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.
 Adam, of course, is the first man God created. It is also a generic term for mankind. Adam did not hit the U.S. Top 100 until 1970, peaking in the early '80s at Number 18.

 Brookes have appeared on soaps like The Bold and the Beautiful" and All My Children, and on Melrose Place and One Tree Hill.

Chelsea is still being used, with about 400 baby girls named Chelsea in the US last year. But it was much more popular a few decades ago, peaking 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.

Chelsea

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. 
 
Daniel is derived from the Hebrew name Daniyyel, from the elements din, meaning "judge," and ’el, "God." The Book of Daniel in the Old Testament describes the Jewish prophet’s life of captivity in Babylon and visions of the last days of Earth. 
 Daniel was the name of one of the greatest biblical heroes, with the inspiring story of the prophet whose faith protected him when he was thrown into a den of lions. Yet Daniel does not seem as solemn and weighty a name as other Old Testament names like Abraham and Ezekiel. 

Popular since the days of Daniel Webster and Daniel Boone,
Daniel is a perennial favorite, in the Top 15 <a href="https://nameberry.com/boys-names">names for boys</a> every year since 1972. Daniel ranks first among all <a href="https://nameberry.com/search/boys-names/d">baby names starting with D</a>. 

Daniel's appeal is international, from Ireland to Israel, Finland to Chile. And its nicknames—Danny and Dan—make it sound even friendlier, though, as with other classics, many modern parents are opting to use the name in full.

Daniel

David is an enduring worldwide classic, used from ancient times to the present day.
 David is derived from the Hebrew name Dawid, believed to come from the root dôwd, meaning “beloved”. The first famous David was the Old Testament second king of Israel: the shepherd boy who killed the giant Goliath, and later a warrior, poet, and powerful leader, wise but humanly fallible. He is an important figure in Judaism, Islam and Christianity, and later inspired many works of art, including Michelangelo’s colossal sculpture.
 Since then, there have been countless Davids of note in history, literature, and popular culture, including the patron saint of Wales — a translation of the Welsh name Dewi — two kings of Scotland. Then there’s Copperfield, Crockett, Bowie, Beckham, Letterman, Grohl, and many more. Celebrities who have chosen it for their sons include Jennifer Hudson, Bar Refaeli, and J.K. Rowling.
 In its international forms, David is steadily popular around the world, and ranks in the Top 10 names in Brazil, Austria, Armenia, Croatia, Bosnia and Herzegovina, and Israel.
 In the USA, David has never been out of the Top 40 boy names, but was at peak popularity in the mid-twentieth century, ranking in the Top 10 from 1936-1992. This means that, although it’s still given to thousands of boys each year, it has an “older man” feel to it. It ranks highest in states with a large Jewish population, and is still a Top 10 name in New York.
 After Daniel, David is the second most popular <a href="https://nameberry.com/search/boys-names/d">boy name starting with D</a>. Although fading a little in popularity, it remains a serious-yet-friendly classic with deep roots.
 If you’re looking to update David, perhaps as an honor name, the freshest alternatives are surnames deriving from David, including Dawes, Dawson, and Davies. You could also try an international variation, like Welsh Dai or Finnish Taavi.

Delaney has been a popular surname-style choice since 90s, when it joined other Irish surnames such as Cassidy, Kennedy, and Mallory on the US Charts. Buoyant, bright, and cheerful, it ranks in the US Top 250 and is given to nearly 1300 babies every year.

 Alternatively, pop cultural influences might have driven the name up the charts, with singer Delaney Bramlett releasing new music, actress Dana Delany starring in the successful TV drama, China Beach , and the Delaney family in The Baby Sitters Club book series.

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.
 
What is Molly short for? Molly originated as a diminutive of Mary, spawning from medieval variations Malle and Molle. Molly has been used as a stand-alone pet form of Mary since the Middle Ages, and has been consistently popular as an independent name in the U.S. over the past several decades.
 Likable and down-to-earth, mild yet saucy, Molly has a distinctly Irish feel as well, with such Gaelic associations as 'Sweet Molly Malone' and the martyred reformers known as the Molly Maguires. In the Jewish culture, Molly Goldberg was an early television personality. 
 Other references include the Revolutionary War heroine Molly Pitcher and the Molly Bloom character in James Joyce's Ulysses, as well as characters in novels by Fielding, Hardy, George Eliot, Dickens and Thackeray. More recently, "Good Golly, Miss Molly" was a Little Richard hit and Molly Ringwald a celebrity bearer.
 Amanda Peet is the mother of a Molly, as are Monica Potter and Veronica Webb.

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.
 An Old Lady Name in the 1950s, Natalie reversed course and has been more popular than ever in this century, though it's fallen off a bit from its peak in 2008.
 Natalie is the French variation of Natalia, a name originally derived from the Latin phrase natale domini, meaning "birthday of the Lord." It was historically given to girls born around Christmas for this reason. 
 Natalie was Cameron Diaz's character in Charlie's Angels, and was attached to first Natalie Wood, then Natalie Cole (named for her father), and now Natalie Portman. 
 Along with Cole, Natalie has other musical ties to singers—Maines, Imbruglia and Merchant -- and to a not too flattering hit song by Bruno Mars. Natalie has been a TV regular ranging from the lovable character on the old The Facts of Life, to Monk to Orange is the New Black.
 
Nathalie is an additional, though less common, spelling of the name.

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.
 Another notable female bearer is 2006 Olympic silver medalist skater Sasha Cohen; Sasha Alexander, on the TV show Rizzoli & Isles, was born Suzana. And Sasha Fierce is the name of Beyonce's alter ego.
 Sasha was as high as 147 in 1988.

Sean, after a long reign as one of the top <a href="https://nameberry.com/list/328/irish-baby-names-for-boys">Irish boys' names</a> 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".
