Jupiter's partner Juno has entered the mainstream, so it's possible that her divine mate could follow. But not necessarily for boys — Jupiter is currently mostly female in the US, thanks to its similarity to Juniper. Stars including Ed Sheeran and Ashley Tisdale recently welcomed daughters named Jupiter, which could shift the balance even more towards the girls.

In the US, London is popular for both sexes, though as the name has risen for girls, it's levelled off for boys. Currently given to around 200 boys each year, it is nearly five times more popular for girls, however, it been on decline across the board since its peak in 2013. Conjuring up images of Big Ben, red phone boxes, and the London Eye for some, but perhaps the rush hour commute and grey skies for others, London is far less popular in the UK and other English-speaking countries.

Despite its distinguished pedigree and popularity in Israel, Disney's Little Mermaid cartoonized Ariel in the US, at least in some people's minds. But it was used for a male character in Shakespeare's The Tempest centuries ago.

Peyton is the most-used spelling of this popular name, thanks to football star Peyton Manning. It rose to fame in the 90s and was solidly - or statistically - unisex in the early 2000s, however, the 2010s saw it shift to a more feminine leaning option. Nevertheless, with its surname-style and gentle sounds, Peyton could still fit in with the likes of Grayson, Everett, and Cameron.

The girls have Violet and Scarlet and Ruby and Rose, but for the boys there's a much more limited palette of color names. Gray (or Grey), is one exception, which could make for a soft and evocative--if slightly somber-- choice, especially in the middle. Kaitlin Olson and Rob McElhenney recently named their son Leo Grey.

St. Landry was a seventh century bishop of Paris, founder of the city's first hospital, though in the US, it may be better connected with legendary Dallas Cowboys coach Tom Landry, an association that makes this a sports hero name with a hint of ruggedness. Familiar in France between the 1970s and 2000s, it also featured at the latter end of the US Top 1000 during the 20210s.

Though Genesis is a Top 100 girls' name in the US, it's by all rights a unisex choice.

Bentley, a somewhat stuffy British surname, previously associated primarily with an incredibly expensive English car, has had a recent surge in popularity, thanks largely to the reality TV shows 16 and Pregnant and Teen Mom, with Bentley being the name of the son of breakout star Maci (another new favorite) Bookout.

Windswept and dramatic, but perhaps asking for trouble. Quite popular in Denmark and Sweden, where it derives from Stromr, which is a fairly common surname. Storm Thorgerson is a famous bearer of the name - he designed iconic album covers for Led Zeppelin, Black Sabbath, the Cranberries, Anthrax, and Pink Floyd.

Creative name whose only limitation is that it looks like it would be pronounced akin to Alicia and Elissa — although as a Biblical boys’ name, it is traditionally pronounced ee-LIE-shah.

A sweet and sophisticated nickname which feels fresh again after many years in style limbo. For literature lovers, it brings to mind Theodore "Laurie" Laurence from Louisa May Alcott's Little Women. Another famous bearer is English actor Hugh Laurie.

Even less subtle than Duke or Earl, this name shot up the popularity charts in 2013, the same year young Prince George was born and the craze for all things royal (and Royal) began. Today, it's a leading boys' name on Nameberry's own popularity charts.

Juniper is a nature name that we really like. While it's trendiest for girls -- about 2500 baby girls were named Juniper in 2022 versus 34 baby boys -- the most notable Juniper in history was the saint Brother Juniper, a follower of Saint Francis renowned for his generosity. Blessed Junipero Serra, who founded the first of the California Missions, took his name from the earlier Saint Juniper.

Botanical choice that can work for either gender. Simple and straightforward. Caveats: rue means "regret" in English, and "street" in French. Now in the Top 1000 in England and Wales for girls and trending upwards in the US, it is nevertheless still given to a handful of boys each year. It could equally work as a nickname for a Ruben, Rudy, or a Rupert.
