Claire, luminous, simple, and strong, is one of those special names that is familiar yet distinctive, feminine but not frilly, combining historical depth with a modern edge.

Ada is one of the classic baby names for girls that is suddenly super stylish again. A favorite at the end of the nineteenth century, Ada is an alternative to the over-popular Ava. Ada is also part of the trend toward simple, old-fashioned names beginning with a vowel, like Ivy and Ella.

Grace, a simple and pure virtue name which originally referred to divine grace, is a fashionable classic. In the early 2000s, it seemed headed for the Top 10 but pulled back from the upward trajectory, which you may consider a very good thing.
