Jagger, made famous as the surname of Rolling Stone Mick, gets an entry in the girls' column thanks to Ashlee Simpson and Evan Ross, who chose it for their daughter. For either gender, this name rocks...but a bit jaggedly. Currently, there are nearly 20 times as many baby boys than girls are given the name Jagger. That balance may shift, making Jagger a more truly gender neutral name.

A popular Irish name virtually unknown here, but one that feels like it could follow in the footsteps of Siobhan and Saoirse. It's pronounced SOR-ka, but with a little hiccup between the 'r' and the 'c' that's difficult for non-Gaelic speakers to reproduce. Spelled (and pronounced) Sorsha, she is a major character in the movie Willow.

Hot name best used as a middle, as Paula Patton and Robin Thicke did for their son Julian in 2010.

From the first time we saw the name Saskia attached to a portrait of Rembrandt's wife (her full name was Saakje van Uylenburgh, but she was always called Saskia), we have found it utterly charming and wondered why it hasn't attracted more fans In this country--she's appreciated by the Brits, who have moved her to Number 392. Saskia is one of those names that's been used in Europe since the Middle Ages, but has never crossed the ocean.
