Kirksey in Chickasha, Grady, OK

I'm looking for cemetery records of D.F. (Doctor Franklin) Kirksey and wife Nora A. (Hornsby) Kirksey who died and were buried in Chickasha, Grady Co, Ok.

They moved from Jonesboro, Craighead Co, Ark, after 1920, to Chickasha.Nora's obit states son, Forest Kirksey, was still a resident of Chickasha at the time (1935).I'm looking for stats on Forest, also.
