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.

With a long and noble history -- Cyprian was one of the great Christian Latin writers -- this could make a highly unusual but meaningful choice.

Tiernan is the slightly edgier and sharper cousin of Kiernan. This is one Irish surname that is attractive but distinctive; Tierney is another, related, option.

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

Country singer Travis Tritt is partial to the letter T for his children's names: he has a Tyler, a Tristan, and a son named Tarian. Tarian is a unisex Welsh name which, though used more for girls in Wales, would be perfectly acceptable here for a boy.

Rakish nickname able to stand on its own.

Penrose – an ancient locational surname derived from several villages in Cornwall, Wales, and the Welsh border country of England – might work as a first name, although the "Rose" syllable might lead the uninitiated to assume it's a female name. As a middle name, however, it would make for a surprising and distinguished choice. A male Penrose could be called Pen/Penn, Ross or Roe for short.

Bix is a cool and jazzy nickname name, thanks to that final x. It's largely associated with the legendary and influential cornet player (and inspiration for the novel Young Man With a Horn), Bix Beiderbecke. He was born Leon Bismark Beiderbecke and his nickname derived from his middle name.

Pax, one of the variations of names meaning peace that are newly popular in these less-than-peaceful times, got a lot of publicity when chosen by Brad & Angelina for their Vietnamese-born son. Parents attracted to Pax may also want to consider Paz, the unisex Spanish version, or Paxton, a growing-in-popularity surname choice that shares that magical X-factor.

Mostly feminine, though "Office" star Rainn Wilson gives it a slight masculine twist. You might also use this as a short form of Raines.

Rainer is one of those baby names that is still under-the-radar but has been quietly gaining traction: The number of boys who've received the name has doubled in the past decade, to just under 50. Part nature name and part traditional German name for boys, Rainer can claim a place among the two-syllable r-ending baby names so fashionable for boys today.

While some may think of ruby slippers and a yellow brick road, Oz is a legitimate Hebrew name denoting power. An element in a number of names including Ozni, Oziel, and Ozias, it may also be used as a stand-alone choice which may appeal to those who enjoy the likes of Ty, Ed, Bo, and Cy.
