Desperate to find family!

I am desperate to find my birth family! Please help. I was born at St. Joseph Hospital on June 23, 1975 and my doctor was Dr. PReston Maclean and my newborn pediatrician was Dr. Ed Hughes. I was 7 pounds and 20 inches. I was born healthy but stayed in the hospital for five days where my birth parents did visit me. My parents lived together. My mother was 20, her name is Jane. She is 5'8, was 115 pounds, dark blond hair, light complexion. She did office work, graduated high school, and was Baptist. She enjoyed knitting, dancing and tennis. Her parents were married and she had three older sisters and an older brother. She is Scottish, Irish and Indian. My father's name is Richard. He was 21, 6'1'', 175 pounds, and enjoyed boating, woodworking and sports. He is English and his father a big man. His grandmother had diabetes. I was adopted through the Good Samaritan agency but stayed at the Cormier FOster Home until I was put with my adopted parents on July 11, 1975. My birth parents went before a judge on July 9, 1975 to surrender their rights. They thought they might marry but I believe they separated. My father Richard tried to find me in 1992 when I was 17. I just found out this info but the contact info he left is no longer current. I really need to find them. I think I have a genetic health condition and I really want to find them. I am their son and love them very much. Benjamin
