My roots go back mainly to NC then TX then Chickasaw Nation, to OK territory and OK state. I did a novel based on my grandfather's life called Austin's Legacy --very limited distribution --just my kids, my two living uncles, my two living brothers and to the widows of my other two brothers. It begins in NC when Austin was 6, for I wanted to show him with his Mother, Mary Anne Julian Coffey who died when he was 7. I have a firm conviction that his mama shaped his personality because of the way he treated me and my Mother, his daughter-in-law. It was a neat trip back in time. I am a retired academic librarian and my one younger brother who is a principal of a public school in OK and still owns the old home place now that our Daddy is gone, pronounced Austin's Legacy EXCELLENT. Even my most critical uncle found no real flaws in it and both uncles contributed a great deal to the writing of the manuscript. OKC and Muskogee would be good places to research. There is a set of microfilm or maybe it is microfiche called either Pioneer and Indian Papers or Indian and Pioneer Papers which could give you good sources. Many western history libraries probably owns this source, the product of interview done during the depression of all the older citizens red and white they could locate and get to talk. Kiowa, Comanche, Caddo, Cheyenne, Arapahoe and Apache might be sources also. I think there are 67 "tribes" represented in OK, not just the 5 civilized tribes--Muskogee, the capital of the Creeks also set up a big library on the 5 tribes and Arkansas was the territory hub which ran much of the federally involved activities before OK became a state, but I'd start with OKC and the Oklahoma Historical Society Library as the best home base to begin. I just mention my grandfather, for his line goes back to the Bullocks of Bermuda and he had connections with Indian Territory and yet was not Indian. I studied to be a teacher as in OK, but it was not until I discovered my grandfather's connection to the Chickasaws, that I explored any of this white day laborers and tenant farmers to replace the slaves the Indians had owned before the Civil War. Oh, how much we do not know!---------Hope this helps a little bit any way!---Charlene
