Vicki, You can write to Joan Cargill at Route 1, Box 380, Cushing, Oklahoma 74023. She has a map of the cemetery with the names of who bought the plots on it. So, even if your relatives don't have tombstones, she will know who purchased the plot perhaps and when they were buried. I don't know exactly how much information she has. I am sorry but I do not have her phone number. She responds pretty quickly to the written requests though. Hope this helps. Edie Brand Katy, TX
