Sophia, which was the Number 1 girls' name in the US from 2011 to 2013, is among the top girl names in the Western World, with a sensuous sound and high-minded meaning. A real winner, Sophia reached the top of the charts without losing any—okay, much—of its sophisticated beauty.

Wren, a lilting songbird name, could be the next Robin. Wren entered the Top 1000 for the first time in 2012 and is among the new wave of popular English names for girls.

Talia is derived from the Hebrew elements tal, meaning "dew," and yah, in reference to God. In the mythology of one ancient sect, Talia was one of ten angels who attended the sun on its daily course. The occasionally homophonous name Thalia has unrelated Greek origins.

Cleo, one of the few girls' names to boast the cool-yet-lively o ending, is of course short for Cleopatra, the name of one of the most powerful women in history.

You might think of Harper as the hottest name of the last decade, jumping from obscurity to the Top 10, where it remained until last year.

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.

Elliot (which boasts several spellings depending upon how many 'l's or 't's you want to use) is a winner -- it has the ideal quality of being neither too common nor weirdly unique. Elliot had a style boost back in the early 1980s via the young hero of the movie E.T. , who was named Elliott. Since then there have been Elliots on Law & Order: SVU and Mad Men.

Elena is at its most popular point ever in the US, thanks to its cross-cultural appeal and the overall popularity of El- names. It's more international than Ellen or Eleanor, but still accessible.

Abigail has been in for so long -- the name has ranked in the US Top 100 since the late 1980s -- it's amazing that it isn't more out by now. But Abigail's biblical and historic roots make it a fashionable classic rather than a passing fad.

Aria is a multi-cultural name with two extremely popular versions: this more word-like one along with Arya, the spelling used for the feisty young heroine of Game of Thrones.

Luke is a cool-yet-strong Biblical name with a relaxed cowboy feel, which has been on the rise since the advent of Luke Skywalker.
