Detailed family tree maker

An advanced family tree, with every detail that matters

Names and dates are where a family tree starts. A genogram, the advanced version of a family tree, adds the marriages, health history, relationships and households that explain the family. Add as many or as few layers as you need.

Quick answer

A detailed family tree records more than who descends from whom: marriages and divorces with dates, health conditions, how people get along, adoption and step relationships, and who lives together. The standard format for that is a genogram. GenogramAI is a free online detailed family tree maker: draw by hand or describe the family to the AI, then switch layers on and off as needed.

What makes a family tree detailed?

A basic family tree answers one question: who is related to whom. It is a chart of descent, and every line means either “married to” or “child of.” That is enough for a lot of purposes, and it breaks down quickly when a family has a second marriage, an adoption, a pattern of heart disease, or two siblings who have not spoken in twenty years.

An advanced family tree keeps the same layout and adds information in standardized layers. The notation comes from clinical practice, where it has been used for decades to record family structure and relationships. You don't need to know it: pick “divorced” or “close” and the editor draws the right line. The full comparison is in genogram vs family tree.

The same kind of family, at two levels of detail

Both are three generations: grandparents, their children and partners, and grandchildren. The first is a plain family tree. The second adds health conditions, closeness and conflict, the details a family actually talks about.

Genogram example: Basic 3-Generation Template — A plain family tree: names, birth years, ages, marriages and children. Open this example

Genogram example: Three-Generation Household — A detailed family tree of a three-generation household: the same structure plus medical quadrants and close, fused, conflict and distant lines. Open this example

In the second chart you can see at a glance that the grandfather has hypertension and type 2 diabetes, that anxiety appears in both his son and his eldest granddaughter, that she is close to her grandmother and her aunt, and that she and her grandfather are in conflict. None of that fits on a plain tree, and all of it matters to the family.

Every layer you can add

Partnerships with dates

Married, engaged, living together, separated, divorced, widowed, each with its own line and year. Multiple marriages sit side by side in order.

Health history

Conditions appear as colored quadrants on each person, with a key. Causes of death and ages at diagnosis go in the person’s details.

Emotional relationships

39 line types between any two people: close, distant, conflict, cutoff, fused, estranged, caretaker and more.

How children joined the family

Biological, adopted, foster and stepchild lines, plus surrogate and donor markings and twins.

Households

A boundary around the people who live together, for split custody, multigenerational homes or kinship care.

Heritage and place

Cultural heritage fill patterns, religion, education, social class and location views.

Time

A Time view with a year slider shows the family as it was in any year: who was alive, who was married to whom.

Notes and labels

Occupations, nicknames, maiden names and anything else in each person’s details and labels.

All of it is optional

Layers are switched on and off in the Views menu, so one detailed tree can still print as a simple family tree chart.

How much detail do you need?

Pick by purpose. Most trees need one or two extra layers, not all of them.

Purpose	Essential details	Worth adding
Genealogy or family history	Dates, places, maiden names, multiple marriages	Location and heritage views, Time view
Medical or genetic history	Health conditions, ages at diagnosis, causes of death	Medical quadrants with a key
Blended or adoptive family	Divorce and remarriage, step, adopted and foster links	Households, closeness lines
School project	Three generations, names, birth years	Birthplaces and a fact per person
Therapy or a class assignment	Three generations, emotional relationships, patterns	Medical, households, notes
Fiction and worldbuilding	Marriages, heirs, deaths	Affairs, feuds, secret parentage

Guides for each: genealogy, medical family history, blended families, adoption, school projects, class assignments and fiction.

Frequently asked questions

What is a detailed family tree called?

A family tree that records relationships, health and life events as well as names is called a genogram. It keeps the family tree layout (generations in rows, couples joined by a line, children below) and adds standardized symbols for marriages and divorces, medical conditions, emotional relationships, adoption and households. Genograms are used in family therapy, social work, nursing and medicine, and by families who want more than names.

What details can I add to a family tree?

In GenogramAI: birth and death years, ages, causes of death, marriage, separation and divorce with dates, living together and engagement, adopted, foster and stepchild links, twins, health conditions shown as colored quadrants, 39 kinds of emotional relationship, households, cultural heritage, religion, education, location and free-text notes. Every layer is optional.

Is a detailed family tree maker free?

Yes, to start. The free plan includes 2 trees with up to 50 people each, all 64 relationship types, medical quadrants, cultural patterns, 5 AI credits a month and PNG export, with no card. Professional ($12/month or $99/year) adds up to 25 trees, unlimited people and AI, file import, and PDF, SVG and GEDCOM export.

Does it search records or DNA like a genealogy site?

No. GenogramAI is a diagram tool, not a records database: there is no census search, record hints or DNA matching. If you already have research in genealogy software, export a GEDCOM file and import it (paid plans), then add the layers a genealogy program does not draw.

Will a detailed family tree get too cluttered to read?

It can, which is why the layers are switchable. The Views menu turns medical shading, heritage, households and other layers on and off, so you can keep one detailed tree and show a simple version when that is all you need. Emotional lines are best added only where they explain something.
