The Twelve Dancing Princesses

In the USA, Blair is gaining momentum, rising quickly for the last 10 years and likely to continue to climb.

Among the Top 20 names of the 1990s, today's Courtney is more apt to be the babysitter than the baby. Courtney has dropped since its peak at Number 17 in 1995. Familiar from Courtney Love and Courtney Cox.

Delia is a somewhat neglected southern charmer that stands on its own but also might be short for Adelia or Cordelia.

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.

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.
