These three films offer powerful testimony to how uncovering the detailed history of one’s family of origin can open a path towards healing from transgenerational trauma. By bringing buried histories and inherited wounds to light, the filmmakers begin to understand what had previously seemed inexplicable: the recurrence of harmful patterns of behaviour in “Something Familiar”; addiction in “If Pigeons Turned to Gold”; and the origins of persistent interpersonal difficulties—and possible ways out of them—in “Last Letters from My Grandma.”
