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.

Lily is the most popular of the popular delicate century-old flower names now making a return, thanks to its many irresistible attributes: a cool elegance and a lovely sound, a symbol of purity and innocence, and a role in Christian imagery.

Evangeline is a romantic old name enjoying a major comeback, thanks to its religious overtones, Eva's popularity, and the star of the TV megahit Lost, Evangeline Lilly. Evangelia and Evangelina — two variants of Evangeline — are sure to tag along for the ride.

Seraphina is one of the most-searched name on Nameberry, destined for even greater popularity. The highest-ranking angels, the six-winged seraphim, inspired the lovely name Seraphina.

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 truly international choice, the sweet and simple Mira has its origins in Sanskrit, Latin, Slavic, and Arabic, just to name a view. With its arty aura and succinct look, it makes a versatile option, much like the similar Nina and Mina.

The goddess name Aurora has consistently been on the US popularity list since the nineteenth century, but has really taken off in the past 30 years. Aurora also enjoys remarkable international popularity, ranking in the Top 100 throughout the English-speaking world as well as in Italy, Spain, Norway, Switzerland, and several other European and Latin American countries.

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.

Vera was the height of fashion in 1910, then was for a long time difficult to picture embroidered on a baby blanket. Now, though, it has come back into style along with other old-fashioned simple names such as Ada and Iris.

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.

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.

Maisie, a charming name long popular as a nickname for Margaret or Mary, entered the Top 1000 as itself ten years ago and continues to rise. Game of Thrones star Maisie Williams helped propel the name back into the limelight, along with the that of her character, Arya.

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.

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.

Vivienne is an elaborated Gallic version of the name Vivian, chosen first by Rosie O'Donnell for her daughter and then catapulted to superstardom when Brad Pitt and Angelina Jolie used it for their twin daughter. An adult namesake is the British designer Vivienne Westwood. Rosie O'Donnell also has a daughter named Vivienne, known as Vivi.

Molly is one of the original nickname names, ALWAYS ranking among the US Top 500 girl names since statistics began, in 1880. Molly peaked in 1991 only to rise just as high again in 2011, and though softening retains a good measure of popularity and charm.

Willa has become increasingly fashionable, with its combination of Willa (born Wilella) Cather-like pioneer strength and the graceful beauty of the willow tree.

Simple, classic, strong, and versatile, Jane has shrugged off her plain associations to become a short, punchy name with plenty of literary significance. Calling to mind Jane Austen and Jane Eyre, this charming choice is in the Top 300 in the US and The Netherlands, but a currently underused option elsewhere.

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.

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.
