I need help; I know I am of Sioux Indian descent, but I do not know through what tribe, or person for that matter. I asked my grandmother about this, and all I could discover was that the blood comes from my great-grandmother's side. However, I have no idea how to contact her, and I believe her and my grandmother (mother and daughter, respectively) are not on speaking terms (I have a dysfunctional family). I believe my great-grandmother's married name is Boehme. If anyone has any information, or any ideas on how I might find out more, please let me know. Thanks.
