There is a moment in the life of every large family when someone looks around a gathering and quietly grieves. The cousins no longer all know each other's children. Two branches have not spoken since the land was divided. The grandchildren in London and Atlanta follow the family group chat in a language they read better than they speak. And the person grieving draws the obvious conclusion: we are falling apart. What our grandparents held together, we are losing.
Dennis T. Jaffe's Borrowed from Your Grandchildren: The Evolution of 100-Year Family Enterprises (Wiley, 2020) exists to file a correction against that conclusion, and the correction begins with an odd fact about the research field itself. The academic study of family business, born in the 1980s, produced models for the first generation, the second, and the third, and then simply stopped. Jaffe puts the gap in one blunt question: "The family business literature and its key models describe generations one, two, and three, but descriptions stop there. Whither the fourth generation?" Everyone assumed the story ends at the third generation, because the old proverb, told on every continent in some form, says the first builds, the second holds, and the third squanders. So nobody studied what comes after.
Jaffe studied what comes after. Over six years, his team at Wise Counsel Research interviewed leaders from just over 100 family enterprises worldwide that had kept a shared family identity across three or more generations. In this group, 62 percent have control and leadership in the fourth generation or later, and because each family could look back across its whole history, the respondents reported on more than 250 generational transitions between them. It is, to his knowledge, the first real study of the families on the far side of the cliff everyone else treats as the edge of the map.
Honesty requires the frame before the findings. These are not ordinary families. To enter the study a family had to clear $250 million in revenue or its equivalent; the median family is worth around $700 million, and together the families control resources well in excess of $100 billion, which Jaffe compares to the annual GDP of a small country. They are 62 percent North American, the rest mostly European, Asian, and Middle Eastern. There is no African family in the sample, and Jaffe concedes the sample "is not large enough or random enough to draw any conclusions." What survives that caveat is not the percentages. It is the developmental map, because the stages he describes are driven by arithmetic and geography, and arithmetic and geography do not check your net worth.
Here is the one idea this essay carries. A family struggling after the third generation is not necessarily decaying. It is usually molting: outgrowing the form of a household and being forced to become something else, a deliberate community Jaffe calls a tribe, and the strain everyone reads as falling apart is the labor of that becoming.
Jaffe's map has four stages, and the names alone reframe the grief. After the founding generation, the second stage he calls Collaborating Siblings: a handful of brothers and sisters who grew up in one house, deciding to remain partners. The third he calls the Emergence of a Cousins' Community: now the owners are cousins from different branches, raised in different households, holding what he calls a dual allegiance to their own branch and to the extended family. The fourth stage is Business Renewal and Family Reengagement, and beyond it lies the stage he names with a deliberately tribal phrase: the "Tribal" Extended Family, many relatives, dispersed, with the family and the business now clearly distinct things that must each be sustained on purpose.
The arithmetic underneath the map is merciless and universal. In the third generation, the families in his study averaged about forty living members. By the fourth generation and later, the average was 130. No household on earth holds 130 people. No dinner table, no single matriarch's authority, no unspoken understanding formed in one kitchen can stretch that far. This is why the third-to-fourth transition breaks so many families: they attempt to run a nation on the operating system of a household, and when it fails they conclude the love has died, when in fact only the format has.
The siblings never needed to build trust; they were issued it at birth, in a shared bedroom. The cousins have less of it. The fourth generation, scattered across cities and countries, may have almost none. That is not a moral failure. It is what the map predicts.
The pivot of Jaffe's argument is a sentence that families in the thick of the strain should write out and pin somewhere visible. Once a family has a shared heritage but no longer a shared location, he writes, relationships and trust "do not grow spontaneously. They have to be created." Tribes grow naturally when related families share a village, a livelihood, a daily life. Remove the village and the tribe must be built: times and places for shared experience deliberately made, meaning and purpose for the bond deliberately articulated, each new generation deliberately woven in.
Jaffe reaches back to the sociologist Thorstein Veblen, writing in 1899, for the observation that "The wealthy are the most tribal group in modern society." It sounds like a jab at dynasties, and partly it is. But inside this book it reads as a description of technique. The families that keep fortunes together behave tribally on purpose: they hold councils, run rituals, tell origin stories, initiate the young, and treat membership as something conferred and renewed rather than merely genetic. The generative families in the study, Jaffe reports, actively and consciously work to establish community, renewing the ties with every generation's new members, precisely because nothing renews them automatically.
