I was given up for adoption at birth in Sioux Falls, SD in March 1958. Have since located nateral parents in Cheyenne River Sioux Tribe in 1990. Mother passed away 30 days before I found them , but father still there with two younger brothers, an adopted brother and sister. Stay in touch, but am told that we come from Sitting Bull on my father's side. Would have to come from my Grandfather Henry Red Bear's side. His father is Joseph Red Bear whose parents are listed as father is Red Bear and mother is Appears. Henry's mother is Rose One Bull and her father is Henry Oscar One Bull and mother is listed as Running Bear,Mrs. One Bull. I am interested to learn more about my family on this side as I have been putting it off for quite sometime.
