I am searching for the parents of my brother in law, who was born about Mar 1947 in Chicago, IL and put up for adoption. His adoptive parents lived on Diversey Ave just before Lawndale, members of St Hycinth Catholic Church.
His adoptive parents have both been dead for many years and they had no other children. At the time of his adoptive mother's death he received his adoption papers which said his natural mother was a Sobieszczyk or married a Sobieszczyk - this is now unclear because the papers were lost in the process of moving. But he was a Sobieszczyk one way or the other and needs help in finding his natural parents.
Any help anyone can give me will be greatly appreciated.
