Emerson is a dignified, somewhat serious name associated with transcendental thinker Ralph Waldo Emerson. Much more popular now for girls since Desperate Housewife Teri Hatcher used it for her daughter, it is definitely still a viable boys name.

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.
