The archives from Dunham Massey Hall contain very few papers of the 7th Earl of Stamford or of Katherine, Countess of Stamford & Warrington. In 1855 the Earl quit Dunham Massey, reputedly because his marriage to Katherine Cocks met with disapproval from the local community. For the rest of his life he resided at the other Grey family residences, Enville Hall and Bradgate Park, where he would have kept his personal papers. The few items that have survived either pre-date the move, or have found their way back to Dunham, probably during the twentieth century. These are: two school exercise books, 1844 (EGR4/5/1-2); a petition to Lord Stamford from the Altrincham and Bowdon Literary Institution, 1851 (EGR4/5/3); two bundles of miscellaneous papers and tradesmen's bills, 1851-7 (EGR4/5/4-5); letters from Edward, Prince of Wales, to the 7th Earl and to his widow, Katherine, 1882-3 (EGR4/5/6-9); and an address to the Countess of Stamford & Warrington from tenants on the Leicestershire estate, 1893 (EGR4/5/10).
The papers of George Harry Grey (1765-1845), 6th Earl of Stamford, contain three letters exchanged between him and George Harry Grey (1827-83), 1842-3 (EGR4/2/11/13-15). There is a reference to the 7th Earl of Stamford's childlessness in a letter from Rev Harry Grey among the papers of various members of the Grey family (EGR4/10/22/9). Within the subfonds EGR11, Papers from Dunham Massey Hall relating to the Cheshire and Lancashire Estates, there are accounts for donations by the 7th Earl of Stamford to Bowdon parish church and the Chester Infirmary, 1859-62 (EGR11/3/4/5-9, EGR11/3/5/71 & EGR11/3/5/92). There is a further account for a donation by the 7th Earl to the Chester Infirmary among the miscellaneous papers from Dunham Massey Hall, 1860 (EGR13/26/7).
