This Welsh nature name that can be pronounced exactly like the male Ira. Or, to avoid confusion, you could just name her Snow.

Striking name of a legendary princess and a Welsh river that feels both moody and modern.

A beautiful modern Cornish nature name that is rapidly picking up steam in the States: even spawning variant spellings like Elowyn and Elowynn. In its native region, it wasn't widely used as a name before the twentieth century, when the Cornish language was revived.

Lost in limbo for decades and decades, Elsa now stands a good chance of following along in the progression from Emma to Ella to Etta, thanks to the ice queen heroine who "Let It Go" in the wildly popular Disney movie Frozen.

Still, the status of the classic books means Eyre deserves to stand proudly among English baby names.

This attractive Scottish surname choice, has a certain amount of glamour thanks to feisty British-born red-haired forties Academy Award winner Greer Garson, who was born Eileen Evelyn Greer Garson--Greer was her Irish mother's maiden name). Greer was chosen much more recently by Kelsey Grammer for his daughter and by Brooke Shields in the Grier form. As a surname, it's associated with feminist writer/activist Germaine Greer.

The rise of the the various Isabel names may give a boost to this variation, which has a sunny, springtime feel.
