Stevie's Heratige?

[Meowi]

Ok, I've been really interested in finding about Stevie's ethnic background. I have known for a while that she has German roots, but I did not know this:

At the very end of the show, she said "One more bit of trivia... Like, half my family is from Colorado, and my great-great-grandmother crossed the desert leading into Colorado to come here... and she was the only survivor of a huge Indian massacre! So now you know that."

This was written into a review for a Show she did for the Enchanted Tour.
So what do you think, do you think she has Native roots?

If you have any info, please add
