I am looking for my great grandfather, John Flynn. I have been told that he was born in Illinois in 1869. I know that he married my ggrandmother in Krebs, I.T. on June 10, 1898 and died in 1909 around Coalgate, Okla. I'm not sure where to go next. I do know that he worked in the Coal mines and as a farm laborour. Would I need to go to the Oklahoma Historical Society and try to locate him in the 1870 Illinois census? If so, how would I go about that since I do not know his parents or what part of Illinois he may have been born in. Any suggestions would be greatly appreciated. Thanks, Sheryl
