Penelope is an unlikely 21st century baby name success story. Off the Top 1000 for 25 years, Penelope jumped back on in 2001 and has been heading uphill ever since, propelled by the trend for mythological names, Spanish actress Penelope Cruz, and some high-profile celebrity babies.

Audrey is one of the girls' names that have been rising due to their connection to Old Hollywood glamour — in this case the eternally chic and radiant Audrey Hepburn. Audrey has another very different appeal as one of the elite group of girl names that mean strong, brave, or powerful.

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.

Chloe is a pretty springtime name symbolizing new growth. Though slightly off its peak in the Top 10 in 2010, Chloe still ranks in the Top 20 and is solidly a modern classic.

Caroline is a perennial classic, one of the elite group of girls' names that's ALWAYS ranked among the Top 1000 and that's been in the Top 100 since 1994. Elegant yet strong, Caroline calls to mind the Kennedy Camelot years and Princess Caroline of Monaco.

Emily may have dropped somewhat in the current standings, but it was the most popular girls' name for over a decade because it appeals on many levels: Emily is feminine, classic, simple, pretty, and strong. Emily is Number 1 among Gen Z names. It also has those nice literary namesakes, like Emily Dickinson and Emily Brontë.

Mia is an appealingly unfussy multicultural name that has enjoyed a meteoric rise up the charts and is now firmly among the ten top girl names. Mia has surpassed its mother name Maria as the Number 1 girls' name starting with M.

A familiar name with a unique look and sound about it, Naomi combines a gentle cadence with classic strength. It was once a primarily Jewish name from the Old Testament, borne by the mother-in-law of Ruth, symbolically given to girls on Shavuot (a holiday held around the wheat harvest) when the story of Ruth is read in the synagogue.

Ella is a sweet, simple name that owes much of its current popularity to the popularity of other names, from Emma to Bella to Emily to Ellie.

Rose is derived from the Latin rosa, which referred to the flower. There is also evidence to suggest it was a Norman variation of the Germanic name Hrodohaidis, meaning "famous type," and also Hros, "horse". In Old English it was translated as Roese and Rohese.

Isabella has been a Top 10 name for girls in the US for two decades now. The Latinate form of Isabel, a variation of Elizabeth which originally derived from the Hebrew name Elisheba, Isabella reigned as Number 1 in 2009 and 2010.

An ancient tree that figures in literature from Shakespeare to Harry Potter and is believed to possess magical powers, Willow is a lovely name, as graceful as its inspiration.

A hot starbaby name – chosen by Kelly Ripa, Chris Rock, Lisa Bonet, Denise Richards and Charlie Sheen, Carnie Wilson, and Annie Lennox, and used as the nickname of Madonna's Lourdes – Lola manages to feel fun and sassy without going over the top. Be warned, though: "Whatever Lola wants, Lola gets," to quote a song from the show Damn Yankees.

Flora, the name of the Roman goddess of flowers and spring, who enjoyed eternal youth, is one of the gently old-fashioned girls' flower names that's making a big comeback. Short and sweet, it joins Cora, Florence, Iris, and Ivy in the charts.

Maya, which has an almost mystical image, has been steadily climbing in popularity in the US and the English-speaking world, along with a range of other countries, including France, Germany, Israel, and Brazil. It's ranked in the US Top 100 since the turn of this century, but has never risen to the top of the list, which you may consider a good thing.

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.

Elizabeth is one of the most popular girls' names of all time, the female equivalent of James or William. Yet Elizabeth has so much going for it—rich history, broad appeal, and timeless style—that no matter how many little girls are named Lizzie, Eliza, and Beth, you can still make Elizabeth your own.

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.

Scarlett Johansson is doing more for this sparky southern name than Scarlett O'Hara ever did. Since the turn of the 21st century, Scarlett has gone from an obscure literary name to one of the most popular girls' names starting with S, right after longtime favorites Sophia and Sofia.

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.
