From german wikipedia, translated via google:
"The district Palenberg is first mentioned in a document dated January 20, 867 on an exchange of goods between a vassal of Jülich Count Matfridt called Otbert and the Frankish King Lothar II in writing. Around the year 1000, the place probably belonged to the rule Geilenkirchen, which came in the 12th century in the possession of the Lords of Heinsberg. With the rule Heinsberg Palenberg finally came to the Duchy of Jülich and became part of the Jülich office Geilenkirchen.
The first mention of Übach took place in 1172 with mention of a nobleman of the same name as Ministerial of the Abbey of Thorn on the Meuse. At least since that time, the abbey has exercised dominion over the place, but probably earlier."
