Unisex

Yes, the poet Joyce Kilmer ("Trees") was a man, the very last male named Joyce. And even for women, it's been in limbo for several generations.

Joyce was once a boy name, but took off for girls during the mid-twentieth century, when it spent 1930 to 1947 in the Top 20.

The capital of the United Kingdom makes a solid and attractive twenty-first-century choice, with a lot more substance than Paris. It's in the unisex column, with both girls and boys given the name in recent years.

In the US, London is popular for both sexes, though as the name rises for girls, it's levelled off for boys. Of course, London is far less popular in the UK and other English-speaking countries.

Lou is usually a short form of Louise, Louisa, or Lucy in English-speaking countries, when Lou is used for girls at all. But in France and Germany, it's a fashionable choice all on its own, sure to gain even more widespread style credibility since Heidi Klum and Seal chose it for their daughter.

Lou, all by itself, is become fashionable for girls, which usually makes a name LESS fashionable for boys. But Lou, like Bill or Jim, is rarely used on its own for boys anyway. (You wouldn't name a boy Frederick Lou the way that girls are named Mary Lou or, in the case of Keri Russell's new baby, Willa Lou.) Long form Louis is getting cool again and, with the Lewis spelling, is the Number 2 name in Scotland.

The related Lucas and Luke are both hugely popular boy names in the US and internationally, and now Luca has joined them on boys' popularity lists around the world.

Very much a boy's name in Italy, it's beginning to be seen as a unisex possibility here: actress Jennie Garth used it for her daughter. When spelled Lucca as in the Italian city, it can also be considered one of the place names along with Venezia, Roma, and Milana that make great Italian names for girls.

Reggae master Bob's surname was one of the biggest risers on the popularity charts for girls in 2008, with spellings Marlee and Marely also leaping in favor. Also used for boys, Marley is one of the top unisex names in the US.

Harley is a tough guy, while the rhyming Marley has a softer, gentler image. The name brings to mind reggae great Bob Marley, as well as the lovable dog from bestseller Marley and Me.

Nicky is a forever-cute short form of Nicholas once used as a full name but now relegated to nickname (no pun intended) status.

Make that bird name, and while it does work for both genders, it's far more popular for girls, via Raven Symone.

Bird name Raven, once a symbol of pride for both African-American and Wiccan parents, is finding new life as a superhero name. Raven Darkholme is the real name of Mystique, heroine of the X-Men films played by Jennifer Lawrence. And there is another Raven superheroine in Teen Titans. Some parents may still choose Raven to signal black pride or mystical powers or maybe even Edgar Allan Poe fandom, but we are guessing most inspiration is coming from the comics.

Most female Rays used to spell their names Rae, but now the Ray Charles, ray-of-sunshine way is cool for both genders.

Ray, still and forever, is one of the all-time hippest boys' names, with its jazzy Ray Charles biopic overtones. It's one of the coolest middle names), but works perfectly fine as a first.

Sounded bright and chirpy in the fifties and ranked in the Top 100 until 1980, but by now Robin has lost traction. Robin is, however, having something of a style comeback for boys.

Now that it's no longer fashionable for girls, Robin is rising for boys again. Robin Hood, Robin Williams, Christopher Robin, and Robin the Boy Wonder are all male namesakes, after all. It reentered the US Top 1000 boys names in 2015 for the first time since 1999 and continues to bounce around the lower end of the Top 1000.

Sam has long been used on its own for boys, as accepted standing by itself as it is as a short form of Samuel. Straightforward and down-to-earth, Sam is the name of the son of the co-stars of The Americans, Keri Russell and Matthew Rhys. Sam is one of the most popular names that start with S in the Western world, ranking higher in several European countries than it does in the US, where it's trended downward since the 19th century, though it's always been in the Top 1000.

Sam as a name standing on its own was given to only 18 girls in 2021, versus over 400 boys. But as a short form it's appealing and down-to-earth for both sexes, and heard far more often: There were over 2500 baby girls named Samantha in the US in one recent year and more than 8500 boys named Samuel, so you will hear the name Sam a lot more often than you might guess judging by the numbers for this short form. Like the wildly popular Charlie, Sam is a nickname that works equally well as a girls' name as a boys'. All forms considered, Sam is still one of the most popular names that start with S.
