Veronica (Mary) Eleanor (Lou) Thompson (Hutchens) (Watkins) - My Cherokee Great Grandmother

I've been told by my biological Grandmother Gladys Orr (Gladys Lawson) that my Great Grandmother was full blooded Cherokee. She goes by the name Dasie or Daisy. Gladys is now deceased. My Biological mother Namomi Faye Hutchens (birth name Watkins) whom is alive chooses not to relinquish who my biological father is or any relative information on her father's side. FYI.........I was put up for adoption at birth in a third world country.
Thank you for your interest.
