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.

Rosalie hit its apex in 1938 and then slid straight downhill until it fell off the U.S. Top 1000 completely in the 1980s, only to spring back to life in 2009 as the name of a character in the Twilight series. The beautiful vampire Rosalie Hale has breathed fresh life back into this mid-century name, and the fact that the character is both sympathetic and relatively minor means Rosalie has the chance to thrive again as a baby name without feeling unduly tied to Twilight.

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.

Though Loretta has long ago lost its Latin flair, fashionable Sarah Jessica Parker's choice of it as the middle name of one of her twin daughters freshens it up a bit. It's one of several such names, like Anita and Rita that we can envision making a comeback.
