How do I go about finding my biological father?

Well first you should ask the person who has raised you if they have any information. If they at least have a name there is your first step. If yoy have a name I would search every website possible. Examples: Myspace, yellowpages, Google. And hopefully you'll get another step closer. Good luck

Get information from whoever raised you. I'm guessing you were raised by a stepfather and biological mother?

Before you can start a search, you will need as much information as possible about the person you are searching for.

Yes, how old are you, where do you live, ( what country) where was the last place the father was known to be, what is his name, what does your mother know,
