One session, three generations: why a family story needs the longer format

“Couldn’t we do this in an hour?” I understand the question and I have an honest answer to it: we could, but something different would come out of it. In an hour we would draw a family tree. In ninety minutes something else happens — the story takes on a shape, and in that shape you actually see it.

The “A Look into the Past” session lasts an hour and a half and covers three generations. Both numbers were chosen for a reason, and the two reasons are connected: a family story needs range in order to become visible, and it needs time so that this range can be walked in one piece.

In this post I explain why the longer format is not a luxury but a condition; what only shows up once you put three generations on a single sheet; why one continuous session works differently from the same material broken up over six weeks; and how this differs from the regular therapeutic process — which it does not replace, but complements.

Half an hour for a hundred years

Let’s look at what “three generations” actually means. If you are forty today, your parents were born somewhere around the nineteen-seventies and your grandparents somewhere around the middle of the century or earlier. So a hundred years end up on a single sheet of paper: wars, migrations, poverty and sudden prosperity, moves from village to city, divorces that were once a disgrace and are ordinary today, children who died and children who survived.

A hundred years does not fit into half an hour. Not because there is too much data — the skeleton of a genogram really could be drawn quickly — but because the data is not the point. The point is what shows up between the data.

A short format forces listing. Someone gives names, years, occupations, and leaves with a correct table that tells them nothing they did not already know. A longer format allows the account to wander — and with a family story, wandering is the main road, not a side path. When, in the middle of talking about your father, you suddenly say something about his brother, the one who left and never came back, what opens up is often precisely the thing you came for.

And there is more: emotional rhythm has its own tempo. The body spends the first fifteen minutes working out that it is safe. If a session has fifty minutes, thirty are left for the real work — and just as something opens up, it would be time to finish. That is not a format, that is an interruption.

At this point many people object: I know my own family, what could possibly take an hour and a half here. The answer is that you know its story — the one told at holidays, the one that has a settled shape. What takes an hour and a half is getting past that settled shape. Family accounts are polished: we repeat them for so long that they turn smooth, and smooth accounts reveal nothing new. Only when you write them down on paper and put a year next to each person does the smooth account catch on the facts — and it is precisely those catches that are interesting.

What an eye that looks at three generations sees

Now to the second part: why three generations and not just the family you grew up in.

Murray Bowen, the father of the systemic view of the family, described a process we call multigenerational transmission: the emotional solutions one generation develops are passed on — not as a conscious instruction, but as a default setting that the next generation accepts as “that’s just how it is”. If you look at this within one generation, it looks like personality. If you look across three, it shows up as a line.

Concretely: a woman who takes on all the responsibility in every relationship and wears herself out will say about herself that she is simply like that. When she sees on the sheet that her mother did the same, and before her a grandmother who at thirty-three was left alone with four children, the description changes. It is no longer a personality trait. It is a survival strategy that once saved someone’s life — and was passed on, even though the danger has long since gone.

This shift is not cosmetic. Personality traits seem unchangeable; strategies can be looked at. I have written about the mechanism of transmission itself — psychological and also biological — in the post on intergenerational transmission, and about the emotional side in the post on emotional inheritance.

Comparing ages: the most powerful tool on the sheet

If I had to choose one single thing that the longer format makes possible, I would choose this: placing periods of life side by side.

On a genogram all the generations appear at once, which means you can compare things we never compare in everyday life. How old was your mother when you were born? And how old were you when your first child was born? What was happening in the family in the year your father turned the age you are now?

These questions have a particular effect. As long as your mother is “mother”, she is an adult figure without an age. When you work out on paper that she was twenty-three when you were born — and that at twenty-three you were still in the middle of your studies and in no way ready for a child — something in your relationship to her shifts. Not in the sense of excusing everything that happened. In the sense of understanding proportion.

The same goes for repeated coincidences: a separation at the same age as a parent went through one; sudden anxiety in exactly the year when someone in the previous generation was at a similar point in life; the decision to move at precisely the time when others moved too. We do not invent such coincidences — usually they are there on the paper in front of us and we simply read them.

Comparisons like this need room. If you spend half an hour just remembering the years, you never reach this stage.

Every generation lived in a different world

The third thing the range of three generations brings is context — and in a shorter conversation this is almost always lost.

When we write the years down on paper, time appears alongside the names all by itself. A grandmother who gave birth to her first child in 1958 did not have the same set of choices available to her as a woman giving birth today. Divorce meant something different. Leaving home meant something different. The word “depression” meant something different, or did not exist in the family’s vocabulary at all. What we now call coldness was often the only available way to survive losses that followed one another without a break.

This is not excusing. It is placing in context. And the difference between excusing and placing in context matters: excusing says “it wasn’t that bad”, placing in context says “it was bad, and now I can see what someone was acting out of when they acted the way they did”. The first closes the conversation, the second opens it.

