Sacheen Littlefeather aka Marie Louise Cruz is indeed Mexican and Danish. I went back seven generations and see no American Indian whatsoever. I'm Latino from Mexico. My DNA shows Indigenous Americas-Mexico and Indigenous Americas-Central. On the map it's southwest USA and Mexico. Littlefeather looks exactly like her two sisters so she didn't have a different father.
