Hello. I am related to the Gray's in Pontotoc ounty Oklahoma. done a lot of family tree research. That peticular name is NOT familure to me, I take it 1991 is the year he passed away.
IF you have NOT checked this web site it could be very, very helpful. http://www.finagrave.com
2 of my Gray ancestors were murdered in Pontotoc county Oklahoma. One David Thomas Gray ( murdered ) DEC 24 1909 in Allen Oklahoma, also his brother William B Gray, was murdered at Hart Oklahoma, near Ada in 1910. If you don't have any luck with find a grave. you might checK CEMETERY records for Allen cemetery Pontotoc county Oklahoma. My ancestors came from STONE COUNTY ARKANSAS, buried in the Evetts Cemetery. If I find more for you, I will let you know. Peggy
