Fairly popular a hundred years ago but out of the US charts since 1978, the quirky yet edgy Roscoe feels very much in step with the trending o-ending boy names popular now, such as Milo, Hugo, and Otto. A Top 1000 choice in the UK (albeit near the latter end), it could make a cool alternative to Ross, Russell, Robert, and Ronan.

Atticus, with its trendy Roman feel combined with the upstanding, noble image of Atticus Finch in To Kill a Mockingbird, is a real winner among boy names. Atticus entered the US Top 1000 in 2004 and is a firm Nameberry favorite.

One of the most romantic of appellations, Caspian is a geographical name referring to the large salty sea between Asia and Europe. It's also the name of the hero of C.S. Lewis's beloved Chronicles of Narnia, Prince Caspian.

Cyrus is one of those surprising names that have always ranked among the Top 1000 boy names in the US. On an upward trend since the mid-90s, Cyrus now sits in that comfortable place between too popular and too unusual.

Actor Kit Harington, aka the dreamy Jon Snow on Game of Thrones, has given this nickname-name new style and appeal for boys. Actress Jodie Foster used it for her son back in the 2000s, while actor Kit Connor of Heartstopper fame may have introduced it to a wider audience.

This ancient name, also spelled Caspar, is finally shedding its ghostly image and moving into the 21st century. Popular in the Netherlands and Scandinavia, where it's sometimes shortened to Cas, Casper could ride the style coattails of cousin Jasper.

A short but strong biblical name with multicultural appeal, Asa is enjoying new visibility thanks to hot young actor Asa Butterfield of Hugo fame.

Rugged, outdoorsy, and full of energy, Wilder entered the US Top 1000 back in 2015. Part bad boy, part Western, part preppy, and part nature-loving, Wilder is given to nearly 800 babies each year.

Evander is a name that could build on the popularity of shorter form Evan, and could work and play well with schoolmates like Zander and Xander.

With a touch of celestial power, a hint of clunky charm, and the totally cool -o ending, Cosmo may well be finally shaking itself free of both the Seinfeld association (which made it a punchline of a joke) and the cartoon fairy association from The Fairly OddParents. In fact, it is in the Top 1000 in the UK and a favorite on Nameberry.

Gideon is a no-longer neglected Old Testament name, but still makes an excellent choice for parents looking to move beyond such overused biblicals as Benjamin and Jacob. In the Old Testament, Gideon was a judge called on by God to rescue the Jews from the Midianites, and the name was popular among the Puritans.

Rugged and outdoorsy, Heath was an obscure choice until the 1960s when it was used in the television series, The Big Valley for character Heath Barkley. It peaked in the 70s when it reached the US Top 200, but it has since fallen to the latter end of the Top 1000.

Walker is both a Waspy surname name—as in the W in George W. Bush—but it also has a gentle ambling quality and a creative connection to such greats as writer Walker Percy and photographer Walker Evans, whose father was also named Walker.

Chosen for their daughter by Bruce and Demi (inspired by the To Kill a Mockingbirdcharacter), and for her son by Tai Babilonia, an interesting choice for either sex, with overtones of a "good scout" and the upstanding qualities of a Boy/Girl Scout.

This is a name we've seen the potential of for some time now — A Greek island and a prestigious scholarship make for a preppy first name with the uber-stylish S ending. Needless to say we were not surprised that Rhodes cracked the Top 1000 in 2022, and we expect it to keep rising. Rhodes was recently chosen by actress Emma Roberts for her son, born in 2020.

Sonny is one of the generic boy nickname names making a surprise reappearance, and it was recently used by actor Jason Lee. Another surprise: It's been on the US Top 1000 list every year since 1927, and as of 2023, it entered the Top 400 for the first time. Laidback Sonny is also popular in the UK, New Zealand and Australia.

Shepherd is an occupational surname with a pleasant pastoral feel. It was chosen for their son by the Jerry Seinfelds, which might inspire others to follow their lead.

Jaunty and raffish, Rafferty is one of the most engaging of the Irish surnames, used by Jude Law and Sadie Frost for their son. Fortunately, it doesn't still go by its original form: O'Raighbheartaigh.

With mythological names rising, the handsome son of Zeus and god of medicine, music, and poetry among many other things might offer an interesting, and melodic option. Similar in style to Atlas and Atticus and similar in sound to Arlo, Paolo, Paul, and Ollie, Apollo entered the US Top 1000 back in 2012, and was propelled upwards after it was chosen by Gwen Stefani and Gavin Rossdale in 2014.

Wells is a newly-famous baby name thanks to pregnancy guru Rosie Pope, who uses it as the short form of the buttoned-up Wellington, name of her youngest child.
