Genogram vs. Family Tree — What Is the Difference?

At first glance, a genogram and a family tree look like the same thing. Both map relatives across generations, both use connecting lines to show who is related to whom, and both start with a central individual or couple. But the similarities stop there. The purpose, the information included, and the conclusions you can draw are fundamentally different.

What a Family Tree Does

A family tree is primarily a genealogical record. Its purpose is to document biological and legal descent: who are this person's ancestors, and who are their descendants? A classic family tree contains names, birth and death dates, places of origin, and sometimes occupations or marriage dates.

Family trees are created for historical and personal interest — tracing ancestry, connecting with distant relatives, preserving family heritage. They answer the question: where do I come from?

What a Genogram Does

A genogram is a clinical assessment tool. Its purpose is to map not just who the family members are, but how they relate to each other and what patterns exist across generations. In addition to structural information, a genogram records:

• Emotional relationship quality between any two individuals (close, conflictual, estranged, enmeshed).
• Medical and psychiatric history: chronic illness, addictions, mental health diagnoses.
• Critical life events and their timing: migrations, job losses, deaths, serious accidents.
• Repetitive behavioural patterns: divorce rates, career patterns, substance use, caregiver roles.

A genogram answers a different question: what patterns does this family carry, and how do they affect the individual in front of me?

Key Differences at a Glance

Aspect	Family Tree	Genogram
Primary purpose	Genealogical record	Clinical / therapeutic assessment
Relationship quality	Not included	Central component
Medical history	Rarely included	Systematically recorded
Depth (generations)	Can span many generations	Typically 3 generations
Symbol set	Varies widely	Standardised (McGoldrick system)
Who uses it	Genealogists, families	Therapists, social workers, physicians

Can They Overlap?

Yes. A medical genogram is sometimes used in a genealogical context to track hereditary conditions across a large family. Conversely, a thorough family tree with annotated life events can provide useful background for a genogram created in a clinical context. But they are different tools built for different purposes, and using a family tree where a genogram is needed — or vice versa — will leave important information either hidden or inaccessible.

Which One Do You Need?

• Use a family tree if your goal is genealogy, heritage, or tracing ancestry over many generations.
• Use a genogram if your goal is clinical assessment, therapeutic exploration, social work intake, or understanding the relational and health context of a specific individual or family.

If you need a genogram, WinGeno covers the structural layer of a genogram — partner relationships (married, divorced, cohabiting), child connections (biological, adopted, foster), birth and death dates, and the identified person marker — all stored locally, no account required.
