If you like Amy

Amy was a 1970s favorite, and French spelling Aimee peaked in the same decade.

Ella is a sweet, simple name that owes much of its current popularity to the popularity of other names, from Emma to Bella to Emily to Ellie.

Combine the charming heroine of the movie Legally Blonde with supermodel Elle Macpherson and the trend toward all names beginning with "el"—Ellie, Ella, Eleanor—and you have one hit name.

Isabella has been a Top 10 name for girls in the US for two decades now. The Latinate form of Isabel, a variation of Elizabeth which originally derived from the Hebrew name Elisheba, Isabella reigned as Number 1 in 2009 and 2010.

Isabelle is the French variation of Isabel, which emerged in the Middle ages as an Occitan form of Elizabeth. Medieval queens Isabella of Angoulême and Isabella of France helped popularize the name in the United Kingdom. Isobel is the Scottish version, Isabella the Italian, and Izabel is used in Brazil.

The longer Isabella stays in the Top 10—and it's been there for more than a decade—the more we hear the nickname Izzy (especially if we watch Grey's Anatomy). it's just a matter of time before it stands on its own, as it has as a first name for the daughter of Eddie Murphy and Paige Butcher.
