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.

Alexander has been in a Top 25 boys' name in the US for 30 years now. But namers are still attracted to its imposing historic pedigree.

Alexis, a one-time exclusively-boys’ name, was more popular than its sister Alexandra for quite a while, but in recent years Alexandra has overtaken it once again. Alexis was a Top 20 girls’ name from 1994-2010 but has experienced a decline in popularity in recent years, though now it's one of the top unisex names.

Widely used here since the fifties, Allison -- a derivative of Alice -- has now been once again surpassed by the original Alice as parents embrace vintage revivals. Despite this, Allison's popularity has held strong, and it remains steadily within the Top 100. Allison's status is challenged by up-and-coming "-son" names, from Addison to Emerson. The freshest Allison alternative may be Ellison, which adds the appeal of trendy nickname Ellie as opposed to falling nickname Allie.

Though perhaps not as currently stylish as Ruby, Jade, or Pearl, Amber has a colorful history (remember the notorious Forever Amber heroine?). Unfortunately, it does come with the "Amber Alert" connotation for modern parents (and their children).

Amy is the English variation of the Old French name Amée—Aimée in modern French. Amée was a translation of the Latin name Amata, which derived from amatus, meaning "beloved." Other spelling variations include Amie and Ami.

Ann, the name of the sainted mother of the Virgin Mary, was among the top girls’ names for centuries, in both the original English Ann spelling and the French Anne. Both left the Top 100 around 1970 and show no signs of returning, with Anne is the middle of the US Top 1000 and Ann dropped out of sight. Once a go-to middle name, Ann has lost its stature in that position as well. Still, it's one of the most common names for girls of the 20th century.

It may have peaked at #1 for girls in 1991 and 1992 in the US, but Ashley actually has a long history as a male given name, as evidenced by the sensitive Ashley Wilkes in Gone With the Wind. It's always been more popular for boys in England and Wales, where it currently ranks at #414.

Beau suggests someone devilishly handsome, with a large measure of southern charm—a nice image to bestow on your boy. Often solely a nickname in the past, it's now standing firmly on its own. Beau has been on the Social Security list non-stop since 1969.

Beckett is one of the big baby name hits of the decade.

Blue suddenly came into the spotlight, as the unusual color name chosen by Beyonce and Jay-Z for their baby girl Blue Ivy. Blue is also a starbaby middle name du jour, used for both sexes in different spellings and forms, from John Travolta and Kelly Preston's Ella Bleu to Alicia Silverstone's Bear Blu. Dave 'The Edge' Evans named his daughter Blue Angel back in 1989.

Carver is an occupational name with an artistic bent, as is the newly arrived Painter, which has a fresher feel than the 1990's Carter. It also has eminent last-name links to botanist and educator George Washington Carver and short story master Raymond Carver.

Charlotte, the name of the young Princess of Cambridge, is the latest classic name to join Sophia, Emma, Olivia, and Isabella at the top of the popularity list. It is now among the most popular girl names in many English-speaking and European countries.

Chet is an old-fashioned short form that, ala Ned and Joe, is starting to sound cool again.

Clifford is beginning to overcome a slightly stodgy intellectual image and showing signs of possible revival. Kids might or might not like the association with the big red dog. In England, the Clifford family was a powerful family in the Middle Ages. In this country, it was well used for most of the twentieth century, peaking at Number 57 in 1909, but a Top 100 name through 1950. Most prominent American bearers: playwright Clifford Odets and jazz trumpet great Clifford Brown.

Cole -- a short name that embodies a lot of richness and depth -- has long been associated with the great songwriter Cole Porter. It's quite popular in Scotland.

Thanks to its dashing Anglo-Irish image — due partly to Colins Firth and Farrell — and its C-initialed two-syllable sound, Colin and its cousin Collin have enjoyed a long run of popularity, reaching as high as Number 84 in 2004.

Conrad has a somewhat intellectual masculine image, a solid name that has been consistently on the popularity lists, especially well used in the 1920s and 30s, and given a pop of rock energy by the Elvis-like character of Conrad Birdie in Bye, Bye, Birdie--("We love you Conrad, oh yes we do!").

Damian has sidestepped its demonic horror movie overtones, leaving a basically friendly and charming Irish image. A well-used upper-class name in England, it is growing in popularity here.

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.
