How can I get more information about my birth parents?

Ask your adoptive parents.

We need more information about what you HAVE done in order to help you.

Hi, my adopted parents have passed away. I don't know where to start looking for information. I also would like to know their medical history for myself. Where do you think I should start.

How long ago was your adoption?

Generally, I tell people to start with their adoptive parents to get information on the adoption agency used, so that you can start there.

I'm assuming that your adoption was pre-1990, and is completely closed.

However--unless you have a legitimate medical NEED to know, unless your birthparents are ALSO searching for you, you are probably not going to be able to get much, if any, information.
