Son of adopted boy born in Charelston S.C. March 5th, 1957 searches for his birthmom

Hello eveyone. My name is Shane Barber, and i am looking for a family member lost by adoption. I relize i'm not like most people looking for their parents, because i'm looking for my grandparents. You see, my father was born in Charelston in 1957 and was adopted when he was still an infant. He was raised and had a good life, and just recently his adopted mother died. Now, i think it's time we find his real parents. I loved my grandma dearly, but ever since I found out he was adopted, I've felt like a part of me was missing, and I want it filled. Even though he won't admit it, i know my daddy wants to find his parents, i think he's just afraid of being hurt, and i must say so am I, but not enough to give up on my dreams of reuniting my family. So grandma, if your out there, I love you, and I want to meet you, so please respond. Heres some info about my father to help idetify him to my real grandmother. Birth city- Charelston S.C. Birth date- March 5th, 1957 Birth name- Baby Douglas Also, heres some info on my grandma She was still in High School when my father was born and it was said by the hospital nurses that she had the fairest skin they had ever seen. And my grandfather He was a textile worker in his forty's. Again, i really want to meet my real grandmother so if your out there, please respond, I love you. Shane Barber
