The biblical Ezra was an Old Testament prophet who led the Isrealites back to Jerusalem and author of the Book of Ezra. The name is a good alternative for parents looking for a biblical name that's not David, Samuel, or John. While it's at its peak in popularity right now, it's still uncommon enough that you won't be running into a dozen other Ezras on the schooyard.
Poet Ezra Pound, Writer Ezra Jack Keats, Actor Ezra Miller
