Isla is a hit name throughout the English-speaking world but hasn't found the same popularity in other western countries, perhaps because its spelling and pronunciation don't make sense for those whose native language is not English. Think island without the final two letters.

Iris has so much going for it. It's a fashionable flower name. It's a mythological name, from the Greek goddess of the rainbow. And it's a classic name, always ranking in the girls' Top 1000 but now at its highest point ever.

Ada is one of the classic baby names for girls that is suddenly super stylish again. A favorite at the end of the nineteenth century, Ada is an alternative to the over-popular Ava. Ada is also part of the trend toward simple, old-fashioned names beginning with a vowel, like Ivy and Ella.

Frances, a soft and gentle classic last popular a hundred years ago, is trending again. The cool nickname Frankie is one reason for the revival of Frances, adding lightness and sass to a serious name. Frances is the feminine form of Francis, the English variation of the Latin name Franciscus. Franciscus, meaning "Frenchman," was taken from the Germanic tribe the Franks, which got its name from the francisca, the axe they used in battle. Until the seventeenth century, the spellings Frances and Francis were used interchangeably for both sexes.

Maybe it's because she shares that winning -elle sound with Isabel and Bella, but Estelle is no longer seen as a muumuu-wearing canasta player of a certain age (think George Costanza's mother on Seinfeld or Joey Tribbiani's talent agent in Friends). This could be in part thanks to the young Royal Couple of Sweden, who chose it for their firstborn daughter, or the single-named British R&B singer. It reentered the US Top 1000 in 2012 after a nearly fifty-year absence.

A lovely musical name (remember the old Eric Clapton-Derek & the Dominos song?), Layla's seen a significant surge in popularity, partly partly all names with a double L are stylish, and partly because all the forms of the name push it into the Top 15 for girls.

Noelle is the feminine variation of Noël, a masculine given name derived from the French word for "Christmas." As a word, Noël originated as a variant of nael, which evolved from the Latin natalis, meaning "birth." Noelle and Noel have traditionally been given to children born around Christmastime, particularly in the Middle ages.

The skyrocketing success of singer Norah Jones brought this spelling of the name onto the pop charts in 2003. As well as being a spelling variant of Nora in English, it's also an alternative transcription of the Arabic name Nura, from Nur/Noor "light".

One of the glamour girl names of the Rita Hayworth 1940s, Rita was once a Top 50 name and stayed on the SSA list until 2002.

This Scandinavian name was made famous in English-speaking countries as the name of the dog in the "Thin Man" series. Danish actress Asta Nielsen was another famous bearer. Asta can be considered as a short form of Astrid or Augusta.

In 2010, baby boys named Ari outnumbered baby girls 4 to 1; today, there are nearly equal numbers of boys and girls named Ari. And that's only counting the babies who receive Ari as a full name. Ari can also be short for not only Ariel but Aria, Arya, Ariana, and any other name starting with Ari. Ari entered the US Top 1000 for girls in 2016.
