Sources and guide to preserved records

References [1]–[56] and their image-provenance notes are preserved in Part II, especially its original pages 49–53. The additional newspaper, death-register and archive leads are preserved in Part III. This narrative uses the bracketed numbering of the earlier booklet where applicable; newer correspondence is named in the text. A source cited as a lead remains a lead until the original is inspected. • 31 October 1946: signed mayoral reply on NBS affiliation and family (Part II, archival plates). • 1954–1973: OGS identity, death, burial and grave-maintenance correspondence (Part II, plates and source register). • 15 and 18 May 1945: Elburger Courant notices and funeral coverage (Parts II–III). • 27 February 1970: retrospective Elburger Courant account (Parts II–III). • 8 May 1971: Elburger Courant item identified by Willem van Norel, original text still to be reviewed. • October 2026: correspondence with Willem van Norel, The National Archives and Stichting Doetinchem Herdenkt. Preservation note: the two complete earlier PDFs follow as documentary sections. They retain their original pagination, historical images, source notes and any unresolved interpretations. The revised Part I should be used for the latest integrated account.
