There are two Mangum Cemeteries. On is Riverside Cemetary which is just south of Mangum. It is a large cemetary. Most of my relatives are buried at this cemetary. The other cemetary is out near the airport on the north end of town. Not sure of the real name of this one. I will write down your email address and will find some email address for you. I may know someone that can look it up for you.
