I have finally gotten a death certificate for Mary.I found out that she died in Texas but was buried in Oklahoma so I got a death cert from Texas and my ggrandfather I sent for a death cert in the county (Tillman county) and they said that they looked but that they needed a more specific date. I have heard that it is hard to death certs out of oklahoma and this would have been a death cert in 1911. So I am wondering if my ggrandfather died in Texas also. I am sending for a death cert there just in case.They were both buried in Davidson Oklahoma in the cemetary.Their is no headstone though.I talked to the people who take care of that cemetary and she said that their are many graves without names.I have also looked for a obit in the Frederick libary (biggiest town near there)and they did not find an obit from the paper. Someone suggested that I try to get probate records from the county clerk.So I am also going to try that avenue. Thanks for your help!
