According to the Enid Cemetery , Vol I book published by the Garfield County Genealogists, there is a John Hall, died 1915, buried Oct 17, 1915 Section A1 (first addition), plot 17,L7.
I didn't see a George J (only George was George W. born in 1845), or a Jocie (or anything like that).
However, there is a Hall, Keo (STROME) SUDDERTH born Jan 5, 1896, d Dec 18, 1977 with this under "Misc. data" "obit, 2w/John Hall, 1w/W.Suddert" which may mean 2nd wife of John Hall or 2nd marriage to John Hall??? She is buried in Addition 2 (A2) 11,L10
