The archives of the Princes of the Leyen are yielding as little about the upheavals of the French Revolution and the Napoleonic Wars as about the time before this, and as for the decades that followed, no information is forthcoming about the Castle Mill. Although the cadastral plans from 1812 and 1841 to 1843 offer a scale drawing of the property, they say nothing about the castle's owners. The municipality's cadastral register lays down in writing on 26 July 1865 that the estate owners were August Krebs (d. 1905?) and his wife Elisabeth, "née" Schmahl, who had acquired the Castle Mill by way of trade – from whom it is unknown.
