I highly recommend the documentary "3 Identical Strangers" about a set of triplets who were each adopted by three different families without knowing about the other until they reconnected by accident at the age of 20. But it's much deeper than just a story of coincidence and gets into treating people as experiments, a human tragedy and an individual's core right to know their history.

Being an only child I wish this was me.
@PalacinkyPDX What I wish is that I had a sibling one that I found after all these years of being alone. I would even be happy with a sibling that I was at odds with sometimes.
I scheduled this film for my film group, but I was out of town when the group saw it. Everyone said it was excellent. I guess I will need to get it from Netflix.
