John Winston Spencer Churchill, 7th duke of Marlborough (1822-83), son of the 6th duke, was a Conservative politician. As marquess of Blandford he was M.P. for Woodstock 1844-45, 1847-57. He was Lord Steward of the Household 1866-67, Lord President of the Council in Disraeli's government 1867-68. Disraeli offered him the Viceroyalty of Ireland in 1874, which he declined, but he accepted the post in succession to the duke of Abercorn in 1876, and was Lord Lieutenant (Viceroy) until Lord Beaconsfield's ministry resigned in 1880. He was the father of Lord Randolph Churchill (see Add. 9248). The papers were purchased by the Library in 1994.
