Just as genealogists use family trees to visually document legal relationships, doctors, therapists and many other professionals use a similar method to diagram relationship structures. The genogram resembles a family tree, but uses a standard set of symbols and line types to denote various relationships, depending on the genogram's purpose. For instance, a physician may use a genogram to visually map genetic disorders among one family, while a therapist is interested in emotional relationships between family members and other significant people. Generally, a genogram shows three generations. You can draw your own genogram, use a free online tool or download free genogram software.
Draw Your Own
Print a diagram sheet of the standard genogram symbology (see Resources).
Write the name of your index person (yourself or another person of interest) and draw a circle around a female name or a square around a male name.
Draw a square and a circle in a row above the index person. Write the father's name in the square and the mother's name in the circle.
Draw a line connecting the parents. Decide which line type describes the relationship between the parents. For instance, a solid straight line joining the two denotes a normal relationship. A line with two hatch marks denotes a divorce. Consult your symbol guide sheet for the various line types.
Draw a line connecting the index person and each parent. Choose line types that denote each emotional relationship.
Continue adding grandparents, great-grandparents, spouses, siblings or children, depending on the relevancy of the individuals for your purpose.
