These posts about Central Oklahoma State Hospital-Cleveland Co. are very interesting.My great grandfather was at Central Ok. State Hospital from 1944 through 1951.My husband's father and mother also worked there in those early years as attendants, while getting their degree at the University of Ok.
I was able to get my great grandfather' records from the Ok. Dept of mental Health and Subtance Abuse Services. I also wrote to Griffin Memorial Hospital, P.O. Box 151, Norman, OK. for records. They sent me his death cert, medical reports and cause for admission.He was later transferred to the Lexington OK. annex for the state hospital, where he died.
I will ask my husband about a cemetery on the grounds and other relevant info you might be interested in.
