I want you to finish this thread! I can't believe they have not made a reality tv show about adoptees. i find this a lot more riveting than anything else.
I am doing both ancestry and familytreedna. I had not heard about the 23andme until I read this thread. The hardest part is trying to get information from other people who might not want to share the details. Ancestry is hard because all the living people are shown as private in the tree unless they will share it with the settings changed. I am much older so I figure that maybe finding another family member at this point in time might not be as awkward as it could be for some. I would like to find either mother's or father's birth line. I wish you success.
Sadly, I had one person tell me they didn't use their parents real names on ancestry or even the right sex. That is very unfortunate and could cause some real problems in the family tree.
