What is a Genogram?
A genogram is a graphic representation of a family system that maps relationships, medical history, and emotional patterns across multiple generations using standardized McGoldrick-Gerson-Petry clinical notation.
Developed by Monica McGoldrick and Randy Gerson in 1985, genograms go far beyond family trees by documenting emotional bonds (close, conflicted, distant, cutoff), health conditions, behavioral patterns, and cultural context. They are used by marriage and family therapists, social workers, physicians, genetic counselors, and students in over 300 graduate programs worldwide. Tools like GenogramAI now use AI to generate genograms from plain-text descriptions.
Genogram Definition
A genogram (pronounced JEN-o-gram) is a pictorial display of a person's family relationships and medical history. It goes beyond a traditional family tree by using standardized symbols to show not just who is related to whom, but also the nature and quality of those relationships.
First developed in the 1980s by family therapists Monica McGoldrick and Randy Gerson, genograms have become essential tools in family therapy, genetic counseling, and clinical practice. Today, a genogram maker can help practitioners and families visualize complex patterns that might otherwise remain hidden.
"The genogram is a form of family mapping that has become the standard assessment tool for family therapists, providing a rich source of hypotheses about how clinical problems may be connected to the family context and the evolution of both problem and context over time."— McGoldrick, Gerson, & Petry, Genograms: Assessment and Treatment, 4th ed. (W.W. Norton, 2020)
Key Takeaway
A genogram is like a family tree with superpowers—it shows relationships, medical patterns, emotional bonds, and multigenerational dynamics all in one visual diagram.
Genogram vs Family Tree: What's the Difference?

Frequently Asked Questions About Genograms
What is a genogram?
A genogram is a graphical representation of a family tree that displays detailed information about relationships, medical history, emotional patterns, and other family dynamics across multiple generations. Unlike simple family trees, genograms use standardized symbols to show the quality of relationships, health conditions, and behavioral patterns.
What is the difference between a genogram and a family tree?
While both show family relationships, a genogram includes much more detail. Family trees show biological connections (who is related to whom), while genograms add relationship quality (close, distant, conflictual), medical history, emotional patterns, divorces, remarriages, and other clinical information using standardized symbols.
Who uses genograms?
Genograms are used by family therapists, marriage counselors, social workers, physicians (especially genetic counselors), psychiatrists, nurses, and researchers. They're also valuable for individuals exploring their family history or understanding multigenerational patterns.
What are genogram symbols?
Genogram symbols are standardized shapes and lines: squares for males, circles for females, diamonds for unknown gender. Relationship lines show marriages (solid), divorces (double slash), and emotional bonds (various patterns for close, distant, conflictual relationships). Additional symbols indicate deceased individuals, medical conditions, and life events.
How many generations should a genogram include?
A typical genogram includes three generations — see our 3 generation genogram guide for details. It covers the identified person (index person), their parents, and their grandparents. However, genograms can include more generations if relevant patterns extend further back, or fewer if information is limited.
What are the 5 components of a genogram?
The five core components of a genogram are: (1) Person symbols — squares for males, circles for females, diamonds for unknown gender; (2) Structural relationships — horizontal lines showing marriages, separations, and divorces; (3) Parent-child connections — vertical lines linking parents to children, including adopted and foster links; (4) Emotional relationship overlays — patterned lines showing closeness, conflict, cutoff, enmeshment, and other dynamics; and (5) Contextual annotations — medical conditions, mental health history, substance use, cultural heritage, and significant life events.
How do you make a genogram step by step?
To make a genogram: (1) Gather family information for at least three generations, (2) Draw the index person in the center using the correct gender symbol, (3) Add family members with squares, circles, or diamonds, (4) Connect them with structural relationship lines (marriage, divorce, children), (5) Layer in emotional relationship overlays (close, distant, conflictual), (6) Annotate medical history, mental health, and life events, and (7) Review for accuracy. You can use an AI-powered genogram maker like GenogramAI to create one in minutes.
Is there a free genogram maker?
Yes. GenogramAI offers a free online genogram maker that supports all 150+ standard symbols, emotional relationship overlays, medical annotations, and AI-assisted generation from text descriptions. No download is required — you can create, edit, and export professional genograms as PNG, PDF, or JSON directly in your browser.
