If you did not get the enrollment packet for your couple, you may have missed the most information full documents yet to be found! Address: The Oklahoma Historical Society, 2100 North Lincoln Blvd., Oklahoma City, Oklahoma 73105-4997 I have a family who were in the same area. The husband was not Indian, the wife was one-half Chickasaw and was Eula Eunice JAMES, daughter of Simon JAMES and Virginia "Jennie" Caledonia BYRD. I got a packet for the husband, William Pouncy JEMISON which showed there original marriage in Texas before they went to Indian Territory. At that time 1891, intermarried non-Indians were accepted as intermarried members. Later on, only those married by TRIBAL LAW would be acceptable and it was retroactive to day one. Many couples remarried by TRIBAL LAW and all that information is shown in the ENROLLMENT PACKET. Write to the OK Historical Society and check on the current fees. IF you live in Oklahoma, there is no fee. Out of state pays $20.00 research fee (the last I heard) plus nominal charges for copies and postage. You will not believe the wealth of knowledge to be had in these records. Of course, as in all things, some have more information than others, but all should tell you the names of the parents of the one who is the subject of the record and whether they were of Indian blood or non citizen, whethere they were living or dead and if they were on any of the rolls, the name of the Tribe. Good Luck in your seardh!! I was well please with every packet I got from the Society. Billie
