search for brother born 1965

indigo I am looking for my sibling whom was born in 1965. The state of birth was South Dakota. The Adoption agency that dealed with the Adoption was Luthern Social Services. I have located B-mother,and oldest brother who was born in 1961. He was born in Iowa, through Luthern Social Services. I was born in North Dakota. Adopted through Luthern Social Services. We had some research done and a possible name that came up was Brian Shoemaker. For youngest sibling. If anyone has any info myself and oldest brother would really like to talk with him. There is medical info also that should be related down. Thank you, Lisa
