My son was given up in 1979, I would like to find him but donnt know how

You post the data on as many of the 100's of adoption connection sites as you can.

You write a letter to be put in the file with his birth certificate if he goes looking ( allowed some places)

You contact the agency that did the adoption for any info

Was your adoption open or closed? Would he have your name? If you think he has access to your name, join Facebook or myspace... because he might be looking for you on there. You can also join the sites like the person listed above. Do you know anything about him? Maybe you can go on Facebook and look for him.

Did you read the sticky at the top of the adoption boards before posting?
