mother looking for son born 4-6-1966

I am looking for my son, whom I gave up for adoption. He was born at Sioux Valley Hospital in Sioux Falls, SD on April 6, 1966. He was in foster care and then adopted through Lutheran Social Services. Rapid City Regional Lutheran Social Services processed the adoption. I was only 16 at the time of the adoption. On a previous post, the wrong date was listed. I have been praying for him since the day I gave him up. I still have a picture of him taken at about 6 weeks old. I really want to see you at least once, and then you can decide if you want any more contact. I do not want to interfere with your life, but would like you to know I have tried searching for you many times, and would like to tell you face to face why I gave you up. The decision still causes me emotional pain even after all of these years. Love you, Mom
