Everyone’s journey will be quite different, I knew at an early age I was adopted and knew the names of my birth parents, in those days it was unusual for the father to be on the birth certificate of people that were unmarried.
It was not until Facebook and more recently DNA advances that certainty was confirmed for my circumstances. I had a gut feeling not to contact my birth mother when she was alive, and was proved right not to do so.
I do have a very positive relationship with two half sisters who I contacted after her death.
I’ve never been able to trace my birth father for certain.
There is a lot of research that can be done these days that was very difficult in the past.
Good luck in what you decide to do.
