ED , contact the tribal office and get the forms for their role numbers fill them out and send your original birth certificat and your kids originals ( they won't take copies ) to them . They will send them back to you after they make copies , and when they get a chance to look at them and sign the papers you should have their role numbers , my problem is no one kept the role number after 1911 or so and the death certificates are not filled out right , we are in the process of getting them corrected but with you already having yours it should be a breeze for you .
Thanks for the other sights .
