all possibilities

A popular name in Denmark, in this country Bo has some cowboy swagger and a lot of substance in its minimal two letters. In Mandarin Chinese, Bo means "wave".

Baseball commissioner Bowie Kuhn put this name in play as a first name, but David Bowie (born with the considerably less marketable moniker of David Robert Jones) dyed it blond and gave it charisma. He changed his surname in 1965 to avoid confusion with the then popular Davy Jones of The Monkees, and especially since his death, his admirers have seen it as an increasingly viable baby name namesake.

While the variation Carmine is more familiar for boys, Carmen has also been used as a masculine name; consider the very macho Carmen Basilio — the American boxer famous for defeating the great Sugar Ray Robinson — or composer Carmen Dragon.

Drew, which projects a polished, somewhat intellectual impression, is rapidly becoming the Andrew nickname of choice, replacing the past favorite, Andy. It is fully capable of standing on its own, which it has for many decades, non-stop since 1942.

Ellis is a former Old Man Name turned gender-neutral choice for the 21st century. It's one of the less used names in the currently popular El-family.

Finley has been used for both sexes for enough years to become one of the most popular unisex names. Given nearly equally to boys and girls, Finley appeals to contemporary parents as a truly gender neutral choice.

Frankie is used in almost equal numbers for girls and boys these days. Fun fact: in 2015, it ranked Number 992 for both genders in the US. It is a highly popular boys' name in England and Wales.

Jagger is a swaggering Rolling Stone of a name that's been picked up by a number of fellow celebs, including Lindsay Davenport and Brett Scallions--while Soleil Moon Frye pulled a gender switch when she bestowed it on her daughter. It's edgy with a touch of danger.

James is one of the classic Anglo-Saxon names, a stalwart through the ages that is more popular—and yes, stylish—than ever today. It recently came out Number 1 in a poll of America's favorite boys' baby names, and is the most common male name, counting people of all ages, in the US.

King David's father turned 1980s cowboy, Jesse is now down in popularity. The name is associated with a wide variety of bearers, from outlaw Jesse James to Olympic athlete Jesse Owens to activist Jesse Jackson to current actors Jesse Tyler Ferguson and Jesse Eisenberg. The spelling Jesse is more usual as a boys' name while Jessie is more traditional for girls.

Journey is one of the hot new spiritual names. Although Journey was given in 2015 to over 1100 baby girls and fewer than 100 baby boys, it's more visible on the celebrity baby scene as a boys' name: Megan Fox and Brian Austin Green just chose the name for their third son, who also has the unisex middle name River.

Though Jules hasn't been on the US popularity list in fifty years, it is a current hit in its native France—where it's currently in the Top 10—and we can definitely see it making a comeback here, being far more romantic than, say, Jim.

Attractive British place-name with a sense of humor. Fun fact: John Wayne played five characters with the first or second name of Kirby.

Knight (as opposed to Night) is a name clad in shiny armor. This high-ranking word name was introduced by singers Kelis and Nas. Knight might join brothers King, Royal, and Noble in a new definition of royal baby names.

Many European cultures spell Christopher with a K and thus the short form Kris. There were about 35 baby boys named Kris, just Kris, in the US last year, and only a handful of baby girls -- this after the name ranking in the Top 1000 for both genders from the late 1940s through the 1970s. However you spell it, it's an appealing name that's in a slump right now because of overexposure. It's also one of the original gender neutral names, paving the way for a new way of thinking about names and gender.

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.

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.

Morgan, once split evenly between the sexes, is a strong and attractive Welsh favorite, still a common boys’ name in Wales. Morgan is now more often a girls' name in the U.S. – about 2000 girls were given the name in one recent year, vs. 362 boys – though it's one of the most traditional unisex choices. Morgan was actually a Top 200 pick for boys in Victorian Britain!

Noah is nearly a patriarch of popular baby names at this point, going from Old Testament graybeard to Top 10 name in 2009, hitting Number 1 in 2013, and now settled into second place in the US for five years.
