Atlas is one of those names that was previously thought too powerful for a baby boy, who would have to be strong enough to carry the world on his shoulders. Now Atlas has joined the pantheon of Greek and Roman god and goddess names in the realm of possibility, along with Mars, Zeus and Apollo.

A classic in its native Scandinavia, Axel has a cool rock 'n' roll flavor in the US, thanks to Guns N' Roses' Axl Rose (born William). With its distinctive letter 'x', it has an effortlessly cool vibe about it, and is currently growing in popularity.

The name of a graceful tree in the poplar family with heart-shaped leaves so delicate they quiver in the gentlest breeze, Aspen is also the name of a trendy Colorado ski resort. Aspen started as a unisex name possibility but now is much more frequently worn by girls.

Also spelled as Kalliope — the more traditional Greek transliteration — Calliope means "beautiful voice", making this a musical and poetic choice. It was rarely heard in the US until the 2000s when Calliope "Callie" Torres from the show Grey's Anatomy helped introduce it to a wider audience.

Corbin, the name of the castle where the Holy Grail was said to be hidden, came to the fore in the 1980s via actor Corbin Bernsen when he was the high profile star of LA Law, but its use is only now escalating as part of the mania for two-syllable names starting with c or k, as well as from the more youthful image of Corbin Bleu, the attractive actor-model-dancer-singer who was one of the stars of the Disney hit High School Musical.
