This correspondence is principally concerned with business between Pershouse and his brother James in England, with comments on conditions and events in the United States, including anti-British feeling, Thomas Paine's return to America, Jefferson's administration, and immigration. The papers include Pershouse's journal (1800-1838), which includes accounts of travels in England, France, and the United States, letterbooks (1836-1862) of Henry Pershouse, nephew of John, chiefly on business matters, and two volumes of Pershouse genealogical data, compiled by B.M. Pershouse Bayley (1899).

In addition to family and business correspondence, the Charles Nicoll Bancker Family Papers contains various documents, such as a furniture inventory volume (30pp.); a Daybook, 1795-1800 (120pp.); and a very interesting journal (unidentified, but by one of the Banckers, and filed under "Description of a trip..."), from New York to Albany and back, between July 20-Aug. 15, 1793 (1 vol., 31 pp.). It contains detailed observations of the Hudson River and the towns along the way. Bancker was involved in business and trade prior to 1826, and in insurance after that date, so there is material relating to those topics in this collection. He owned a substantial library of the period, which was used by Charles Wilkes's Expedition after 1837 (see Reynell Coates to Bancker). This library, along with Bancker's notable scientific instrument collection, was sold after his death and there are published auction catalogues in the collection. There is much family correspondence from: Anne E. Bancker, Charles Gerard Bancker, Evert Bancker, Sarah U. Bancker, Violetta Bancker Talbot, Elizabeth Bancker Teackle, and John Teackle.
