Thanks to 23andme you can prove your ancestry. Has granny ever proved her ancestry? So maybe you are different then her?
I am different than Warren! I would never have been able to sit through an interview without bursting out laughing if I had ever claimed this. (She, on the other hand, became a tenured professor at Harvard.) I look much more like George Custer than Sitting Bull.
I think Warren claimed that her "high cheekbones" proved her Native American ancestry. No need for any of that silly DNA stuff.
My daughter has been asking me what I'd like for Father's Day, and the thought did cross my mind to ask for some "Native American Pride" attire, like a cap or a T-shirt. All in good fun.
Unfortunately, I think she'd disown me.