This has a particular effect on people who grew up with very silent parents. When you see on the sheet how much your father lost before he turned twenty, his silence is suddenly no longer a personal rejection of you. It becomes something that was there before you. This shift often releases anger that for years could be neither expressed nor set down — I have written about the complicated relationship between anger and family history in the post on the child who was not allowed to be angry.

But context does not only work backwards. When you see the kind of world in which your ancestors made their decisions, it becomes easier to tell which of those decisions was an answer to the conditions of the time and which is genuinely a belief that you now carry on, inherited, into a world where it no longer applies at all.

Why one continuous session works differently

And now the most frequent question: why not work on the genogram gradually, half an hour at the start of each regular session, three weeks in a row? The material would appear to be the same.

It is not. And there are several reasons.

• Continuity of the account. A family story is a web, not a list. When you tell it in one piece, the connections are made as you go — something you say about your grandmother in the fortieth minute throws light on what you said about your father in the fifteenth. If there is a week in between, that bridge does not get built.
• Working memory has a limited capacity. Patterns show up when enough elements are “on the table” at once. Fragmented work means the context has to be built again each time — and there is no room left for the pattern.
• The emotional arc. Every session has its own arc: opening, work, closing. Three times thirty minutes means three openings and three closings — and three times as much energy spent on the periphery instead of the core.
• Tiredness is an ally. After an hour of concentrated attention, the polished, pre-prepared part of the telling gives way. What comes after that is often the most true. In a thirty-minute slot you never reach that point.
• The whole feels different. When you look at the entire sheet at once at the end, you experience your family as one thing. That experience cannot be added up out of three partial views.

The clinical literature on one-off, purposefully designed sessions supports this. A meta-analysis of single-session interventions showed that one well-structured session can produce measurable effects (Schleider and Weisz, 2017), and as far back as 1990 Moshe Talmon described how the most common number of visits at psychotherapy clinics is — one. Not always because people gave up. Often because it was enough.

What matters here is that a single session works when it is designed as a whole — with a clear beginning, core and conclusion. What does not work is therapy that accidentally ended after an hour. The difference lies in whether the ending is planned or incidental. The ninety-minute format is designed so that its ending is built in: the last ten minutes are not a remainder, they are part of the design.

What this is not: a substitute for therapy

Let me be completely clear here, because I do not want to promise more than the format can do.

A genogram session is not shortened therapy. It is a map. A map shows you where you are, where the paths run and where the drops are — but it does not walk the paths for you. Changing a pattern that has been built up over three generations does not happen in an hour and a half; it happens over months of work, in concrete relationships, in repeated small decisions. I write about this in the posts on what working on yourself means and on breaking the cycle of patterns.

So what does it give? Three things. First, understanding — and understanding in itself is a relief, because it takes away the guilt for something that was never only yours. Second, language — once a pattern has a name, you can notice it the next time it happens live. Third, a starting point — if you decide on regular work, we know where to begin, and we do not spend the first six hours getting to know the background.

It is only fair to mention one more limitation. A single look at three generations is necessarily selective: a few stories fit into an hour and a half, not all of them. What stays outside is not lost, it is simply not drawn — and if you later decide to continue, the sheet gets added to. Many people come back to their genogram a year or two later and find that they now see things that could not be seen the first time, because they themselves were in a different place.

That is exactly why many people use this session as an introduction. And exactly why for many others it is also enough on its own. I have worked through the criteria for both in the post on whether a genogram should be an introduction or a stand-alone experience.

Who this format particularly suits

From experience, a few groups have emerged for whom a longer one-off session turns out to be particularly suitable:

• People who “don’t know where to start”. If you feel that the whole thing is too tangled for a single sentence, a map is a better beginning than a conversation. I have covered a related theme in the post on not knowing where to start.
• Those who are currently in a transition. The birth of a child, the death of a parent, a move, retirement — in transitions the family past almost always speaks up more loudly.
• People who have already been in therapy and feel that something is missing. What is often missing is precisely the systemic layer: you understand yourself well, but not the field you came out of.
• Those who do not want a long process, or cannot manage one. For reasons of time, money or personal circumstance. Better one good session than none.
• Couples and adult siblings. Sometimes several people come and look at the same sheet — and discover that they grew up in two rather different families. More on this in the post on siblings and alliances.

One thing, though, applies to everyone listed: the format requires a willingness to look, not only to talk. Ninety minutes is long enough that at some point during the telling a place appears where it would be easier to change the subject. If you are willing to stay there a little longer, you will take considerably more away from the session than if you spend it in the safe telling of familiar stories. Nothing happens by force — but the difference between coming “to have a look” and coming “to find out” does show.

It is less suitable when you are in the middle of an acute crisis. Then you first need solid ground under your feet, and only afterwards the view.

How to arrange a session

The “A Look into the Past” session lasts ninety minutes and is described among my services. We arrange it through the contact page; before the session I ask you only what you are coming with, the paper does all the rest.

If you want to know what it looks like minute by minute, read the post on how a 90-minute session unfolds. And if you are more worried about whether you will know enough — in practice nobody has ever known too little. Those who knew the least often left with the most.
