Campbell (1768-1814), Presbyterian minister, author, and antiquarian in Kentucky and Ohio; obituaries for William Goforth (1731-circa 1807), Ohio legislator and judge, and Robert H. Smith (d. 1812), physician in Milford, Ohio; notes on interviews in the 1830s with a few Ohio pioneers; a brief journal and notebook (1788) of Israel Ludlow; and an Ohio certificate to practice law (1806) issued to John Armstrong.
