I was 32 years old by this time and had been seperated from my natural parents for 30 years. My natural father is possibly still alive, but hard to find as he was or still is a drifter. Look perhaps at relationship with my adoptee mother and father and the ramifications if I had remained with my biological family.
Paper is designed to help others understand who they are no matter what the family background.
Will try to include some case studies. I feel that a non biological parent can love a child just as much as a biological parent can. I see where you get the missing link from. Good luck on your paper. He left my grandmother when she became pregnant and then my grandmother married my grandpa.
