 The family Straubenhardt became extinct in 1442 and the sovereignty of the properties slowly moved towards Württemberg and Baden.It is suspected that the nobles of Straubenhardt initiated the foundation of the villages Conweiler, Feldrennach, Langenalb, Schwann as well as Arnbach, Dennach, Dobel, Neusatz and Rotensol".The discovery of a relief of the hunting goddess Diana, found in the wall of the rectory of Ottenhausen, indicates an early Roman settlement in this area.
