Avery is a hugely popular name in the US, especially for girls. But while nearly four times as many girls as boys are named Avery today Avery's popularity is starting to soften for girls while it continues to strengthen for boys.

The superpopularity of Emily and Emma has recently boosted the unisex Emery, especially since it became a celebrity baby name when it was chosen by Angie Harmon and Jason Sehorn.

The combination of Emily and Emma's popularity -- and the fact that Desperate Housewives star Teri Hatcher's daughter is named Emerson -- have put this formerly strictly boys’ name, embodying the gravitas of Ralph Waldo Emerson, in the limelight for girls.

Sawyer is one of the top unisex names, used for their daughters by such parents as Sara Gilbert, co-host of The Talk and former actress on Roseanne, currently on The Conners.
