But why did she claim it at all? Even if her family's story was correct, having one Native American ancestor at some point ages ago, does not make you simply 'Native American', does it?
I get that she believed that she was small fractional Native American if that's what she was told (and she thought a couple of percentage points on the test proved her right, so she already knew it was very small.) But she didn't claim to be small fractional Native American. She claimed to be simply 'Native American, period'. I can't see why she'd do that?
