Sex, Lies & DNA
We all know by now that DNA testing can produce surprises and unearth secrets. Unexpected parent-child relationships may be posted outright by your testing company, but other relationships are harder to identify. What do your matches look like when the secret is further back in your tree? Join us as we explore family mysteries that may be hiding in your matches and discuss ideas for solving them.
