In Search Of Birth Family

I am in search of my birth family. I dont have much ino but this is what i got. My papers are from North Carolina Department Of Health & Human Services. I was born on July 20,1953. The couple that adopted ne where named Edna Chapman and Clyde Smith of Dallas, Nc.If info is correct. My birth mother was 20 at the time of my birth so i figure she was born in 1933 and would now be 70 yrs. old now. My birth father was 27 at time of my birth which puts him being born in 1926. The info on papers of my mother are.. 20 yrs old 5'4 115 lbs Caucasian female with blue eyes,brown hair. She liked to crochet, and do embroidery and sew. The last grade she completed was 9th. Her favorite subjects were History and Spelling. Talents were playing piano and draws. Her religious preferance was Baptist. Her occupation was Spead Maker,Housekeeper. There was also a daughter born in 1950. Her reasons for adoption was, Planning to marry someone else who is unaware of the pregnancy & adoption. The relationship of mother and father of the child was, Hoped to marry him but he wouldnt accept her daughter. There was 2 grandparents that died in their 80's and 90's due to stroke. And the biological grandfather had low blood pressure. I was a single birth child and carried 41 weeks. It does say that mothers RH factor was positive. As for the info on the papers on father, He was 27 brown(dark) hair blue eyes, He was 6' 162 lbs.his complexion was medium. He liked Baseball. special talents were playing guitar and singing. His occupation was Textiles,timber. He was divorced and was not involved with birth mother during pregnancy. Birth parents were Dating so it says in his profile of these papers iI have. Birth mother thinks birth father was a only child and knew nothing about his father so the papers say. This is everything that I have. I have done the math and the sister of mine should have been done with school in 1967. I was raised by couple with the last name of Smith. Mr and Mrs Clyde Smith. There is one living family memeber left who refuses to tell me anything about what happened or anything back then Says she sword she would take this secret to her grave has she promised. My sister would or should be around 53 now and my birth mother to be 70 and my birth father should be around 77 now. I grew up in the Dallas Nc area all my life. My adopted mother and father have past away and i never got any info from them cause i didnt want to hurt them.
