Male born June 23, 1975 Caldwell County North Carolina

My name is Stephen Gonzales. I was born on June 23, 1975 in Caldwell County North Carolina. To my knowledge my birth mothers last name at the time was Martin and she had other children. I was adopted at birth and brought to Yuma, AZ. As far as I know my adopted mother & birth mother's sister were friends in high school. Any assistance would be great.
