So I might have Native American in me??

So this Thanksgiving I was at my grandma's house in Marshall, Texas and while at the table with my cousins, aunt and grandma and we were talking about something and it lead to us talking about our family and apparently my great great great great great great grandma was full blooded Native American. Sooo I guess that means that I have some in me?? If so that's whats up. My cousin started to work on a family tree so I might find out more later. I think the Native Americans my family came from is from Oklahoma. I wonder if I have enough Native American in me to get some money for school?? If so that would be ballin.
