This three-part Imprint series explores a young person’s journey through a tribal foster care system and into a life of advocacy — as well as the challenges a family and the Tulalip Tribes confronted.

Born of History was reported over the past 10 months. It includes a four-day trip in March to the Tulalip reservation, and dozens of in-depth conversations with Andres “Dre” Thornock by phone and videoconference. It also includes a review of thousands of pages of court files and interviews with multiple members of Tulalip Tribes, Thornock’s kin, attorneys, tribal officials, judges, social workers and academics.
