I just found something refering to a Cooley cemetery in Mercer Co., Ky.  The person listed here is a brother to Margaret Kirkland that married Randolph White.  They were neighbors of John Cooley, Sr.  You may remember that four of Margaret Kirkland White's children married John Cooley, Sr. descendants.  If this Cemetery still exists, might find the date for the death of John Cooley?  Wife???
