Once the most popular month names, April has been overtaken by June (for girls) and August (for boys), as well as the charmingly old-fashioned May. Literary reference: the heroine of the book and movie Revolutionary Road, and there have been Aprils on Parks and Recreation, Glee, and The Vampire Diaries. Trivia note: comedian Ralphie May named his daughter April June May.

The gorgeous Angelina Jolie has promoted the star power of her name and changed Angelina's image from delicate to intense, from older Italian mama to stylish multi-cultural child. Kids might relate to the dancing mouse in the series of charming children's books, Angelina Ballerina, or to the Harry Potter character, Angelina Johnson Weasley, a member of Dumbledore's army.

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.

Widely used here since the 50s, Allison — a derivative of Alice — has now been once again surpassed by the original Alice as parents embrace vintage revivals. Despite this, Allison's popularity has slipped only slightly.

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.

Alison has been long popular in Scotland and widely used here since the fifties. This more feminine medieval elaboration of Alice had long surpassed the original in popularity, but now sounds a tad dated in the U.S., with Alice having leapfrogged back over Alison, Allison, Alicia and other variations.

This Italian and Portuguese variant of the classic Alexandra softens the classic name, while still maintaining its strength and dignity. Currently in the US Top 500, it also ranks in Brazil and Italy. Instead of Lexi, this form could get you to nicknames Essie or Alessa.

Ariel is a male Biblical name, seen there as the messenger of Ezra, and also used as a symbolic name for the city of Jerusalem, while Shakespeare used it for a (male) sprite in The Tempest.

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.)

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

This still attractive place name was one of the first to gain popularity, though it now probably owes some of its favor to the similar Aisha. Asia ranked as high as Number 195 on the US baby names popularity list in 1997.

Cute nickname of Angela and other angelic names, Angie is now being used on its own, although its popularity has fallen in recent years. That said, Angie is one of those surprising classics, hanging on in the girls' Top 1000 continuously since its inception in 1880.

This variation of Annemarie ensures the name is pronounced with four syllables. Classic and sturdy but with a playful, spirited sound, Annamarie is popular in Czechia, where it is also written as Anna Marie.

Angel is one of those names that has a very different trajectory for girls and boys. As a female name, it was most popular in the US from the 1970s until the turn of this century, almost breaking into the Top 100 at its peak in 2001 but then beginning a long slide down the list.

A popular spelling variation of Adriana.

The original Allison was a Top 50 name from the 1980s through 2016, and Allyson is one of the many spelling variations parents used to put a more unique spin on the original.

A pretty smoosh name predominantly used by Italian Catholics.

Alison by any spelling is now considered more of a mom name than a baby name. It's been trending downward for more than a decade, though it still makes the Top 1000.
