Original manuscripts, mainly 1800-1840. In Brant's correspondence, 1800-1806, are his drafts and retained copies of letters to William Claus, Alexander Grant, Robert Kerr, Peter Russell, D.W. Smith, and a few others. Among those writing to Brant were Israel Chapin (1800), John Chew (1802), Claus (1800-1804), J. Humphreys (1803), Hannah Jarvis (1803), and N. Le Favre (1801). Although land problems constitute the major topic in the correspondence, letters exchanged by Brant and Claus (1800-1801), proceedings (1802) of a council held by Mohawk women with Brant and other chiefs, and Claus's speech at a council in 1804 all allude to or discuss problems and misfortunes caused by alcoholism among the Indians. Brant's name appears on a list of temporary appointees and pensioners of the Indian Department of Upper Canada in 1802-1803 signed by John Johnson and Peter Hunter. Very few letters and notes relate to the settlement of Brant's estate.

Seemingly unrelated to Brant is a letter (1813) of Alexander Parker to Thomas Posey concerning a military incident involving Anthony Wayne in 1782. A business receipt (1822) was signed by mark of Red Jacket. Other papers after 1815 consist of family letters and legal records by and about Mrs. Margaret Farley, Mrs. Mary Margaret Kerr Clark, and William Johnson Kerr, descendants of Sir William Johnson and Molly Brant. Undated drafts of letters and speeches to Indian councils, many by Brant, fill the final segment of this volume.
