Baby Girl

Newly fashioned but familiar and with an on trend, unisex feel, Addison seems like the perfect solution for anyone who can’t decide between Madison, Adeline, and Alison.

Amelia is one of the hottest girls' names, a successor to the megapopular Emma and Emily. Amelia, which spent several years at Number 1 in England, is now comfortably ensconced in the US Top 10.

The most enduringly popular hero of Irish myth was Finn McCool, whose name is one of the coolest ever. When used for the female protagonist of How to Make an American Quilt, Finn established its hipness for girls as well.

Lilly may contain one L too many for some people, though this secondary spelling of a name that's become wildly popular is still a popular choice. And the Lilly spelling does feel a bit less wispy, a bit more like a name as opposed to a mere flower, than the slender and delicate Lily. Lilly suggests the long-form Lillian, but it doesn't need to be an abbreviation for anything; Lilly can stand on its own.

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.

Sophia, which was the Number 1 girls' name in the US from 2011 to 2013, is among the top girl names in the Western World, with a sensuous sound and high-minded meaning. A real winner, Sophia reached the top of the charts without losing any—okay, much—of its sophisticated beauty.
