Operation: Baby 2020 (Girl)

Adalyn is one of a large group of Ad-beginning names for girls, which include Adeline and Adalynn and Adelaide and Addison — essentially, anything leading to the popular nickname Addie is in. Adalyn is a beautiful name, but be prepared to have to spell it out for people often. Adalyn entered the charts in 2007 and rose quickly, but has been fairly steady in the mid 100s for nearly 10 years now.

Newly fashioned but familiar and with an on trend, unisex feel, Addison seems like the perfect solution for anyone who can’t decide between Madison, Adeline, and Alison.

Adelaide is now heading straight uphill on the coattails of such newly popular sisters as Ava, Ada, and Audrey, and in the company of Adeline and Amelia. It was chosen by actress Katherine Heigl for the name of her second daughter.

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.

Adeline has a lovely, old-fashioned "Sweet Adeline" charm, but has become so popular in the US under so many spellings and variations -- with Adalynn and Adalyn also popular -- that considered together it is far more popular than it first seems. Adorable nickname Addie is also pervasive.

Adeline in all its forms, including Adelyn, is rocketing up the list, but we do prefer the original to the variations. Or you might consider varying it yet further to Adelia, Adele, or Adelaide. Or lengthen it to Madeline/Madelyn.

This a-ending feminine form of Adrian, from the northern Italian city of Adria, is a soft and lovely Italian choice. It appears as a character in Shakespeare's The Comedy of Errors.

A long-integrated French feminine form of Adrian, now overshadowed by the a-ending version, but still a valid option, with considerable substance and dignity—though these days more parents would probably choose Adriana.

Amy was a 1970s favorite, and French spelling Aimee peaked in the same decade.

Alaina, part Alana and part Elena and maybe also a little bit Elaine, is one of the many feminine forms of Alan (or its French form Alain) that have grown in popularity over recent decades, surpassing the male original. Not quite fashionable but also not quite un, Alaina is a choice that may feel more distinctive than it really is.

Alana, in all its various spellings, was at one time reserved for daughters of dads named Alan, but is now much more widespread. It came into prominence via model/actress/celeb spouse Alana Hamilton Stewart.

Alexa was a steadily popular modern classic until Amazon's virtual assistant Alexa was released in 2013. It remains relatively well used in the US despite this, though its standing keeps dropping for obvious reasons. Too bad, because it's a strong and pretty name (which is probably why Amazon used it.)

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.

Alia is the most classic and feminine form of Ali, one of the 99 attributes of Allah within Islam. Meaning "supreme, exalted, high, sublime", it is pretty, powerful and spirited.

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.

In music, the term allegro means "quickly, lively tempo," which makes this quintessential Bohemian ballet dancer's name all the more appealing. Allegra is one of the most distinctive yet accessible girl names starting with A.

Althea is a poetic, almost ethereal name found in Greek myth and pastoral poetry, associated in modern times with the great tennis player Althea Gibson, the first African-American to win at Wimbledon.

Alyssa was in the Top 20 from 1997-2010 and peaked as the 11th most popular girls’ name in 1998 and 1999 but has become less popular in recent years. It's related to the flower alyssum as well as to the classic Alice and variants. Alyssa Milano helped give it a bounce back when she was still a child sitcom star.

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).
