Zebulon Montgomery Pike (1779-1813) was an explorer and soldier, most often remembered two exploratory trips to the newly acquired Louisiana territory. The first of these trips was to the source of the Mississippi River in 1805; the second was to explore the headwaters of the Arkansas and Red Rivers in 1806. Because General James Wilkinson was responsible for organizing Pike's two expeditions, when the conspiracy charges again Aaron Burr implicated Wilkinson, suspicion was, for a short time, also focused on Pike. Pike worked his way up the ranks of the United States Army, becoming a brigadier-general during the War of 1812. He was killed in the Battle of York in Upper Canada (now Toronto) in 1813.

A merchant and member of the Society of Friends, Pim Nevins (1756-1833) lived most of his life in the English midlands. Recorded in Pigot's Directory of 1834 as a member of the gentry resident in Hunslet Lane, Leeds, Nevins was a woollen cloth manufacturer, finisher, and merchant whose operations were located at Larchfield Mill, near Huddersfield. During a voyage to visit Friends' meetings in the United States in 1802-1803, Pim Nevins kept a journal to record his thoughts and experiences. In presenting a copy of his diary to his children, he wrote: "some parts [of the diary] wch. being by way of memorandum to assist my memory will of course be no ways interesting to you; other parts being fill'd with the effusions of my own thoughts, will I fear be dry to you unless your minds should in some measure be dip'd into the like state with mine when influencing my pen; some other parts may entertain you." The journal includes a mixture of description of the cities, towns and landscape through which Nevins passed and accounts of his visits with Friends in New York city, Philadelphia, Wilmington, Baltimore, Washington, Alexandria, Bethlehem, Pa., Easton, Pa., the Pocono Mountains, northern New Jersey, New Brunswick, N.J., and Trenton, N.J.
