Klotter, A New History of Kentucky (University Press of Kentucky, 1997): "The convention ratified the Constitution on June 25, 1788, by a vote of 89-79, with ten of the fourteen Kentucky delegates voting in the negative. Humphrey Marshall, Robert Breckinridge, and Rice Bullock favored acceptance; for some reason, delegate Notley Conn did not vote.)
