Characters from The Selection

The origin of the name Aaron is debated—some say it was derived from Hebrew, while others claim it originated in Ancient Egypt. In the Old Testament, Aaron, the older brother of Moses who was appointed by God to be his brother's spokesman, was the first High Priest of the Israelites. The Hebrew version is Aharon—in Yiddish it can be Aaran—and the name appears in Arabic as Haroun or Harun.

Gently old-fashioned stand-alone nickname that owes its popularity to mega popular Abigail.

This Spanish month name has been quietly used for several years now in the US.

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.

Credit the award-winning single-named British singer for taking the girls’ name Adele from a quiet semi-retirement back into currency. Adele reentered the US Top 1000 popular baby names in 2011 and has remained there ever since.

While theoretically unisex, this surname name has been edging up the girls’ names list, perhaps originally as an Ashley substitute. One quality in Ainsley's favor: It's remained steadily popular -- but not TOO popular -- for more than 20 years now, ranking consistently around Number 400. That makes it stylish and familiar without showing up everywhere.

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.

Alice is a classic literary name that's both strong and sweet, ranking in the US Top 100 and popular throughout the western world. Alice is derived from the Old French name Aalis, a diminutive of Adelais that itself came from the Germanic name Adalhaidis, which is composed of the Proto-Germanic elements aþala, meaning "noble," and haidu, "kind, appearance, type."

Alicia is a Latinized variation of Alice, a name ultimately derived from the German Adalhaidis. It emerged in the 19th century, but the 20th saw many spelling evolutions for Alicia, including Alecia, Alisha, Aleesha, and Alysha. Alyssa originated as a form of Alicia.

A rarely used play on Amber, making it more feminine and both more modern and old-fashioned at the same time.

Given to children of both sexes as far back as colonial times, this carries a lot of baggage. However, parents continue to take the risk. Actress America Ferrera may be have inspired some families to choose the name. Ferrera's Honduras-born mother shares her unusual name.

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.

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.

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 but Anne is still among the most classic names for girls, although others are more likely to choose the original Hannah, the Anna variation, or even Annabel or Annabella.

Annika is a surprise hit of recent years, inspired by golfer Sorenstam; for Trekkies, it was also the name of a 'Star Trek:Voyager' character. Some people's first memory of it might be as Pippi Longstocking's friend. A nice namesake for an ancestral Ann.

Antonella is a feminine form of Anthony growing in popularity throughout Latin America as well as in the US.

We usually think of place-names as a modern invention, but in fact Arizona ranked on the US Top 1000 from its inception in 1880 until 1911, when it vanished below the surface. It peaked at Number 510 in 1882, before Arizona became a state. One notorious vintage bearer: criminal "Ma" Barker, born Arizona Clark.

Arthur, once the shining head of the Knights of the Round Table, is, after decades of neglect, now being polished up and restored by stylish parents, inspired perhaps by the new generation of royals. Arthur has led the list of possible names for the young British princes, chosen as a middle name for Prince Louis, son of William and Catherine, Prince and Princess of Wales.

Ashley was a sensation in the 1980s and 1990s; it hit Number 1 in 1991. Ashley is still pretty but more and more parents are turning to newer names like Ashlyn and Aubrey, and spellings such as Ashleigh and Ashlea. If you hear the name Ashley in a playground today, it's more likely to be the mom than the little girl.

As trendy as the chic Colorado ski resort and film festival, Aspen is fast becoming more popular for girls than for boys, but this nature name would work equally well for either.
