1992 LICKING CO, OH ATLAS - A COMBINED REPRINT OF 1847 & 1854 WALLMAPS & 1875 ATLASES p111 (the 1875 atlas). Refers to Isaac COOL as "a dashing horseman" who came with a message from the Governor of the State of Ohio to stop the execution (hanging) of Peter DIMOND who was accused of murdering a Mr. MITCHELL in 1825. An S. HAVER had land in either Etna or Fallsbury Tp on p.3 (1847 wallmap) - I'll need a magnifying glass to find him!
The above hanging is also referred to in the 1909 CENTENNIAL HISTORY OF THE CITY OF NEWARK & LICKING CO, OH by E.M.P. Brister v.1 p.384 & Isaac COOL is described as "the jailer".
