From the Old English elements os
"god" and mund
"protector". During the Anglo-Saxon period a Norse cognate Ásmundr
was also used in England, and another version was imported by the Normans
Osmund was an 11th-century Norman nobleman who became an English bishop. Though it eventually became rare, it was revived in the 19th century, in part from a surname that was derived from the given name.
