my husband was born on 12/5/74 and was not adopted until late 77/early 78. He was born in Muncy Creek, PA as Jonathan Chrys Heenan. His name now is Jonathan R. Mickson. His adoption was through the Childrens' Aid Society of PA, and through his aparent's lawyers. He knows he has at least one sibling, age unknown. Parents' names are unknown, hospital unknown...
