During the transfer of the House of Ehreshoven to the cooperative of the Rhenish knightly nobility in 1920/24, the archive of the Counts of Nesselrode was brought to Velen and from there it was loaned to the State Archives. It was purchased in 1954. More than half of the files (numbers 1-600 and the group "Landesarchiv", see Findbuch 110.22.03) were on the barge "Main 68", which sank in March 1945 in the Mittellandkanal (cf. F.W. Oediger, Das Staatsarchiv Düsseldorf und seine Bestände Bd. 1, p. 43). So far not all pieces could be restored. Retroconversion of the analogue find book: Rheinisches GeschichtsKontor Klein Oesl Opheys GbR, Alfter, 2010 - Final Control and Revision: Staatsarchivamtmann Jörg Franzkowiak, November / December 2012.
