I used one a few years back to find a Witness to a Will. It cost €500.00 to find the person but for the Executor of the Will it was well worth it. It did feel very duck and cover, as I had to meet the invesitagor in a car in a park. But he was very nice and did an excellent job and found the person in less that 4 days.
thanks pinkybear but other routes exhausted due to stonewalling by a certain organisation who has all the info and won't share.some info already to hand but limited to a name and dates
I have come accross that before in a place I worked, I was appauled and really saddned particularly as I had given up a child for adoption and always live in hope that he will easily find me
