Is it Marlo, Marlow, or Marlowe? Suddenly they all seem very much in the air, in tune with rhyming cousins Harlow and Arlo.

Natalie—a Franco-Russian name—became Americanized years ago and is one of those surprising names that's always ranked among the girls' Top 1000 names 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.

Sloane is a sleek, sophisticated surname name that has gradually morphed over to the girls' side. Sloane is definitely a name that's going to continue to rise. Spelled without the final "e," Sloan joined Sloane in the Top 1000 for the first time in 2011.
