Decade Ambiguous

Name of an Old Testament soldier that's been also used as a girls' name in modern Israel. An alternate spelling is Adinah. Some mistake Adina and Adinah to be the root of Dinah, but the Biblical name Dinah is borne by a different figure and has a different meaning. You can consider the modern short forms Dena and Dina as stemming from either Adina or Dinah.

In its three most popular spellings -- Alan along with Allen and Allan -- this midcentury favorite has tended to skew older. It was a Top 100 name from 1938 to 1971, peaking at Number 40 in 1951. Alan has had leading roles on recent TV, in shows like Two and a Half Men, 24 and Boston Legal.

Alba is quietly making a behind-the-scenes comeback, perhaps thanks to actress turned baby-product mogul Jessica Alba. Last on the Top 1000 a century ago, the name was given to nearly 200 baby girls in the US last year. Alba might be tomorrow's successor to Ava and Ella. In Spain, Alba ranks among the Top 20 girls' names. Alba is the name of a character in The Time Traveler's Wife.

Confident and compact, Ana is a widely used variation of the Biblical Hannah. Favored in Spain, Slovenia, Bosnia, Portugal, and Croatia, this shorter spelling has the same substance and versatility of its longer counterparts.

Anna has become the dominant form of the Ann family, offering a touch of the international to English speakers and a bit more style than the oversimplified Ann or Anne.

Substantial, strong, and enduring, Anthony has remained a perennially popular name over the last century. With just a hint of playfulness and just a touch of clunky-coolness, Anthony is a versatile choice that seems comfortable anywhere.

Antonia is stronger than most feminized boys’ names, reflecting the pioneer spirit of Willa Cather's classic novel My Antonia. Antonia is hovering near the bottom of the US popularity list, which may be an excellent reason for you to use it.

Augustine is more substantial (and saintly) than August, less pretentious than Augustus, and, along with its nickname Gus, is definitely a viable choice.

Tough-yet-cuddly Bruno is an international name even in its origins: it derives from the Germanic word for "brown" plus a Latin ending, and was borrowed as a color word in many European languages.

Calvin is a slightly quirky but cozy name that has a fashion edge thanks to Calvin Klein. It has been steadily on the popularity list since records were kept, never lower than Number 250, peaking in the 1920s, the era of the Calvin (originally John Calvin ) Coolidge presidency.

At one time just the sound of the name Camille could start people coughing, recalling the tragic Lady of the Camellias, the heroine played by Greta Garbo in the vintage film based on a Dumas story, but that image has faded, replaced by a sleek, chic, highly attractive one.

Catherine is one of the oldest and most consistently well-used girls’ names, with endless variations and nicknames. The Catherine form feels more gently old-fashioned and feminine than the more popular K versions. Most stylish nickname for Catherine right now: Kate...or Cate, a la Blanchett.

Cecilia is a lovely classic name deservedly enjoying a new turn in the sun. Always among the Top 500 girls' names in the US, Cecilia is now at its highest point ever.

Celeste is a softly pretty and somewhat quaint name with heavenly overtones, which kids might associate with Queen Celeste of Babar's elephant kingdom. She's a light and lovely choice that's finally getting noticed.

Charles derives from the Germanic name Karl, meaning "man" or "free man", and is a royal name in multiple European countries. A famous early bearer is Charlemagne, King of the Franks and Lombards and then Roman Emperor in the 8th-9th centuries.

Clark seemed to have been Gone with the Wind, but parents looking for a short, strong boy's name are now beginning to appreciate its cool combination of Gable charm with Superman power.

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!").

Corinne is one of the names that, it might surprise you to learn, has never been off the US popularity charts. Its most popular year was 1926, when it ranked Number 249. Corinna is another pretty ancient form of the name, technically a diminutive.

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.

Before there was Aspen, Denver was the Colorado city name of choice, and it reentered the US Top 1000 in 2015 after a 14 year absence as a stylish two-syllable boys’ name with its trendy -er ending. Its decade of greatest use was the 1920s, when it reached as high as Number 422.

Duncan is jaunty, confident, and open, a Scottish royal name that's brimming with friendly charm and makes it into our golden circle of names that are neither too popular nor too strange. Popularity aside, Duncan is one of the most classic Scottish names for boys.

This spelling of the classic name is found in France, Germany, Greece, and other cultures, and is worn by such notables as Elisabeth Kubler-Ross, Elisabeth Shue, Elisabeth Moss, and Elisabeth Hasselbeck. The name's pronunciation is usually just like the Z version, but some parents choose this because they want to discourage the Liz or Lizzie short forms and so pronounce it as if it has Lisa in the middle.

Elizabeth is one of the most popular girls' names of all time, the female equivalent of James or William. Yet Elizabeth has so much going for it—rich history, broad appeal, and timeless style—that no matter how many little girls are named Lizzie, Eliza, and Beth, you can still make Elizabeth your own.

Lost in limbo for decades and decades, Elsa now stands a good chance of following along in the progression from Emma to Ella to Etta, thanks to the ice queen heroine who "Let It Go" in the wildly popular Disney movie Frozen. The name shot all the up to Number 286 (its highest ranking since the 1890s) in the year after the release of the movie, though it's now dropped back down the list in the US.

