Take it from a native American, you are probably SOL. Not many records were kept on the indians and if you do not have a roll number, then you are going to have a very tough time finding out everything since the indians were basically kept track of by numbers.
Many indians rejected the numbers and they are very difficult to locate. My ancestors did not accept the numbers and the courhouse they were in, in Oklahoma, burned down in the early 1900's and are basically lost forever. So my family has no numbers, not that I or my family wants the shitty free little handouts offered by the govt. for them anyways.
My family has traced its roots back to Martha Washinton's daughter, Patsy Custis, George Washintons step daughter, but nothing past my great-grandmother on my mothers side who was a full blood Cherokee indian.
Good luck on finding anything out, but I wouldn't expect too much.
