Adeline has a lovely, old-fashioned "Sweet Adeline" charm, but has become so popular in the US under so many spellings and variations -- with Adalynn and Adalyn also popular -- that considered together it is far more popular than it first seems. Adorable nickname Addie is also pervasive.

Fiona entered the American consciousness with the opening of the 1954 Broadway musical Brigadoon, but didn't come onto the U.S. popularity list until 1990.

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.

Jean Harlow (born Harlean Carpenter), the original platinum blonde bombshell, was a symbol of 1930s glamour, a factor that first Patricia Arquette and then Nicole Richie and Joel Madden probably had in mind when they gave their daughters the distinctive surname name Harlow.

A true maverick of a girls' name — even more so with this spelling, the least common between Indie, Indy, and Indi.

Juliette, pronounced with the emphasis on the last syllable, adds a little something extra to Juliet. In the past years it has been rising up the chart.

June, a sweetly old-fashioned month name derived from the goddess Juno, was long locked in a time capsule with June Allyson (born Ella) and June Cleaver, but is rising again especially as a middle name.

A Top 100 name from 1896 to 1921, Leona reached as high as Number 72. Since then, Leona had seemed to be one of the most unfashionable of the pride of lion names, but singer Leona Lewis has done a lot to rejuvenate it. Leona returned to the Top 1000 in 2009 after decades of being away.

Lottie is a nostalgic great-grandma name that conjures up lockets and lace, and — like Nellie, Josie, Hattie, Tillie, and Milly — has considerable vintage charm.

The name of the Roman goddess of the moon, Luna is derived straight from the Latin word for moon, luna. Luna may be the name most likely to surprise someone from an older generation by its Top 10 status in the US and its widespread international popularity.

Vibrant, sassy, and bubbly, Ruby is a vintage gem that hasn’t lost any of its sparkle. Currently popular in a number of English-speaking countries, Ruby is proof of the 100 Year Rule, trending again for the first time since its heyday in the 1910s.

Sonora may be a more unusual and melodic choice than Sierra, but this Mexican state name may sound too much like Senora to work as a name.

Thalia was one of the Three Graces in Greek mythology, and also the Muse of comedy and pastoral poetry, making this a Hellenic choice worthy of consideration.
