The earliest verifiable documentary mention, from 1246, is to be found in a not very accessible information book given to the Benedictine and Cistercian orders. In another document from 23 June 1336, in which Niedereisenbach is named as "INFERIORI YSENBACH" ("nieder" – cognate with the English word "nether" – in German and "inferior" in Latin both mean "lower"), Werner, the archpriest of Kusel, witnessed the building of the chapel consecrated to Saint Valentine at Eisenbach. In 1358, Clas von Kellenbach pledged the village of Eisenbach, which he held in fief, and the mill to Count Heinrich of Veldenz for the sum of 180 pounds in hellers. From the 13th century onwards, until French Revolutionary troops marched in during the French Revolution, Niedereisenbach always belonged to the Barons of Kellenbach, who as early as 1289 donated the "Hirsauer Kirche" to Saint Mary's Monastery of Offenbach.
