My dad was adopted at birth in the 30s. He has now past away. How can I find out who his birth parents were?

Private adoption? Closed or open? What year?

Do you have any info on his birth parents?

There are various adoption sites where you can post all the info you have and hope that someone recognizes it.

Obviously with identifying info the road is easier.

He was born 13th december1933 I think in nottingham uk well that's where he was raised that's all I know

I can't help in the UK. Sorry -

I'd try the various online adoption sites.
