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.

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.

Clunky yet cuddly, Wilbur is a stylish name in the UK where it currently sits in the Top 600, as cool as Rupert or Wilfred. Its merits are starting to be rediscovered in the US, where it was last truly popular more than a century ago. A recent year saw it given to 42 boys.

Otto is cool again. Long a quintessential Old Man Name, Otto has been promoted to trending darling of adventurous baby namers.

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.

Quinn is an engaging Celtic surname, zippy, concise and strong. While it may now lean feminine in the US, given to girls about 80% of the time, it is still given to a substantial number of boys: 615 in a recent count.

Ernest is one of those sober, so-far-out-they're-beginning-to-be-reconsidered Great Uncle names. Ernest recently received a big style boost when Britain's Princess Eugenie chose it for her second son.

In Celtic lore, Fergus was the ideal of manly courage, making it a charming, slightly quirky Scottish and Irish favorite.

Popular in Croatia, Spain, New Zealand, and Slovenia, Niko has also been rising up the US popularity charts for boys since the late 2000s. Fresher than Nicholas, spikier than Nico, it currently ranks just outside the US Top 300.

Orlando, the ornate Italianate twist on the dated Roland, with a literary heritage stretching back to Shakespeare and before, has appealing book-ended o's, and is open to combination with almost any last name, a la British actor, Orlando Bloom.

A name with plenty of grandeur, but a playful nickname, Wolfgang blends sophistication, wildness, and gothic imagery. While it may feel surprising in this century, it does have an allure for those who want a name associated with dark academia, Halloween, history, intellect, wolves, and art.

Emmerson is a masculine name of Germanic origin meaning 'son of Emery' or 'brave and powerful.' Originally a surname derived from the medieval given name Emery (from Germanic elements 'amal' meaning 'work' and 'ric' meaning 'power'), it transitioned to first name use following the surname-as-firstname trend. The name gained moderate popularity in English-speaking countries in the late 20th and early 21st centuries, appealing to parents seeking strong traditional names with contemporary style. The spelling variation Emerson connects to American philosopher Ralph Waldo Emerson, adding intellectual and literary associations. While traditionally masculine, Emmerson has seen some use for girls, particularly with the nickname Emmy. The double 'm' spelling distinguishes it slightly from the more common Emerson variant.
