Ancestry/Genealogy

Something similar happend to me a few years ago. I received a message through 23andMe from a 2nd or 3rd cousin who had been adopted at birth. She knew who her birth parents were and had been in contact with both of them for about 10 years.

She also was in contact with her maternal grandparents, but her birth father claimed he did not know where his parents were (which turned out to be a lie).

Her paternal grandfather is my father's first cousin, and he was alive and well, living in the same place for the last 30 years.

My mother happened to have saved a bunch of correspondence with the adopted woman's paternal grandfather, so I contacted him by mail. He called me one night and told me a very sad story:

The paternal grandfather and his then wife wanted to adopt the baby girl at birth, but the maternal grandparents wouldn't allow it. She was put up for adoption through an agency. The paternal grandfather had been looking for his granddaughter for her entire life. He cried when he and I talked on the phone. I gave him his granddaughter's phone number and they have visited and stayed in touch ever since.

I was also able to help her find her paternal grandmother, though the grandmother was mentally ill by then and they don't have much of a relationship. But at least she found all of her grandparents.
