I am looking for any family of my grandmother: Alice Ruth Ann Schrieve.Her parents are John and Alicia Schrieve. She is half Sioux Indian and believed to be a grand daughter of Sitting Bull. She has an older brother named John Schrieve. I am finding out Sitting Bull had at least 9 wives. My grandmother was orphaned at 5 years old in Pierre, South Dakota and lived on the reservation, which was probably the Standing Rock Reseveration. I would really like to know how her parents died. She was taken into the Tate family at 5 years old to do laundry. She later married Warren Hedges Smith.
