Mary, Sometimes you can find early obits.In Oklahoma City there is a Historical Society Library in the Historical building that is close to the Capital Building.There is also a Newpaper Division that has most newspapers on microgilm.You might also check the Libraries in the area where a person died they sometimes have local papers on microfilm.
In the Pushmataha Cemetery book I found lots of Smiths.I did not find Kansa Elizabeth Rains SCOTT.If she had TB she may have been in a special treatment place for TB.They use to send people with TB to Sanatariums for TB.She may have been burried close to that place.
I found the following SCOTTS in Cemetery book. William Cury SCOTT 25 Feb. 1891 - 6 April 1944 Addie Louise 1931-1967 Lurtis W. (Lart) 31 Mar. 1917-9 Oct. 1970 C.C. SCOTT 8 Feb. 1897-13 Sep. 1920 he is in Antlers Cemetery. Rosa Bell Scott 1905-1941
There is a supplament to the cemetery book that I have by Kay Brown Black.It is available at the Antlers museum.It has some people in it that were not in the cemetery book.I believe she had taken them from newpapers etc.I think it is available for purchase.
