How do I go about finding my biological father after I was adopted? When I was four my mom's current husband adopted me, therefor my name changed to his last name. My birth certificate shows that name. I do not know my real father's name or any other info. I only know my mother's info. Any ideas?

Talk to your mom and tell her it is important for you to have as much information as she knows. Reassure her that you still love her and your stepdad but you need to know.
