Early Origins of the Dehn family

The surname Dehn was first found in Bavaria, where the name was closely identified in early medieval times with the feudal society which would become prominent throughout European history. The name would later emerge as a noble family with great influence, having many distinguished branches, and become noted for its involvement in social, economic and political affairs. Like many surnames, the name Dehn began as a personal name and was later adopted as a surname. It is a shortened form of the Germanic personal name Deinhard, which is made up of the words "degen," meaning "warrior or hero" and "hard," meaning "brave or strong."
