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.

Ezra has a lot going for it: the strength of its heroic Biblical legacy, its quirky sound, and its fresh but familiar feel. Ezra is now at its highest point ever, but its intuitive streamlined spelling and deep roots could make it a worth successor to Elijah in the Top 10 -- or even to Liam or Noah at Number 1.

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 spirited Gaelic classic, which became popular in Ireland via the illustrious twelfth century king Rory O'Connor, makes a highly energetic choice, now used for either sex. Rory's gender split is still trending boyward; it's one of the coolest boys' names starting with R.

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.

The poetic, soft-spoken Auden has recently started to be considered as a first name option, used for both sexes, appreciated for its pleasing sound as well as its link to the distinguished modern Anglo-American poet W.H. Auden.

Indigo is one of the most appealing and evocative of the new generation of color names. Color names have joined flower and jewel names -- in a big way -- and Indigo, a deep blue-purple dye from plants native to India, is particularly striking for both girls and boys. Indigo is the name of a character in the Ntozake Shange novel Sassafrass, Cypress & Indigo, and was used for his daughter by Lou Diamond Phillips.

Wallace is so square could almost be ripe for a turnaround, especially with the hipness imparted by the British Claymation series Wallace & Gromit. And Wally makes an adorable Leave it to Beaver retro-style nickname.

Wylie is a friendly, nonchalant rodeo name with an almost irresistible charm; parents may pick up on its pleasant similarity to the more popular, unisex Riley. Although more masculine, we see Wylie as working as well for boys and girls (Richard Anderson used it for his daughter in 1999). Wylie (or the interchangeable Wiley) can also be an original and authentic way to honor an ancestral William. We don't, however, recommend you spell the name the way Corey Parker did: Wylei. Why lay?

A word name with fashionable o-ending that has associations with both the homespun fabric and the mottled cat. Alice Cooper named his daughter Calico decades ago, while it was selected more recently by influencer Paige R Williams for her daughter in 2025.

Carlisle may be a male name in Twilight (he's vampire hero Edward's adoptive father), but in the real baby naming world, it's used about a quarter of the time for girls. Unusual now, we think Carlisle (or Carlyle) has the potential to be the next Carter.

This name of a California desert town, used by Deborah Falconer and Robert Downey, Jr. for their son, makes a much livelier and more individual – not to mention more masculine – improvisation on the themes of India and Indiana.

A masculine way to honor a feminine Page -- although that ett ending is typically found in girls' names.

Sour or sweet? Enough like Lennon, Leonard, and Clement to work, or best left in the fruit basket? That's up to you to decide, but Lemon has been appearing in the US charts for boys since the 1880s.
