The Washington Post has published an interesting article by Tara Bahrampour about adoptees using DNA to find their birth relatives, sometimes even their birth parents. The article states:
Most people who register with DNA databases are looking for information about their ethnic origins or exploring distant branches of the family tree. But the rapidly expanding databases have also had an unintended consequence: They are helping people find biological parents whose identities had long been mysteries.
The implications are wide-reaching. For adoptees, birthparents, children of single mothers with unknown fathers, and fathers unaware that they had a child, the answers to lifelong questions or the revelations of closely guarded secrets may now pop up in inboxes without warning. The technology can raise privacy concerns and lead to emotional complications.
Some adoptees have found biological relatives when they didn’t set out to.
