At the end of World War II, the libraries of the German Army's Military Geology Unit (Wehrgeologenstellen) and the German Patent Office (Reichspatentamt) were removed from Berlin and secretly stored in the deep Wintershall potash mine in Heringen.
The manor was handed down via lines of the interconnected Wintershull/Wintershall, Bassett, Unwyn, Windsor, Wolley and Wroth family from Thurstan le Dispenser at the time of the Testa de Nevill into ultimately the major landholdings of the Earls Onslow in the 18th century, historically the Earl of Surrey who held it until the early 20th century.
