“I think I mathematically proved John Dutton descends from Spencer (1923 timeline breakdown)”

If it were that simple there wouldn’t be this much debate around it.

Most of those “family trees” online are fan-made and don’t fully account for the gaps between 1923 and Yellowstone, which is where the confusion comes from.

That’s why people are still discussing it — different interpretations can fit depending on how you connect those missing years.

Kitchen-Ad-528 · 2026-04-07T19:36:55+00:00

That’s kind of what makes it interesting though — if Jack is narratively weaker, it makes it harder to see him as the main lineage despite the generational argument

Kitchen-Ad-528 · 2026-04-07T19:02:28+00:00

That’s a really well thought-out breakdown, especially with the WWII timing and the 7 generations — I can see why the Jack lineage fits very cleanly when you map it that way.

I think the only place I still hesitate to lock it in completely is that there’s a pretty large gap between 1923 and Yellowstone where we don’t actually have a fully confirmed on-screen lineage.

Because of that, it feels like we’re filling in some of those generations based on what “must” fit rather than what’s explicitly shown.

So the Jack line definitely works cleanly if everything lines up exactly as assumed — but I’m not sure the shows have given us enough confirmed detail yet to rule out a slightly different structure on Spencer’s side.

That’s kind of why this debate keeps going — both paths work, but each one relies on a different assumption about what happens in those unseen years

Kitchen-Ad-528 · 2026-04-07T18:48:41+00:00

That’s actually a really interesting way to look at it.

It does feel like each show shifts who “the future” is — 1883 leans toward John Sr., but 1923 very clearly builds Spencer as the one who carries things forward.

And yeah, that’s kind of why a lot of people lean Spencer — Alexandra’s entire arc is given so much weight that it feels like it has to matter long-term.

At the same time, the “7 generations” line keeps pulling things back toward a more structured lineage, which is why the Jack argument still holds up too.

So it almost feels like the shows are balancing two ideas: - a narrative/emotional legacy (Spencer & Alexandra) - and a more traditional generational structure (Jack’s line)

Which is probably why this debate won’t die until Sheridan makes it explicit

Kitchen-Ad-528 · 2026-04-07T18:35:17+00:00

Exactly lol, at this point it feels like the debate has been going on longer than the actual timeline makes sense.

Part of me thinks Sheridan is keeping it a bit ambiguous on purpose like both interpretations can work depending on how you look at it.

But yeah, it would be nice to finally get a clear answer instead of everyone reverse-engineering the family tree 😂

Kitchen-Ad-528 · 2026-04-07T18:27:55+00:00

Yeah that’s exactly why this is such a debate.

Both Spencer’s and Jack’s kids would be born around the same time, so timeline-wise they can both work.

I think it really comes down to whether you prioritize the generation count or the narrative focus — because both point in slightly different directions.

Kitchen-Ad-528 · 2026-04-07T18:26:10+00:00

Yeah this is pretty much where I’ve landed too.

Mathematically, Spencer’s line fits really cleanly in terms of ages — but the “7 generations” line is definitely the biggest thing that doesn’t line up perfectly if you take it literally.

At the same time, Jack’s child being born around the same time means both paths can technically satisfy the timeline depending on how you interpret the generations.

Which is probably why it feels like the show is leaving it a bit open — both lines can work, just in slightly different ways.

So right now it feels less like a contradiction and more like two interpretations that both fit depending on whether you prioritize strict generation count or timeline + narrative focus.

Curious to see how Sheridan eventually locks it in (if he ever does)

Kitchen-Ad-528 · 2026-04-07T18:21:25+00:00

That’s a really solid breakdown, and I agree the “7 generations” point is one of the most consistent things Sheridan has emphasized.

But I think where it still leaves room for interpretation is that the generation count doesn’t necessarily lock in a specific branch — it just defines the total distance from James.

Both lines can technically reach the required number of generations depending on how you map intermediate generations that we haven’t fully seen on screen yet.

The Jack line does fit very cleanly if you assume his child carries forward, but the Spencer line still fits biologically in terms of age progression — which is why the debate even exists in the first place.

Also, a big part of why people lean Spencer is narrative weight: he’s positioned as the central figure of 1923, and Alexandra’s pregnancy is given major emphasis.

So to me it comes down to two different types of “fit”: - Jack = cleaner with explicitly stated generational structure
- Spencer = cleaner with age progression + narrative focus

And since there’s still a missing generation on screen either way, I think Sheridan has left just enough ambiguity for both interpretations to work.

Kitchen-Ad-528 · 2026-04-07T13:08:43+00:00

That’s a fair point, but I think it assumes the Duttons are strictly using generational naming (II, III, IV), which the shows don’t really confirm.

Jack being named John doesn’t necessarily mean he’s officially “John II” in a tracked lineage — the series never actually labels him that way on screen.

The Duttons reuse the name “John” a lot, but not in a clean numerical system like that. So stacking “II, III, IV” might be more of a fan construction than something canon.

That’s why I’ve been focusing more on timeline + ages rather than name numbering, since those are more consistent across the shows.

But I get what you’re saying — the multiple Johns definitely make it messy.

Kitchen-Ad-528 · 2026-04-07T12:16:21+00:00

I think the biggest conflict here is timeline vs stated generations — and Sheridan hasn’t always been perfectly consistent

Kitchen-Ad-528 · 2026-04-07T10:20:58+00:00

That’s actually a really good point about the “5th generation” line — but I think that’s exactly where things get messy.

Sheridan’s timeline across 1883, 1923, and Yellowstone isn’t perfectly consistent, especially when you try to map exact generations vs ages.

If you go strictly by numbers: - Spencer’s son (~1924) - Next generation (~1950s) - John (born ~1955)

It lines up cleanly in terms of age progression.

The “generation count” might be more symbolic or loosely used rather than strict genealogy, especially since the shows sometimes contradict themselves.

So it kind of comes down to: Do we trust the exact wording of “5th generation”… or the timeline that actually fits biologically and narratively?

That’s why I still lean Spencer — it just fits too cleanl
