Are you sure he was born in Bokchito and didn't just live there?How sure are you of his exact date of birth?What was your grandmother's name?
The 1930 census for Bokchito, Bryan Co, OK has this couple: HUNTER, William O. age 43, b. TX, father b. MO, mother b. MS wife May age 29, b. TX, father b. AL, mother b. TX
There's a WWII draft card for William Oliver HUNTER b. 14-May-1885 in Hood Co, TX, registering in Blue, Bryan Co, OK.Employer was Frisco Railroad.Person listed who would always know his address was Frances Marie HUNTER.
The 1900 census for Sterrett Town, Choctaw Nation, Indian Territory has this family that's a possible match: HUNTER, Charles b. Aug 1852 in MO, married 19 yrs, both parents b. MO wife Susan b. Nov 1853 in MS, 10 children born, 10 living, both parents b. MS son Chas F. b. Dec 1881 in TX dau Mary L. b. Nov 1884 in TX dau Cora L. b. Aug 1887 in TX son Wm. Oliver b. May 1886 in TX dau Minnie b. Apr 1889 in TX son Jeff T. b. Aug 1890 in TX son Geo. C. b. Mar 1892 in TX son Joe M. b. Apr 1894 in TX son Ja--- C. b. Mar 1896 in TX
In 1900 in the same location, father Charles is listed as James C.children Charles, Cora, George, Joe and Clifford (possibly the Ja.C. listed above) are still at home.Widowed daughter Mary GIST and granddaughter Pearl GIST, age 5, are also living with them.
There's a marriage record for a J.C. HUNTER to Susan AWALT on 3-Mar-1881 in Navarro, TX.This date fits with what they said in the 1900 census.
I can't find William in 1910.The only other possible match I can find is 1920.There's a William E. HUNTER, age 34, widower, born TX, father b. MO, mother b. MS, living in the household of Claud BRACKETT and family in Bryan Co, OK.Everything fits to be the same William except the middle initial.I am only able to see a transcribed copy of the census, not an actual image.It's possible it's a transcription error.
