills.

Roman is an ancient name trending in a major way. A surprise hit name of recent years, Roman now ranks in the Top 100 not only in the US but throughout the English-speaking world, and is rising in other European countries as well.
 
Roman owes much of its current popularity to celebrity and pop culture references. It's the name of the youngest son, played by Kieran Culkin, in the TV show Succession. Roman was used for their sons by Cate Blanchett, Debra Messing, and Molly Ringwald.
 Well known Romans include disgraced director Polanski (born Raimund), Polish photographer Vishniac, and onetime star quarterback Gabriel. Francis Ford Coppola has a son named Roman, who is a director now himself.
 Several relatives of Roman are also newly stylish, from Romy to Romilly to Romeo. Definitely a romantic name, however you use it. 
 The French version is Romaine -- and literary parents might appreciate the fact that 'roman' is the French word for novel.

Ryder, one of the current favorite er-ending <a href="https://nameberry.com/boys-names">boys’ names</a>, has been in the spotlight since Kate Hudson and her rocker husband Chris Robinson chose it for their son in 2004. Very popular in several provinces of Canada, Ryder was chosen by John Leguzamo for his son and adorns Boy Meets World star Ryder Strong.
 In the past, Ryder was much more prevalent as a surname, as in American Old Master painter Albert Pinkham Ryder and Brideshead Revisited protagonist Charles Ryder. Not all came by it legitimately, however--Winona Ryder was born Winona Horowitz.
Trivia note: The Ryder Cup is a biennial golf tournament with competing teams from Europe and the US.

Could be an unconventional route to Theo.

Theory

A trendy sounding choice--if we had to give it a meaning would be either "three cities" or "town with trees," but since it's a modern invention, you'd have to pick it for its current feel alone.  Another option: TRENTON, a real place name.
