Rock Climbers' Names

Adam -- a primal Old Testament name -- was revived as a 1960s cowboy name. Adam is not as popular as it once was and feels ready for a respite, replaced by newer A names like Aidan/Aiden, Avery and Axel. Its most prominent current bearers include Adams Sandler, Levine, Brody and Driver -- who plays a character named Adam on Girls.

This a-ending feminine form of Adrian, from the northern Italian city of Adria, is a soft and lovely Italian choice. It appears as a character in Shakespeare's The Comedy of Errors.

The independent Alex has become a classic in its own right. One of the truest unisex names, Alex is used almost equally for both sexes. Alex is used both on its own and as a short form of formal names of both genders, such as Alexander, Alexandra, and Alexis.

Cute nickname of Angela and other angelic names, Angie is now being used on its own, although its popularity has fallen in recent years. That said, Angie is one of those surprising classics, hanging on in the girls' Top 1000 continuously since its inception in 1880.

One of the more widely used combination forms.

Brooke has long projected an aura of sleek sophistication, and can also be seen as a stylish water name.

Chelsea is still being used, but it was much more popular a few decades ago--it peaked at Number 15 in 1992. Chelsea first entered the American consciousness in a major way via the character Jane Fonda played in On Golden Pond in 1981 and later of course was frequently in the headlines when Chelsea Clinton (whose name was inspired by the lyric of a the Joni-Mitchell-Judy Collins song "Chelsea Morning") became First Daughter.

Chris is a long-running nickname used almost equally for boys and girls. While past its prime, Chris stands out as sounding completely appropriate for both sexes, perhaps because of its widespread use as a short form of both the popular Christopher and Christine. Chris manages to retain its crisp appeal even though its fashion moment is over.

Daniel is one of only a handful of male names that sounds both classic and modern, strong yet approachable, and popular but not cliched. It also has a solid Old Testament pedigree. The only real downside: There are about 10,000 Daniels named each year, making it a less than distinctive choice.

David is an enduring worldwide classic, used from ancient times to the present day.

Delaney has been a popular Irish surname name for a couple of decades, projecting buoyant enthusiasm plus a feminine feel.

Commonly used in Russia, has an Old World Slavic feel. The original Galen can be used for girls as well as boys.

Isabelle is the French variation of Isabel, which emerged in the Middle ages as an Occitan form of Elizabeth. Medieval queens Isabella of Angoulême and Isabella of France helped popularize the name in the United Kingdom. Isobel is the Scottish version, Isabella the Italian, and Izabel is used in Brazil.

Attractive and equally intriguing alternative to Katya.

Molly is one of the original nickname names, ALWAYS ranking among the US Top 500 girl names since statistics began, in 1880. Molly peaked in 1991 only to rise just as high again in 2011, and though softening retains a good measure of popularity and charm.

Natalie—a Franco-Russian name—became Americanized years ago and is one of those surprising names that's always ranked among the girls' Top 1000 names in the US.

Sasha, largely male in Russia--and also spelled Sascha and Sacha--is an energetic name that has really taken off for girls here, chosen by Jerry Seinfeld (using the alternate Sascha spelling) and other celebs. The Barack Obamas use it as the nickname for their younger daughter, whose proper name is Natasha. But in line with a trend toward softer-sounding boys' names like Asher and Joshua and thanks to Borat star Sacha Baron Cohen, Sasha also still has life as a boys' name too--it's popular in France for boys and girls almost equally.

Sean, after a long reign as one of the top Irish boys' names in the US, has now slipped as parents look to fresher Irish choices such as Liam and Aidan. In Ireland, Sean is still highly popular, but variation Senan, an Anglicized spelling of diminutive Seanan, is also stylish in Ireland. While Sean is the Irish form of John, Seanan and Senan may be thought of either as Sean diminutives or relatives of the Latin word "senator".
