Hi Quaker22
Welcome to Rootschat
Lots of questions asked and lots of possible answers.
Firstly, have you checked the 1939 register on FindMyPast with a first name and date of birth?
We can't do look-ups for you but you can do a free search here
http://www.findmypast.co.uk/1939registerThe inference here is that he will now be deceased because there shouldn't be anyone listed who was born less than 100 years ago, names with a 1916 date have been released.
If he has died, than there may be some names there worth following through.
Have you found your father in the 1939 register?
The General Register Office (GRO) adoption index is not avalable online but at all of the 7 GRO host sites. However this index only records the names after adoption and has no obvious link to the GRO birth index. If you dod not know the name after adoption, then this route won't be of any help. I do visit the GRO hosts sites in London and can check for you if there are some names that might be potentials for example where you have a 'child' on the 1939 register but there is no obvious entry in the GRO birth index.
You mention that you have a birth certificate. If this has been purchased more recently than the birth, then it should be annotated on the right hand side to show there was an adoption. If you do not have the irth cert, then applying to the GRO for a copy n his birth name should clear up once and for all whether he was legally adopted after 1927.
It was not unknown for married parent with legitimate children to give them up for adoption, they might have been struggling with poverty or illness or not coping. Today Social Services would step in to help, not always an option historically.
There are some other questions that shouldn't be asked on an open forum but you need a higher post count to send an receive personal messages. If you can increase your post count I might be able to help off-forum.
