Dr. J. C. Gray practiced in Mt. Vernon during the Thirties, Mrs. Johnson mentions him in her history as having treated one of her children who died. I also find an account of Dr. Gray being called to Marion to treat Rev. Ingersoll, the father of Bob Ingersoll, in his last illness.

Among the other early phycicians in Jefferson County there were Dr. William H. Short, Dr. Grethem and Dr. Thomas Johnson, but as they left but few foot-prints on the sands of time, I am unable to give any detailed history of their activities.
