Looking for birthparents. I was born in Dunoon, Scotland.

No.... I cannot locate them.... I have paperwork on them all ... that lead up to the early 1970's. I found a death certificate for the oldest bio-brother, he passed away a few years ago... plus my Bio-Sister got married in 1986... but that is all the info I can find. I think I may just have to fly back to Scotland and find the correct government beurocrat and look him in the eye and ask him for assistance....
