Composed between 1656 and 1671, collected by an amanuensis.

Material distinct from Enoch Powell's own papers as it has a different provenance (it was not maintained with Powell's own archive) and cannot be considered as having been generated by the same processes as Powell's papers.

The collection chiefly compiles Lady Onslow's personal letters written to her parents and sister "Jim" from her travels in Churchill's service. They provide first hand evidence of her experiences and include lively recollections of Churchill, descriptions of her work and colleagues, and descriptions of journeys, accommodation and surroundings. The letters are supplemented by a small number of photographs and other mementos.

'Orationes in Doctorum Theologiae', 70 folios. Nine orations on various subjects relating to the University of Cambridge, made at creations of Doctors of Divinity, 1758-1770.
