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.

Pared-down form loses none of the name's grace or power. Ana is one of the most popular Spanish names for girls in the US.

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.

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 "freeman", 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.
