 Later forms of the name that the village bore were, among others, "Nanßweiler" (1504) and "Nantzweiler" (1600).Even in the field of church history, a distinction must be drawn between the villages either side of the Glan.Dietschweiler and Nanzweiler on the left bank belonged from the Early Middle Ages onwards to the Church of Glan-Münchweiler, which was consecrated to Saint Pirmin and tended all churches in the Münchweiler Tal (dale).
