It is a stereotype that Indian people get things for free. And this is part of what feeds those who wish to find a "Indian" hidden in the family tree.
My dad was a full blood Shawnee, his name was Lemuel Charley Squirrel, my mother was Chippewa, I was raised as Shawnee.
I pay taxes. I have to pay for medical insurance. I had to pay for my education and my son is currently in debt for his college loans. I am paying for my house. I also pay property taxes on my house. My tribe does not have a casino. I do not get a government check every month. Oh the list goes on and on...
What does being Indian get me? I am a part of my culture, a part of my people, I was raised in Indian ways, I know my language, and ceremonies.
Being Indian is not about finding a ancestor, it is about being raised within our ways, being a part of our ancestors.
Thank you for taking the high road and wanting to have documentation... but let your family know, having a Indian in the family tree does not mean you suddenly get benefits.
