The next tithe lord after Daun was Manderscheid, for on 10 October 1493, Johann, Burgrave of Manderscheid and Count of Blankenheim, and his wife, Margret von der Mark gave each of their daughters Anna and Irmgard at the Marienberg Convent 20 Malter of grain from their tithes in Illerich.
Towards the end of the 18th century, the tithes from Illerich were the subject of disagreement between the Countess of Sternberg and the Abbot of Brauweiler, leading to a rather lengthy court case between 1783 and 1787 [REF].
