Yellowstone, a series obsessed with legacy, explores the Dutton family's century-spanning epic as they care for their Montana ranch and intergenerational trauma. Prequel spin-offs 1883 and 1923 delve into the upper tiers of the family tree, chronicling key Duttons such as Tim McGraw and Faith Hill in 1883, and Harrison Ford and Helen Mirren in 1923. The latter faces the challenges brought by the 20th century, including disease, drought, the Great Depression, post-war fallout, and violence that has always haunted the family. Despite the lack of an official family tree, the shows reveal possible knots of the Dutton lineage. Spoiler alert for Yellowstone fans who have not watched the spin-offs.
