Heroines from Barbie

Fallon is one of several boyish surname names introduced in the over-the-top 1980s nighttime soap Dynasty: they sounded cutting-edge at the time, but no longer.

Genevieve is derived from the Germanic medieval name Genovefa, or Kenowefa, which consists of the elements kuni, meaning "kin", and wefa, meaning "woman." The medieval saint Genevieve, patroness of Paris, defended the city against Attila the Hun through her rational thinking, courage and prayer.

Hadley, most famous as the name of Ernest Hemingway's first wife, is more sophisticated, professional, and modern than cousins Harley, Haley, or Hayden. The hit book The Paris Wife, a novel by Paula McLain told from the point of view of Hadley Hemingway (born Elizabeth Hadley Richardson), has helped popularize the name, which also appears on the vampire show True Blood. Hadley could become this generation's Hailey. Adley, a mashup of Hadley and Addie, has also appeared on the scene.

There are no less than ten different variations of Hailey on the current Most Popular list, but this is the spelling that brought it into the Top 10 of 2010, although it has recently dipped a bit in popularity. So, although Hailey has a shiny, unpretentious charm, its mass popularity makes it very much of the moment. Look for the Hailee spelling to rise via Hailee Steinfeld, the young actress Oscar-nominated for her performance in True Grit.

Whether it's pronounced with an "een" or an "aine" or an "enn" sound at the end, Helene doesn't feel as current the more forthright Helen or the airier Helena. Helene reached a high of Number 228 in the US in 1916, when ene, ine and een names were all the fashion, and stayed in the Top 500 until 1962, making a final exit in 1970. It still ranks well in its native France, and even more in Norway (#70). Model Heidi Klum's daughter 'Leni' has Helene on her birth certificate.

Reddish dye that sounds as if it could be a real name — of the outdated, Old World, Yetta-Hedda variety.

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.

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.

This newly invented name is most likely a combination of Jane and Vanessa. Though it may not have as long of a history as more traditional names, Janessa has been a staple on the bottom half of the US Top 1000 since the mid-1980s. Perhaps surprisingly, it peaked at Number 524 in 2004.

Kara and the soundalike (though not necessarily related) Cara are among the most multi-cultural names around. Cara has roots in Latin, Italian, Irish, Spanish, and Portuguese, and Kara can be viewed as simply as K-starting version of Cara.

Kathleen is the early Irish import version that came between Katherine and Kaitlin, and which hasn't been used in so long it's almost beginning to sound fresh again. It was a surprise pick by one of the hip Dixie Chicks, Martie Maguire. Kathleen was a Top 10 name from 1948 to 1951, and it is the subject of several old sentimental songs, such as "I'll Take You Home Again, Kathleen."

Once the quintessential bouncy teenager name, Kelly helped launch the trend of unisex Irish names . But it now takes a backseat to more substantial surname names like Kennedy.

Kiera entered the American popularity list in 1988, though it lags behind the alternate spelling Keira, largely due to the fame of actress Keira Knightley.

A unique combination of a surname feel and dainty femininity. It's currently associated with actress Lacey Chambert.

Liana is a pretty and graceful name — it's a flowering tropical vine — making a quiet comeback. Its connection to nature is one plus, and many parents like this kind of nonspecifically international name.

A name from the East African Kikuyu language with a sweet meaning; and a simplified spelling of McKenna.

Mariposa is a rare, romantic choice with an intriguing meaning.
