Beginning in 1707, the landlord was the Margrave of Baden as heir to the Sponheim holdings. About 1750, the knightly estate, with and area of 651 "Morgen" (roughly 2 600 m2), was sold to the former "Amtmann" at the neighbouring castle, Wartenstein, in the Hahnenbach valley, Franz Philipp Renauld. In the 18th century the village belonged to the Badish "Oberamt" of Kirchberg. After French Revolutionary troops had overrun and occupied the German lands on the Rhine’s left bank, Kellenbach, along with all the lands that the French had occupied, was absorbed into the French state. In 1794, the region was administratively reorganized according to the French Revolutionary model, putting Kellenbach in the "Mairie" (“Mayoralty”) of Kirn and the Arrondissement of Simmern. About 1800, there were 40 houses in Kellenbach, 4 of which had been expanded by having upper floors built onto them. The last Lord of Kellenbach died in 1798.
