Quirky cool Arlo is now well and truly back. Last year it broke into the US Top 200 boy names and consistently ranks among the most popular boy names on Nameberry. Along with its Irish and English roots, Arlo may be a shortened form of the Italian Carlo or the Spanish Carlos, both forms of Charles,and in Basque-speaking regions it is the word for area.

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.

Milo is most commonly considered to be Germanic name derived from the Latin word miles, meaning "soldier." However, there is evidence to suggest it also may have independently spawned from the Slavic root milu, meaning "merciful." Milo predates brother name Miles, a variation that evolved when the name immigrated to the British Isles in the Middle Ages. Mylo is an alternate spelling.

Hugo, the Latin form of Hugh, has more heft and energy than the original -- and of course we love names that end (or begin, for that matter) with an o. This one is especially appealing because it's backed up by lots of solid history and European style.

Ari, the short form of Ariel (or any other Ari- beginning name, such as Aristotle) stands up better as a boys’ name than its progenitor does. It is also short for Aristotle, as in Onassis, and is a prominent character on TV's Entourage -- the uberagent Ari Gold.

Nico is one of the great nickname names, full of charm, energy and effortless cool -- a neo Nick.

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.

Beau suggests someone devilishly handsome, with a large measure of southern charm—a nice image to bestow on your boy. Often solely a nickname in the past, it's now standing firmly on its own. Beau has been on the Social Security list non-stop since 1969.

Harvey, which was brought to England by the Normans, is a genial, old-timey name that has been much more popular across the pond in the UK. It was a Top 100 choice in England & Wales from 1997 until 2021, though 2022 saw it fall just slightly.

Cillian is one of the native Irish names that, along with Aiden and Declan, is becoming an unlikely favorite in contemporary America. The Killian spelling has been more popular in the US, but Cillian's star is rising, perhaps thanks to Irish actor Cillian Murphy, star of Oppenheimer and Peaky Blinders.

Succinct and sharp, Ira is one of the shortest Old Testament names, belonging to one of King David's thirty 'mighty warriors.' It was widely used in the US from the 1880s to the early 1930s (it was Number 57 on the Social Security list in 1881), but fell off completely in 1993, only to return in 2016. Currently, it is in the latter half of the US Top 1000, given to around 260 boys each year.

Rufus is a rumpled, redheaded (it was the nickname for red-haired King William) ancient Roman name popular with saints and singers (e.g. Rufus Wainwright); now, Rufus is on the cutting edge of cool.

Patrician to the core, Hugh was firmly in the Top 100 until 1903. It's never achieved those heights again, though it has always managed to remain in the Top 1000, scraping bottom at literally Number 1000 in 2006 before reversing course and heading back upwards.

Jaunty and dapper, Rafferty is one of the most engaging of the Irish surnames, used by Jude Law and Sadie Frost for their son in 1996.

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.

Jonas has a slightly more grandfatherly image than the English version of his name, but that only adds to its retro appeal. And though it may lag behind Jonah in this country, Jonas is riding a huge wave of popularity in Europe, where it ranks highly in Germany, Switzerland, Austria and Norway.

Friendly and rugged at the same time, Anders is a Scandinavian form of the Andrew and Andreas family, used across Norway, Denmark, Sweden, and in the US. Consistently in the American Top 1000 since 2010, a recent year saw it given to around 300 boys.
