How can I find my real dad I've been trying to find him for years

I need help

When was the last time your mom saw him, where was he seen last?
What is his name, about how old is he

Do you have any information about him? (The more you have, the better it will be.)

You will need his full name, maybe his mother's maiden name, his SSN, his birthdate.

Are there any relatives or friends of his that you are in contact with? What about your mother's knowledge of him? How long has it been since he was in your life?
