Diedrich

Diedrich is a Low German form of the name Dietrich, derived from the Old High German elements theud, meaning people or folk, and rīhhi, meaning ruler or power. The name is thus closely related to the broader Germanic name Theodoric, which was borne by the famous Ostrogothic king Theodoric the Great in the late fifth and early sixth centuries. Diedrich remains associated with northern German-speaking regions and shares its ancestry with Dutch Diederik and English Derek.
