- John Clarkson (1764-1828) was an English abolitionist, agent for the Sierra Leone Company, and lieutenant in the British Royal Navy. The collection consists of Clarkson's manuscripts, written in journal form, of his involvement with the settlement of free African-American loyalists from Nova Scotia to Sierra Leone, Africa. The loyalists had been evacuated from New York when the British pulled out at the end of the Revolutionary War and initially settled in Nova Scotia. Volume 1, entitled "Clarkson's Mission to America," covers August 6, 1791-March 18, 1792 as Clarkson arranged for the transportation of the settlers; it provides a detailed account of his activities in Nova Scotia, persons he met there, and the problems fitting out the ships. Volume 2, entitled "Clarksons Mission to Africa," covers March 19, 1792-August 4, 1792. Clarkson's account of the founding and first months of Free Town, Sierra Leone gives numerous details of the difficulties met, relations with the native population, attitudes of the Nova Scotia settlers, and supplies.
- Joseph Goodwin was a plantation manager in Cuba originally from Hudson, N.Y. This diary was presumably kept by Goodwin, although it may have been kept by his brother. After leaving home in Hudson, N.Y., Goodwin worked for Gen. George De Wolf, first in Bristol, Rhode Island for a few months and then on De Wolf's plantations near Matanzas, Cuba as a manager or overseer. The plantations grew mainly coffee, although other crops are mentioned. The crops were worked by enslaved labor. The diary entries are mainly routine and record weather, plantation activities, people met, and local news. They often mention George and William De Wolf. While in Cuba, Goodwin stayed first at the home of John Line and later at the plantations Buena Esperanza and Arca de Noe. Some pages of the diary are missing.
- James F. Brown (1793-1868) was the gardener of the Verplanck family at Mount Gulian, Fishkill, New York. Brown had been enslaved in Maryland before running away, and the Verplancks purchased his time after he was found by his enslaver. The collection consists of 8 diaries, 1829-1866, during which time Brown was gardener for the Verplanck family; 1 receipt book, 1832-1857, recording some personal and household expenses, although most entries are unspecified; and 1 memorandum book, 1827-1843. Entries in the diaries are brief, with little elaboration, and pertain to such matters as the weather, local deaths, his gardening activities, the passage of boats on the Hudson, etc. The diaries are not entirely chronological, as in several instances the entries for a year have been copied into a later volume.
