Good luck with this, it must be hard knowing you have family out there but not knowing where.Just wondering if anyone has been through this process before and how you went about it. I am literally at day 1 of the process and the amount of information on the web is staggering and I am not sure where to start.
Have you tried the Library for information on Census etc.we have the birth details so that is not a problem. Intermediaries are looking in some cases for £2500 to do the search.
but we literally just have the birth details
We know they were possibly in Newcastle but that was 50 years ago.If you know some details - names and ages - you might try local facebook groups? or do you not know anything about the area etc?
if you try some of the bigger local groups that have tens of thousands of people in, and post their names and how old they would be, along with why you are looking for them etc people often share the life out of it. its worth a shot vs £2.5kWe know they were possibly in Newcastle but that was 50 years ago.
