 After Gerlach I of Veldenz had founded the County of Veldenz in 1136 and been raised to "Schutzvogt" (roughly, “protector”) over the "Remigiusland", the Counts of Veldenz were also deemed to be the local lords.In 1320, Welchweiler had its first documentary mention as "Weldichwilre".According to the document itself, Archbishop Baldwin of Trier received three Rhinegravial "Burgmannen", the brothers Heinrich, Gerhard and Simon from Heppenheim (today an outlying centre of Worms), as armed men in his service, enfeoffing them with, among other things, a piece of land near Welchweiler.
