I was apdopted in 1967 at birth closed adpotion. I''m 45 and want to find my birth parents. What do I do

Best place to start is to get as much information as possible from your adoptive parents and register on reunion websites.

First why do you want to find them ?

After this what has your adoptive parents told you, often they know more than they tell, and would have gotten copies of the court doctuments, they would have know he attorney used,

Also normally the "new" birth certificate still shows the city and hospital that you were born at, so if they were still posting births in the news papers, you can do searches of news papers to try and find some info

You post your info to the dozens of reunion sites
