Ella

Following in the path of Emma and Isabella/Bella, Ella has been shooting up the charts since the millennium: it rose from Number 265 in 2000 to a high of Number 12 this past year.

Ella has long been a fave of the glitterati -- including the John Travoltas, the Warren Beattys, Ben Stiller, Eric Clapton, Jeff Gordon, Ioan Gruffudd, Alex Rodriguez, and Mark Wahlberg.

Iconic singer Ella Fitzgerald adds a jazzy edge. One other appeal of Ella: It sounds both vintage and modern at the same time. Although it hadn't been used much for a few generation and so sounds fresh, there are an awful lot of little girls named Ella running around -- along with those called Ellie and Bella. So while it has much to recommend it, don't say we didn't warn you about Ella Enchanted's popularity.

And her popularity isn't limited to the US: Ella is also in the Top 10 in England and Wales, Ireland, Australia, and Sweden.
