Since my post yesterday, I had the occasion to visit the library and check cemetery records.While I was able to find a few more "FORD" surnames, I failed to find your Hugh.From past experience, I have seen that a significant number of people that died prior to about 1922 did not have grave stones.Whether by attitude of the times, economy, or maybe just non-availability.I have found walking many a cemetery that there is evidence of what appears to have been a wooden marker, long since lost through the years.Possibly, that is the case here.
I found the following additional FORD burials -
Henry Ford (no dates shown) in the Pollar Cemetery (that is near the Old Frisco area, but slightly west of same.
John Henry Ford 15 Nov 1936~1 Jun 1969 in the Mt Zion Cemetery (which about 14 miles or so west of Idabel)
Julia McGaha Ford 1891~1934 is in the Old Masonic Hall Cemetery in the no longer existant community of Ultima Thule (on the State line with Arkansas, east of modern day Eageltown)
I also found that Hugh's father John A. Ford is indeed buried next to his wife in Bokhoma Cemtery, with the following dates reflected 29 Feb 1844~2 Oct 1928.Buried next to C.W. Ford, as I previously mentioned.
John had a rather nice write up in a local paper of that era, which reads as follows (McCurtain County Gazette, Saturday, 6 Oct 1928):
"JOHN A. FORD, A PIONEER OF McCURTAIN COUNTY, DIED LAST TUESDAY IN HAWORTH"
"John A. Ford of Haworth, an ex-Union soldier, was born at Columbia, Tennessee Feb 29, 1844.He received limited education during his early life in the schools of his native state.Mr Ford professed religion more than 61 years ago and has lived an upright life.
Mr Ford believed in the future of McCurtain County.He believed that within the coming of the next quarter century that it will still make the same rapid progress in the ways of improving that it has in the last quarter century and be a better place for man to live in.He has, unhestitatingly, stood for law and order and the suppresion of crime in his entire sojourn among us.Mr Ford was an ardent believer in education and the Christian religion.
Mr Ford died at his home in Haworth Tuesday at the age of 84 years.
Funeral services were conducted by Rev. Appleberry, at the Methodist Church at Haworth, at 1 o'clock Wednesday and internment was had in the Bokhoma Cemetery."
That is about all I can offer in your quest, but hopefully I was able to fill some gaps for you.
