Friendly but substantial.

Extremely popular in Wales, where it began as a nickname for someone with fair hair or a fair face, this bright and simple name is a winner by its very nature. Can also be spelled Wynn, Winn or the very literal Win.

Cameron is still more popular as a boy's name than a girls and this simple, snappy short form works well for either sex.

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.

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.

Sky is an ambigender nature name that was first legitimized as the character of Sky Masterson in the 1950 musical Guys and Dolls, played in the film version by Marlon Brando. It's a name we appreciate for its clear, wide-open feel, less hippyish than others like Rainbow and Starlight, and makes an appealing middle name possibility.

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.'

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

This zippy short form of Zachary is more and more often standing on its own -- sometimes as Zac, Zach, Zack, or even Zakk -- but this simple-yet-straightforward version may be the very best.

The sidekick in almost every movie or TV show with an Italo-American setting, this once common name has now fallen onto the endangered list, given to fewer than 50 baby boys each year.

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.

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.

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

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.

Ike, once the quirky one-person nickname of President Dwight Eisenhower, has morphed into a cool kid nickname of the early 21st century.

Short form of Alfred that had fallen out of favor, but could come back alongside Alfie and other clunky old-style nicknames like Gus and Ike.

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.
