Hi Alan
As a new member here you may not have discovered the amount of posts here where people ask for help looking for birth relatives.
It looks as if you have received information that has been helpful for you.
I would however urge caution if the lady you seek is still alive and you want to make contact with her or her family.
At the time of your adoption, the subject was hugely sensitive as to the reason for your adoption and for the family adopting you.
You will also find topics here where people tried to make contact but they were rebuffed.
I suggest that you take some time to think about your action plan.
If you haven't done so, get a copy of your adoption file from the GRO, but you might have this and think about using an intermediary service to make an approach on your behalf.

Good luck.
