Oswald

Oswald is an Old English and Old High German name composed of the elements os, meaning "god," and weald, meaning "power" or "rule," giving the overall sense of "divine power." The name was borne by Saint Oswald of Northumbria, a seventh-century Anglo-Saxon king and Christian martyr whose veneration helped spread the name throughout medieval England and into Germany. It remained in steady use through the Middle Ages before declining and experiencing modest revivals in the nineteenth century. Related forms include the Old Norse Ásvaldr and the Latinized Oswaldus, and it shares its first element with names such as Oswin and Osbert.
