The collection consists chiefly of eighteenth- and nineteenth-century material. The earlier material concerns the settlement of affairs after the deaths of Rev. Randolph Marriott in 1782, and of Rev. Robert Deane in 1799, whose brother-in-law, Randolph Marriott (1736-1807), was executor. Correspondence of Marriott family members, chiefly Randolph Marriott and his wife Elizabeth, contains details of both personal and financial matters. These include attempts to clear the debts of Randolph and Elizabeth's son-in-law, Captain Yeoman, family news, business, and war in India (1789-1803).
A small group of papers concerns goods, including groceries and silverware, sent by Mrs Marriott to her children in India. The correspondence between women in the family includes news of family and social affairs. There are also papers relating to family wills and settlements, and a number of account books and household inventories.
