Three John Paul Jones letters to Thomas Jefferson (that have been published in the Jefferson Papers); one Benjamin Franklin letter to John Langdon (25 October 1788) concerning abolition; and thirty-two letters(1826-1858) of Jonathan Knight to Nathan, Ann, and Abel Whealdon of Harrison and Morgan Counties, Ohio. There are also two Carey sketches among these papers, one of Knight, the other of a friend of Will S. Porter (O. Henry).
Jonathan Knight was a prominent civil engineer associated with the construction of the National Road and the Baltimore and Ohio Railroad and from 1855 to 1857 a Whig member of Congress.