When his team asked these families what actually kept them together, the answers clustered into six qualities, and the ranking matters: shared values and core purpose came first in every interview, ahead of cross-generational engagement, business resiliency, governance structures, education of the rising generation, and commitment to community beyond the family. Structures came fourth. Money, notice, is not on the list at all. The glue is a story about who we are and why we stay, held in common, and everything else is scaffolding around it.
Everything above was learned from families with family offices and nine-figure balance sheets, and the book's mechanisms, professional family presidents, private trust companies, annual assemblies with budgets, assume that scale. The book stops there. We go one step further, and this section is our translation, ours alone, into the families we write for.
An African reader meets Jaffe's tribe language with a certain irony, because the extended family he describes as an exotic achievement is simply how most of our families already understand themselves. The clan, the lineage, the totem, the village association: our cultures never shrank the family to a nuclear household in the first place. In one sense Jaffe's 1-percenters spent millions rediscovering what a Ugandan kwanjula, the traditional introduction ceremony that formally binds two extended families, has always assumed: that a family is a community of branches with rituals, elders, and a shared story, not four people and a television.
But the irony should not become complacency, because the force that broke Jaffe's families is now working on ours, faster. Migration to Nairobi, Johannesburg, London, Houston. Children raised on three continents. The village that made tribal trust automatic is emptying, and the rituals that renewed membership are being attended by video call, if at all. The African family of 2026 is running the exact experiment Jaffe documented: shared heritage, vanishing shared location. His finding lands on us with full force. The trust our grandparents inherited from proximity, our grandchildren will only have if someone manufactures it.
And here we can be more honest than nostalgia usually allows. The traditional structures were real, but they ran on assumptions that are gone: that members stayed put, that authority flowed by age alone, that daughters' children belonged elsewhere, that no one would ever need the records written down because the elders were the records. The work is not to reenact the old tribe. It is to do what Jaffe's families did: keep the values, rebuild the mechanism. A family council with an agenda and minutes is not a Western imposition on African family life. It is the clan meeting, given a form that survives dispersion. A written family story is the fireside genealogy, given a form a child in Toronto can inherit.
Put the map and the translation together and the grief from this essay's first paragraph resolves into an assignment. The family that no longer fits in one compound has not failed. It has arrived at the stage where a second founding is required: not of a business this time, but of the family itself as an institution. The first founder built an enterprise with their hands. The third and fourth generations must build the tribe with equal deliberateness, and Jaffe's study says the ones who do are not the exception that proves decline; they are proof that the proverb about the third generation is a warning, not a law. He named the myth directly: the belief that decline by the third generation is predestined is the first of five myths his data dismantles.
So the practical work looks unheroic. Decide that the extended family will meet, and fix the rhythm before fixing the venue. Name the shared story: where we began, what we survived, what we hold. Give the young a role that is real, not decorative, because a tribe that initiates no one is one funeral away from being a rumor. Write the membership down, all of it, both lineages, the branches abroad, the children who have never seen the home village, because in a dispersed family the unrecorded member is the first one lost.
That last task is where the Family Tree in LegacyPot earns its place in this story: a single shared map of every branch, every marriage, every child on every continent, so that the tribe's first artifact, the knowledge of who belongs, no longer lives only in the memory of one aging aunt.
Here is the one thing to do this month. Convene nothing. First, count. Sit down, alone or with one elder, and list every living member of your extended family: every branch, every household, every country. Most people from large families have never once seen the whole number. If it surprises you, and it will, let the surprise do its work: you are not a household anymore, and you have been trying to run one.
Then share the list with the family, in your Family Tree, and ask the question that turns a lineage into a tribe: what do we do, on purpose, every year, that a member in any country can belong to? One gathering with a fixed season. One story told the same way to every child. One decision made in council rather than in one kitchen. Jaffe's hundred families, with all their billions, discovered nothing more sophisticated than that. The trust of the village, once the village is gone, has to be created. The families still standing after a hundred years are simply the ones who accepted the assignment.