Forrest is one of the earliest appealingly sylvan, outdoorsy choices, borne by newsman Sawyer, actor Whitaker, and football Hall of Famer Gregg. Forrest Gates was a character on "Buffy the Vampire Slayer."

Iconoclasts though we may be, we like Fred, we like Frank, and we like George, which was among the Top 10 from 1830 to 1950, when the number of little Georges started to decline. Solid, strong, royal and saintly, yet friendly and unpretentious, we think that George is in prime position for a comeback, especially since it was chosen by Britain's royal couple.

Helena is one of those classic names that just misses making the US Top 1000 girl names for its entire history, falling off for a single year in 1992. Since then it's been drifting lazily up the charts, and makes a perfect choice if you want a name that both fits in and stands out.

Jack may have fallen from its Number 1 place in England, but in the US it's as popular as it was at its height in the 1920s and 1930s. A durable, cheery, everyman form of John, Jack ranks as one of the most popular boy names starting with J.

James for a girl? Believe it or not, this is one of the boy names for girls" gaining a lot of attention these days, since Blake Lively and Ryan Reynolds shocked the world by choosing it for their eldest daughter in 2014 (after his late father).

Most modern parents would drop the Jo, leaving the superpopular Ella.

Johanna is the version of this name used in Holland, Germany, and Scandinavia. The extra h makes Johanna a slightly more dignified version of Joanna.

John reigned as the most popular of all boys' Christian names for 400 years, from the time the first Crusaders carried it back to Britain until the 1950s. Then American baby namers finally seemed to tire of this straight-arrow, almost anonymous John Doe of names, replacing it with fancier forms like Jonathan and the imported Sean and Ian.

Joseph is one of the most classic names in American nomenclature, popular with parents from many ethnic backgrounds and having dual-religious appeal.

Katherine is one of the oldest, most diverse, and all-around best names: it's powerful, feminine, royal, saintly, classic, popular, and adaptable. Long one of the top girls' names starting with K, Katherine has now been unseated on the popularity list by upstarts Kennedy and Kinsley, but a dip in popularity only adds to its charm.

Malcolm is a warm and welcoming Scottish appellation (originally Mael-Colium) that fits into that golden circle of names that are distinctive but not at all odd. A royal name in Scotland, Malcolm is also a hero name for many via radical civil rights activist Malcolm X.

It's been used as a first name since the nineteenth century and has been on the Social Security list since it started to publish its data in 1880.

A feminine form of Martin, this strong and zestful sounding name is popular in Argentina, Chile, Spain, and Italy, where it ranks in the Top 30. Also familiar in Czechia, the UK, Slovakia, and Switzerland, it has never made it big in the US, and fell out of the charts back in the 2000s.

Ultimately associated with Mars, the Roman god of war and with the 3rd century patron saint of Rome, it has also been borne by two notable tennis players, Martina Navratilova and Martina Hingis.

Patrick, long tied to a hyper-Irish image, is enjoying something of a renaissance as a stylish classic, as it has long been considered in England. Along with such choices as Charles and George, Patrick has escaped overuse in recent decades.

Raphael is a romantic archangel name that sounds both artistic and powerful. Raphael is also a great cross-cultural choice, with significance for people with both Latinate and Jewish roots, plus plenty of grounding in the English-speaking world.

Samuel has been so popular for so long that it's hard to believe it's still climbing, at its highest point since the 1890s.

According to the Book of Genesis, Sarah was originally called Sarai, but had her name changed by God to the more auspicious Sarah when she was ninety years old.

Simon is pure and simple (not in the nursery rhyme sense), and an appealingly genuine Old and New Testament name that's not overused. These factors make Simon a stylish yet classic choice.

Susanna is an old and under-appreciated name, perhaps because of the recent overpopularity of Susan, that is certainly due for a comeback.

Thaddeus, a distinguished, long-neglected name, has several areas of appeal: a solid New Testament legacy, a nice antique feel, and the choice of several more modern nicknames and international variations.

A solid classic with plenty of history, Thomas strikes the balance between strength and gentleness. A favorite in the UK, a staple in France, and Australia, and never absent from the US Top 100, Thomas feels like a safe bet and a name that fits into any era.

A short but sophisticated, long-neglected name you might want to consider.

Victor is one of the earliest Christian names, borne (as Vittorio) by several saints and popes, symbolizing Christ's victory over death. It has been quietly in the Top 200 since 1880, but just recently has taken on a cool edge by fashionable parents in London and seems ripe for a similar reevaluation here too.

Vincent is a name with a complex image. After being quietly used for centuries, it is suddenly seeming stylish, along wih other V names. Even the nickname Vince has been given a reprieve via actor Vince Vaughn and country singer Vince Gill. Vin Diesel was born with the more prosaic name Mark Vincent.

Reminiscent of the Old West, with rugged charm and a gentle, easy-going feel, Wesley has long been a staple on the US charts.

William is one of the most enduring of classic names for boys. It's also among the most popular boys' names, as American parents see it as being ideally conservative yet contemporary, and hands-down the most popular baby name beginning with W of all time.
