Bubbly, bright, and versatile, Phoebe is a name with mythological, biblical, and literary ties. Used since the 17th century, it fell out of fashion in the US during the '60s, only to be revived after it appeared in the 90's TV favorite, Friends.

Riley—an upbeat, friendly surname name—is red hot for girls and still going strong for boys. If you haven't been spending much time around babies recently, you may be surprised to learn that Riley is the most popular girls' name starting with R and also the Number 1 Irish name for girls in the US.

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.

Eden is an attractive, serene name with obvious intimations of Paradise, one of several place names drawn from the Bible by the Puritans in the 17th century.

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.

Fairy-tale memories of Sleeping Beauty inspire some parents—such as Rachel Bilson and Hayden Christensen—to call their daughters Briar Rose.

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.

Unlike Amber, which is in decline, this name still has a bit of a glow left — though confusions between the two will inevitably arise.
