Dear mary: i live in bethany oklahoma and my ggreat grandfathjer is also buied in oaklawn cemetary, when i was looking for him i did not have any information on where he was interned, so i just began calling all the county offices, i called the sulphur conty office and thet told me exactley where he was burried and other inportant information, even what he was burried in and how much it cost, he died in 1927, not sure what year your kin died but im betting he is listed in the register office. i plan on a trip there soon (my niece had a baby 2weeks ago and she lives there) if you find out if he is there i will take a picture for you on my digital camera and send to you, or take some hard copys for you also, no problem i love to help break down theat invisable brick wall of our late great ones. let me know ok. sincerly katt baker
