Isaiah

From the experts:

Isaiah, like brethren Isaac and Elijah, is a once neglected biblical name now firmly back in favor, already surpassing such long-popular Old Testament stalwarts as Aaron and Adam. Isaiah now ranks at Number 47.

The biblical Isaiah, son of Amos, was the most important of the major prophets, with an Old Testament book named for him. He prophesized that the Children of Israel would be exiled from their homeland but that God would bring the back.

Isaiah has been a star player on the contemporary athletic field, with several prominent basketball and football player namesakes, in addition to a memorable character on Little House on the Prairie, and Grey's Anatomy actor Isaiah Washington.

Beyond that, two sports figures have named their sons Isaiah: Allen Iverson and Tim (and wife Elisabeth) Hasselbeck. Basketball superstar Isiah Thomas helped popularize that streamlined spelling of the name.
