Theobald

Means "bold people", derived from the Old German elements theod meaning "people" (Old High German diota, Old Frankish þeoda) and bald meaning "bold, brave". It was borne by a 6th-century Frankish king of Austrasia. The Normans brought the name to England, where it joined an existing Old English cognate. The medieval forms Tibald and Tebald were commonly Latinized as Theobaldus. It was rare by the 20th century.
