I have added answers in between the questions Can anyone recommend the best people/ methods to research this further? I have written to a few adoption agencies in Wales but have not received any replies yet. Try the Salvation Army. They can find people and will but it will depend on what the person you are looking for wants as to whether they connect you. Were adoptions private in Wales in 1966-1967 All adoptions after 1927 had to be legalised and registered. This wouldn't stop someone giving their child to a relative to bring up, we only have to look at the number of people who discover that their oldest sister is actually their mother. If you can find the birth certificate of the person then it will say on it if the person was adopted officially or not. Ann Macey In Sunny Newport, Gwent, Wales
