Here's how you can tell she's BS - she doesn't identify her tribe. People who have sufficient Native America heritage to identify with a particular tribe don't run around saying they are Native American - they're whatever their tribe is. My dad is registered with the Florida Seminoles, and he refers to himself as a Seminole, because that's what he is. No legit person with tribal recognition refers to themselves as she does - you use your tribal affiliation. The fact that she cannot state a tribal affiliation should tell you all you need to know.
