Abbey of Saint Gall
The toponym "Eschbach" is a composed word consisting of the German words "Esche" (ash tree) and "Bach" (brook). However, the settlement is first mentioned in a document of the Abbey of Saint Gall of 807 under the name "Ascabah". "Asca" is Old High German meaning burnt "ash". On the other hand, the Geographical Dictionary of the Archive of Baden-Württemberg relates it to "aspa" (Old High German for "aspen").
