Hi,
I was wondering if I could get some advice on finding out who my biological grandparents are. ........ ......... I wrote to the place where he was put up for adoption and they said they couldn't help as his biological mother may still be alive.
Did they mention anything about your Dad's biological father? Or are you saying that you were informed that no information was recorded about your Dad's biological father?
Is it possible that your Dad may have sought to find information out himself, or at least registered for contact if his biological parents were to seek to make contact?
If his birth mum was not married when your Dad was born, it is quite likely that the options available for her to raise her baby were very limited, or perhaps non existent.
Have you sought advice from your grandparents (the people who adopted your Dad).
There are likely to be professional organisations that can help, rather than you tackle the search yourself.
Cheers, JM
