Guns 'n' Roses musician Axl (born William) Rose created this name by dropping a vowel, a la Barbra Streisand. The traditional Axel is more popular, though celebrity parents Fergie and Josh Duhamel deliberately chose the Axl spelling to honor her rock hero.

Tim is a boyish short form occasionally given on its own. There were 37 baby boys named Tim in the US last year, versus over 1700 named Timothy.

While traditionally pronounced as a homonym for Lee, Glee actress Lea Michele pronounces her name like Leah, and it may also rhyme with Freya. Regardless of your preferred pronunciation, it's interesting to note that Lea has always charted in the US Top 1000, despite coming close to the bottom a few times, making it one of the girl names starting with L that both fits in and stands out.

Streamlined version of the classic boys' names, sometimes a short form of Jonathan, which is in fact an entirely different name from John attached to a different Biblical personage. Jon feels more modern than the traditional John, but some may find it an overly slight variation on an already slim name. Jon Snow is a popular character on HBO's Game of Thrones.

Fiery but slight middle name choice; much more apt to be a redhead's nickname.

Though most Mels are playing pinochle with Murray and Morris, there was a notable Saint Mel. He is one of the earliest Irish saints, a nephew of St. Patrick. He became a priest, then built a great monastery where he served as abbot.

Ron is a masculine name that functions both as a standalone name and as a shortened form of longer names like Ronald, Aaron, or Byron. Ronald, its most common source, derives from the Old Norse 'Rögnvaldr,' meaning 'ruler's advisor' or 'decision maker.'

Taj is a cool-sounding name reflecting the magnificence of the seventeenth-century Indian Taj Mahal, chosen by Aerosmith's Steven Tyler for his son.

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.

Old-time nickname that's following in the fashionable footsteps of cronies Jake and Sam. Abe feels both fresher and cuter -- which is maybe the same thing? -- than those choices right now. You can also get to Abe via Abel, which may prove a friendlier formal name than the gray-bearded Abraham.

Pronounced zheel, it's a dashing conquistador; as gill, it's the nice and slightly boring guy down the street.

Quirky Italian baby name that works for any gender.

An evocative unisex one-syllable name, Poe is most distinguished by its literary reference. Edgar Allan Poe was an influential American author and poet, credited with inventing the genres of detective and science fiction, which might provide inspiration for parents who are fans. And now its choice as the name of the hero played by Oscar Isaac in the new Star Wars movie is sure to catapult it from literary choice to major favorite.

This short-but-strong name is popular for boys in The Netherlands. While Cass is usually a female name in the U.S., it feels just as right for boys.

Avi, the short form of many Hebrew names, is often used on its own in Israel. It entered the US Top 1000 for the first time in 2015.

Just the kind of old-fashioned nickname coming back into style.

Rey, a Ray-soundalike that has ranked on the boys' side for the past 15 years, is about to get more popular for girls too, now that it's the name of the new heroine of the latest Star Wars movie. While the sound of the name is nothing new, the royal connection is, joining names such as Reign (Kardashian) and Charlotte (the new Princess) in an expansive definition of royal baby names.

With the rising popularity of Kai, this more phonetic spelling has been gaining traction as well. Kye debuted in the US Top 1000 in 2015, and was one of the fastest-rising names of the year in 2016.

One of the sweet simple unisex names balanced enough to stand on its own.
