A variation on the popular Colton, Colter has been climbing up the US charts since 2010. Given to around 1000 boys each year, it is now in the Top 500, and ticks the boxes for being a cool occupational name with rugged, Wild West vibes, and for giving the familiar nickname Col, or the alternative, Colt.

The presidential Tyler rocketed up popularity charts in the late 1980s and early 1990s (it ranked Number 9 for that entire decade), along with cousin Taylor, becoming almost pandemic across the land-- and to make matters more confusing, both (especially Taylor) have been used for girls as well.

The jazzy, ultra-cool Dexter, like most names with an "x," has a lot of energy and dynamism.

Cassander is the masculine form of Cassandra, and the name of an ancient king of Macedon from the 3rd century BC. It could make a nice alternative to Alexander or a refreshing way to honour a female relative named Cassie/Cassandra/Sandra.

The name of the Aster flower, named by the English, was derived from the Greek word for star. Like many floral names, Aster is much more popular among baby girls.

The name of this pretty Mediterranean shrub is reminiscent of popular classic Oliver, and interestingly its etymology appears to overlap too: oleander most likely derives from Greek rhododendron "rose tree", with its form successively influenced by laurea "laurel" and olea "olive tree".

On the rise as an independent name: Zander and Xander are both widely used can increasingly be found as characters in movies and on TV.

The surname-style Alden has been on the rise in the US in recent years, while tree-inspired Rowan is a top choice. Combine this with the popularity of names ending in -er such as Carter and Parker and it makes sense why Alder is now 4 times as popular as it was a decade ago. Given to 125 boys in a recent year, it could be a modern way to honor an "Al".

While this is usually thought of as a girls' name because of the Bond Girl connection, its sound is masculine and there's no reason it couldn't work for boys.

This shimmery Age of Aquarius unisex flower child name is making a comeback, along with metal and gem names like Steel, Jade, and Ruby.

One of the hot two-syllable T names of the nineties (along with Tyler, Trevor, and Taylor), and well represented on soap operas; Tanner is still widely used, but its popularity is declining.

Ryder, one of the current favorite er-ending boys’ names, has been in the spotlight since Kate Hudson and her rocker husband Chris Robinson chose it for their son in 2004. Very popular in several provinces of Canada, Ryder was chosen by John Leguzamo for his son and adorns Boy Meets World star Ryder Strong.

Piper's rising popularity for girls makes it an unlikely masculine choice.

Booker would make for a very cool name, for writers, reformers, R & B fans and those wanting to pay tribute to Booker T. Washington.

Thanks to Elmer Fudd, Elmer the Cow, Elmer the elephant, Elmer's glue and the similar Elmo, this name might, to some feel like a jokey choice: the quintessential so-far-out-it-will-always-be-out name. And yet, the US statistics don't quite support that perception.

European royal name, and to Americans a place-name evoking the majestic mountain in Washington state.

The kind of nouveau macho name favored by NRA-leaning parents, Gunner could appeal to those who like other more military or gun inspired names, such as Hunter, Remington, and Cannon. It got a boost up the charts in 2009 when The Killers' frontman Brandon Flowers gave it to his son.

An x makes any name cooler, so that Baxter has a bit more pizzazz than the original Baker. Baxter had some currency as a first name a century ago--it was on the popularity lists sporadically from 1880 till the 1920s, peaking at Number 515 in 1886-- which means it's just about due for a comeback. And we can see Bax as a worthy follow-up to Max and Jax.
