My dad was adopted. He was born March 9, 1949. He was born in Columbus, Ohio His birth mothers name was Dorothy Cantrell. I think she was 21 when she gave birth and it was listed my dad had an older sibling. My dad's birth name was Michael Duane Cantrell. My dad and I have a bone disease and I would love to see if any of his birth family had it. Any help would be greatly appreciated!!!!!
