The town, you mention, is probably Cooperton, Kiowa, OK. I have Cemetery listings, for Kiowa County, except for four Cemeteries.
I could not find your McGee, but did find a couple that may help.
These are in the Roosevelt Cemetery-Roosevelt, Kiowa, OK
McGee, Fred 12-18-1915 to 7-21-1994 Pvt. U. S. Army WW 11 McGee, James, 1914 to 1985
The four Cemeteries, I do not have listing for are. Lonewolf--in Lonewolf, Kiowa, OK Hobart Rose Cemetery-Hobart, OK over 14, 000 burials a possibility. Need to check with the Town of Hobart, to see if he is listed. Mountain Park Cemetery-Mountain Park, Kiowa, OK Mountain View Cemetery-Mountain View, Kiowa, OK
