Not knowing a parent

I just wrote a blog in the form of a letter to the father I never met.
Has anyone else never met their father or mother or both? It's a pretty
intense thing to go through. I'd be very interested in hearing others
experiences and how they have reacted to it and let it effect them in
life.
