[3] Clockwise from the north, Kellenbach's neighbours are the municipalities of Königsau, Henau, Schwarzerden, Weitersborn, Simmertal, Brauweiler, Heinzenberg, Hennweiler and Schlierschied.

About 1750, the knightly estate, with and area of 651 Morgen[7] (roughly 2 600 m2), was sold to the former Amtmann at the neighbouring castle, Wartenstein, in the Hahnenbach valley, Franz Philipp Renauld.

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.

[8] Under Prussian rule beginning in 1816, Kellenbach was assigned to the Bürgermeisterei (“Mayoralty”) of Gemünden (which as of 1927 became an Amt) and thereby to the Simmern district.

On 7 June 1969, in the course of the implementation of the State Law of 12 November 1968, it was, together with Königsau, Bruschied, Schneppenbach and Schwarzerden, assigned to the Bad Kreuznach district and the Verbandsgemeinde of Kirn-Land.

[9][10] On 9 January 1971, a great fire destroyed part of a caravan factory, a branch plant of Wilk-Caravaning GmbH, on Kellenbach's northern outskirts.

[11] On 22 January 1985, an icejam led to flooding of Kellenbach's main street, resulting in great damage to the buildings there.

After a three-week cold spell, the river in the village core and all the way upstream towards Simmertal was thickly frozen over, but then a thaw drove huge ice floes downstream.

Disagreements between various authorities as to who was responsible for dealing with the situation prevented explosives from being used to break the icejam, as residents had demanded, and as had at times also been done before.

After livestock had been evacuated and sandbags had been laid on, the icejam finally broke up by itself shortly before midnight, once again allowing the water to flow freely.

[18] Listed here are Kellenbach's mayors since 1850: The German blazon reads: In geteiltem Schild oben in Rot ein schreitender, herschauender, silberner Leopard, unten in Silber über gewelltem Schildfuß drei grüne Spitzen.

After consent by the state archive, the Ministry of the Interior in Mainz granted approval for Kellenbach to bear its own arms on 20 January 1971.

[21] The following are listed buildings or sites in Rhineland-Palatinate’s Directory of Cultural Monuments:[22] Saint Hildegard's, also described as a chapel, is a branch church of the Catholic parish of Seesbach.

Research by the pastor H. Gramm in the 1920s yielded the knowledge that the church had originally been consecrated to Saint Vitus (or St. Veit in German).

Since January 1977, the old schoolhouse has been used as a kindergarten, which on the occasion of its thirtieth anniversary in 2007 was dubbed Haus der kleinen Freunde (“The Little Friends’ House”).
