Barbara, If you happen to find such information on line, I would love to know where it is at also. As far as I know my GGGGrandfather, William D. Irwin, either was full choctaw or was a white settler who had 2 wifes, 1 white and 1 a choctaw women.. I haven't found any good proof of either but photo's show he is not full white and that he does have indian blood in him.. I know for sure my grandfather was 1/2 white and 1/2 choctaw.. So please.. if any of you know where information like this can be found.. I would also be greatful for the help in finding it.. Jennifer S. Irwin
