The Castle Mill remained in Heinrich von Stockheim's heirs’ ownership until Kurt von Lützow and his son Ernst Christoph sold the "Stockheimische Wohnhaus" on 28 September 1677 along with appurtenances, holdings and revenue in Heidesheim, Framersheim, Gau-Bickelheim and Selzen (near Alzey) to Elector of Mainz Damian Hartard von der Leyen (d. 1678) and his heirs. Thereafter the property found itself owned by the Lords – beginning in 1711 Counts – of the Leyen, who administered their scattered holdings on the Moselle and the Rhine first from Koblenz and beginning in 1773 from Blieskastel (Saarpfalz) and gave out the Castle Mill on a heritable lease. Information about the time from 1677 to 1793 is promised by the contents of the archives of the (beginning in 1806) Princes of the Leyen, which in 1995 ended up in the Rhineland-Palatinate Main State Archive in Koblenz, but hitherto not much of this information has been forthcoming.
