 It could be that the area west of the Herrmannsberg was only settled in early Frankish times.From the time of its founding, Welchweiler lay within the so-called "Remigiusland", whose borders are laid out precisely in a 1355 "Weistum" (a "Weistum" – cognate with English "wisdom" – was a legal pronouncement issued by men learned in law in the Middle Ages and early modern times).The village was originally independent of the Archbishopric of Reims and the Abbey of Saint-Remi in Reims.
