What this guide covers
This guide is a working reference for clinicians, students, and anyone using genograms in practice. The chapters below cover the standardized symbol set, step-by-step construction, the major specialty variants (medical, cultural, therapeutic), the theory genograms grew out of (Bowen family systems), and the software tools used to draw them. If you would rather learn by doing, you can build a genogram free online and follow along as you read. Use the section selector above or the chapter cards below to jump to whichever part is most useful for you right now.

A family tree traces lineage, names, and dates. A genogram is a clinical assessment tool - it captures the quality of relationships, emotional bonds, and health patterns within a family system.
| Feature | Genogram | Family Tree |
|---|---|---|
| Scope | Emotional, medical, and structural relationships | Lineage, ancestry, and descent |
| Symbols | Standardized shapes and line patterns | Informal boxes and connecting lines |
| Relationships shown | Couple types, emotional bonds, parent-child links | Parent-child and marriage |
| Primary purpose | Clinical assessment and pattern identification | Genealogical record-keeping |
| Typical depth | 3 generations (focused) | Many generations (broad) |
| Used by | Therapists, social workers, medical professionals | Genealogists, families, historians |
What Does a Genogram Include?
A genogram uses a standardized visual language to represent different aspects of a family system.
Person Symbols
Squares for males, circles for females, diamonds for unknown gender or pets, and an inner triangle for LGBTQ+ orientation.
Relationship Lines
Lines between partners showing marriage, divorce, cohabitation, and other couple types.
Emotional Bonds
Colored line patterns showing closeness, conflict, enmeshment, cutoff, and more.
Medical Conditions
Fill patterns and colors within person symbols to indicate health conditions.
Life Events
Birth, death, miscarriage, and pregnancy indicators with dates and annotations.
Parent-Child Links
Solid, dashed, and dotted lines showing biological, adoptive, and foster relationships.
What Does a Genogram Help You See?
The value of a genogram is not that it stores family facts in one place. It makes patterns visible: not just "there was a divorce" but "divorce appears in the same position across two generations," not just "heart disease runs in the family" but "early-onset cardiac events cluster on one side of the family." When names, dates, relationship lines, and annotations sit on one page, information that feels fragmented in conversation becomes structured enough to interpret.
History of Genograms
Murray Bowen developed the first family diagrams in the 1960s at the National Institute of Mental Health. He observed emotional patterns repeating across generations and needed a visual method for documenting them, which led to the earliest form of what we now call the genogram.
Monica McGoldrick and Randy Gerson standardized the notation in their 1985 book, Genograms in Family Assessment. They established the conventions still used today - squares for males, circles for females, specific line patterns for different relationship types, and methods for recording medical and emotional information.
The notation has since expanded to cover dozens of relationship subtypes, and software has replaced the hand-drawn diagrams of earlier decades.
Who Uses Genograms?
Genograms are used across a range of professional fields, each bringing its own focus:
Family Therapy
Therapists identify transgenerational patterns of conflict, enmeshment, addiction, and emotional cutoff. A couple's "communication problem" may mirror the same cutoff pattern in both partners' families of origin - a connection talk therapy alone rarely surfaces.
Social Work
Social workers use genograms for assessment, case management, and mapping support networks. During intake, a genogram may show that a child's behavioral issues at school coincide with a three-generation pattern of parental absence at the same developmental stage.
Nursing & Medical
Nurses and physicians record family health histories and identify hereditary risk factors. A medical genogram showing early-onset cardiac events clustered on one side of the family can prompt targeted screening a decade earlier than standard guidelines suggest.
School Counseling
School counselors map a student's family context to identify sources of stress. A student's anxiety may coincide with a recent divorce that replays the same separation pattern their parent experienced at the same age.
Genetic Counseling
Genetic counselors use pedigree diagrams closely related to genograms to assess hereditary conditions. A pedigree showing autosomal dominant inheritance across four generations makes the case for genetic testing concrete and compelling.
Career Counseling
Career counselors explore how family work values and vocational expectations influence a client's choices. A career genogram may reveal that chronic job dissatisfaction stems from pursuing a family-expected profession rather than the client's own aptitudes.
What a Genogram Cannot Tell You on Its Own
A genogram reveals patterns, but it does not explain them. A cutoff line between father and son could reflect abuse, an inheritance dispute, immigration, or a family rule that nobody questions. The diagram raises the question; the clinician still has to pursue the answer.
Family information is often incomplete, disputed, or filtered through a single person's perspective. Dates may be vague, diagnoses misremembered, and the quality of a relationship may look quite different depending on which family member you consult. For these reasons, most clinicians treat the genogram as a working map that evolves over time rather than as a document that proves anything on its own.
