Who am I? Where do I come from? Why am I the way I am? Mary Beth Sammons follows dozens of individuals as they delve deep into their family mysteries, attempting to discover the truth of their identities, all through the results of a simple DNA test and online ancestry searches. Each journey is dramatically different: some joyously unite with long-lost siblings while others are forced to reckon with a fractured and devastating past. These stories, heart-wrenching and warming, intimate and inspiring, showcase and distill the lessons learned in the search for what makes us who we really are.
