If the word "Yellowstone" only conjures up images of the lush landscapes of America's first national park, please forgive us for thinking that you've been living under a rock for the last five years.
That's because "Yellowstone" the television show has become the most-watched scripted series in America since it burst onto screens in 2018.
Cocreated by Taylor Sheridan and John Linson, the Paramount Network series revolves around a ranch in Montana, named after its neighboring landmark.
At its center is John Dutton (Kevin Costner), an aging rancher who spends his life maintaining and protecting his family's land and legacy in the face of myriad threats, and contemplating which of his children will be the right fit to take over his role when he dies.
In recent years, the world of "Yellowstone" has expanded beyond the flagship series. Two prequels, "1883" and "1923," both featured other members of the Dutton clan, revealing more of the Dutton family tree and its ties to the Montana countryside.
Yet there's still one genealogical question that has yet to be answered: Who is the direct ancestor of the modern-day family featured in "Yellowstone?"
The mystery has had fans of the franchise second-guessing themselves ever since "1923" introduced two possible contenders as John Dutton III's grandfather: Jack (Darren Mann) and Spencer (Brandon Sklenar).
Even the stars of the franchise are in the dark about how the two generations of Duttons are related to each other.
"Everyone on the cast is speculating too," Sklenar told Insider earlier this year.
To keep track of the complicated familial connections and the expanding list of new faces, Insider has created a comprehensive guide to the Yellowstone universe's Dutton family.
Warning: Spoilers ahead for "Yellowstone" and spinoffs "1883" and "1923."
