Eddie has kindly provided several records where Goldie's race is recorded. It is very clear that she was not Native American. Sorry.
I have a similar situation with my husband's great-grandmother. They were always told she was half Cherokee. I was skeptical but tried to pursue the possibility with an open mind. Then I saw a photo of her. She was listed in records as white. She didn't look as if she was 50% Native American. So, while there is still the possibility that she had a Native American grandparent or great-grandparent, I am not holding my breath and I am convinced she didn't have a 100% Native American parent.
