The cast of the Yellowstone spinoff prequel 1923 has revealed Jack Dutton, a member of the third generation of the Dutton family, completing Yellowstone's seven generations. The 1923 cast will show viewers how the Dutton family established the largest cattle ranch in the country in arguably the worst decade in Montana's history.

The arrival of Jack Dutton could also mean the end of the Yellowstone Dutton Ranch, as it has been implied throughout several episodes that the Duttons will lose their land after owning it for seven consecutive generations. The 1923 cast also helps paint a more complete picture of the Dutton family's final fate, such as the possibility that Kayce's visions in the Yellowstone ending were hinting at the end of the ranch.
