Another ancient archaeological find has been a Roman cremation site from the 1st century AD, found some 200 to 250 m southeast of the parish church in the cadastral area called “Rosenberg”.

Müllenbach's first unequivocal documentary mention came on 1 May 1333 when Aleidis, Heinrich von Molinbach's widow, sold her inheritance from her mother in Düngenheim for 100 Denare to the Stuben Monastery.

On 11 December 1357, Sir Konrad von Brohl, a knight, was enfeoffed by Rupert I, Elector Palatine with the village of Mollenbach, along with the Hause Kaldenbrunnen (Kalenborn), Haurode (Hauroth) and Gut Rode (later Gerhardsroth) in the Mastbrecht (Masburg) court district.

It is known that witch-hunts in the area reached a height between 1500 and 1650, and although there is no record of such things happening in Müllenbach, it is reasonable to assume that the village was caught up in this madness.

In 1695, records from the Mayen-Monreal financial administration mention for the first time slate mining in Müllenbach as a business subject to levies (called the Deckleyenzehnt, or roughly “roofing stone tithe”).

In 1724, as the result of a new enfeoffment, H. Arendt from Müllenbach was assigned the slate mine in Hochpochten and was granted three tax-free years to offset the trouble and cost of putting the site in order.

In 1725, the church books mentioned the Kaulenmühle (mill) for the first time when Nikolaus May from Müllenbach married his first wife Elisabeth Niederelz on 16 October 1725 in Masburg.

He held the post until 1786, but the records also mention another curate, Johann Peter Rhein, born in Metternich (today a Stadtteil of Koblenz), in the years 1771 and 1772.

At this, Father Gilles had apparently become physically abusive and driven Michels out of the house, swearing at him by calling him such unchurchmanlike things as Hundspfott (“dog dropping”) and Scheisskerl (something akin to “bastard” in the colloquial sense, but literally meaning “shit-fellow”).

In 1785, a Visitation protocol from the parish of Masburg mentions that Müllenbach freeman Niclas Stoll was a Sendschöffe (a kind of judicial representative), and furthermore that he had held this post already for six years.

In 1791, records at Springiersbach Monastery showed that a parcel of cropland of 1.29 ha was auctioned to a farmer from Müllenbach named M. Steffen.

The first few years of the 19th century brought the village two new curates, Peter Joseph Pauli in 1802, born in Maring and serving until 1805, and replacing him, Philipp Reichards.

In 1842, Landrat (District Chairman) Schönberger sent Mayor Driesch of Kaisersesch a letter asking him to explain law-flouting incidents that had been happening in Müllenbach after abuse of alcohol – notably one that had seen a young man stabbed several times.

Locally, the bailiff Hartrath found his activities thwarted by Müllenbach inhabitants, and indeed he was hounded out of the village under “a rain of stones”.

He had wanted to gather monies that were due the authorities, but he, too, was driven from the village, this time in the face of swearing and cursing, and under a rain of, not stones, but rather rotten fruit.

Once the bailiff had reported to his employer what had happened, the monarchical leadership in Berlin sent specially an infantry company of 280 men to Müllenbach to restore order.

This same year also brought the Kulturkampf, which saw Father Pörzgen, the parish priest in Masburg, thrown out of his job and forbidden to practise spiritual guidance.

In 1880, in the cadastral area called “Wolfsburg” near Leienkaul (roughly 2 km from Müllenbach), the last wolf in the eastern Eifel was shot.

One was released early, and the three ringleaders, Peter Krämer I, Reuter and Lefev, were, owing to mitigating circumstances, sentenced to prison terms ranging from 9 to 10 years.

Amid the general fear that the Great War would last longer than first expected, older youth were being readied for military service.

By 1918, there was no dearth of soldiers who did not want to go back to their posts after taking leave, and about ten to fifteen deserters lurked in the Müllenbach area, stealing chickens, livestock, food and even money.

On 21 March of that year, with the opening of the Reichstag, the National Socialists’ seizure of power was celebrated in Müllenbach with a torchlight parade through the village.

Not long thereafter, shoppers were being harassed and blocked from entering the Mayer butcher shop at Dorfstraße 116 in Müllenbach – a Jewish-owned business.

On 30 April 1942, Müllenbach's Jewish inhabitants (Emanuel, Johanna and Julius Mayer and a foster-child named Heinrich) were deported to a death camp in Poland.

[4] In late February 1952, work began on a munitions camp in Hochpochten, thus bringing jobs to those in need of a livelihood, if only for a matter of months.

On 4 December 1960, a hurricane raged over the area knocking down telegraph poles, blowing windows in, lifting roofs off and littering roads and railways with fallen trees.

In October 1994, there was an uproar when, in a marquee full of people, a 30-year-old man from neighbouring Kaisersesch chose the occasion of the playing of the National Anthem to give the Nazi salute.

By the end of the year, AJE Consulting, a company based in Roes, had brought wireless Internet service to the municipality.

This same year, Andreas Klotz became mayor of Müllenbach, and for the first time, the local school had no beginners at all, a result of the shrinking birthrate.

The municipal election held on 7 June 2009 yielded the following results:[7] Müllenbach's mayor is Andreas Klotz, and his deputies are Dirk Barbye and Dieter Laux.
