My mother always said that her grandmother was half Cherokee. However, her father grew up in Comanche territory. That would make me 1/16 "Indian."
I had my DNA tested at Ancestry.com. It didn't show any native American ancestry... but it does show Indian ancestry--from India.
Those DNA tests for people and pets are crap. We got a new puppy about 18 months ago. Since we knew the dog was of mixed heritage, my wife purchased a DNA test for the puppy, young dog actually.
If I could post a picture you would see a 28lb, long-legged black and brown mini-Doberman.
The DNA people said I had a Chihuahua - Akita blend. Like I said ... pure crap.
