Learn How to Create a Genogram for Your Family

Understanding What a Genogram Is and Why It Matters

A genogram is a visual map of your family tree that goes beyond simple names and dates. While a traditional family tree shows who is related to whom, a genogram includes additional information about relationships, health patterns, behaviors, and significant life events. Think of it as a detailed family history diagram that tells the story of your family across multiple generations.

The word "genogram" combines "genealogy" (family history) and "gram" (a written record or diagram). Mental health professionals, social workers, and medical practitioners often use genograms to understand family patterns and dynamics. However, genograms are equally valuable for personal use. They help you see connections between family members that might not be obvious, understand inherited traits or health conditions, recognize behavioral patterns, and preserve family history for future generations.

Genograms typically include three or more generations of a family. They show biological relationships, marriages, divorces, and sometimes friendships or close relationships that function like family bonds. Many genograms also include information about significant health conditions, major life events, occupations, and emotional distances or closeness between family members.

Creating a genogram can be enlightening. You might discover that a health condition runs through your family line, understand why certain family dynamics exist, or find patterns in how family members handle challenges. Parents might use genograms to explain family structure to children. Individuals researching their heritage can use genograms to organize information they have gathered. People dealing with family challenges might use genograms to visualize relationships more clearly.

Practical takeaway: Before you begin, decide your purpose for creating a genogram. Are you documenting family health history? Preserving your family story? Understanding family relationships? Your purpose will guide which information you include and how detailed your genogram becomes.

Gathering Information from Family Members

The foundation of an accurate genogram is information gathering. You will need to collect data from relatives who can provide details about your family history. This process requires planning, sensitivity, and patience. Not all family members will be comfortable sharing certain information, and that is acceptable. Respect boundaries while gathering what you can.

Start by identifying which relatives have knowledge about your family history. Older family members often hold the most detailed information about previous generations. However, younger family members might have current information about cousins, siblings, and their own children that you need. Consider reaching out to multiple family members, as different people remember different details and may have varying perspectives on family history.

When contacting relatives, explain what you are doing and why. A simple message might be: "I am creating a family tree diagram that includes health history and major life events. Would you be willing to share some information about our family?" Most people are happy to help when they understand the purpose. You might conduct conversations in person, over the phone, through video calls, or via email, depending on what works best for your family.

Here are the main categories of information to gather:

• Names (including maiden names, nicknames, and name changes)
• Birth dates and death dates
• Marriage dates and, if applicable, divorce dates
• Current location or last known location
• Occupation or profession
• Significant health conditions or causes of death
• Education level
• Major life events or accomplishments
• Current relationships and emotional closeness between family members
• Substance use history if relevant to your purposes
• Mental health history if your family is open about it

Be sensitive when asking about difficult topics like addiction, mental illness, or family conflicts. You might phrase questions carefully: "Has anyone in the family dealt with depression or anxiety?" rather than "Who is crazy in the family?" Create a document or spreadsheet to record the information as you gather it. Include the date you gathered the information and which family member provided it, as this helps you track sources and note if you need to verify details.

Practical takeaway: Create a simple information sheet you can send to family members with blanks for the categories you need. This makes it easier for relatives to provide information without lengthy conversations, and you will receive consistent data across family members.

Learning the Symbols and Conventions Used in Genograms

Genograms use specific symbols and visual conventions so that anyone looking at your diagram can understand the information quickly. Learning these symbols is essential before you start drawing. The good news is that the symbols are straightforward and logical once you see them a few times.

In genogram notation, basic shapes represent people and their gender. A square represents a male or man. A circle represents a female or woman. A triangle represents a person whose gender is unknown or not specified. Horizontal lines connect people in a relationship. A solid horizontal line indicates a marriage or committed partnership. A dotted or dashed line represents a non-married partnership or relationship. When a marriage ends in divorce, the horizontal line between two people is broken or marked with a slash.

Vertical lines connect parents to their children. A horizontal line called a sibship line connects all the children of a couple, and vertical lines drop down from this line to each child. Birth order matters in genograms—children are typically arranged from left to right, oldest to youngest. If a child is adopted, this might be noted on the diagram with an "A" or by using a different line style.

Colors or notes can indicate health conditions or other information. For example, a shaded or colored square might represent a male with a particular health condition, while an unshaded square represents a male without that condition. You create a legend for your genogram explaining what each color or marking means.

Here are common notations and their meanings:

• Horizontal line between two shapes = marriage or partnership
• Broken or slashed line = divorce or separation
• Vertical line from couple = their children
• Horizontal line connecting children = sibship line
• Double lines = very close or enmeshed relationship
• Dotted line = distant relationship
• Zigzag line = conflict or hostility
• Shading or color = indicates a health condition or trait (you define this in a legend)
• X through a shape = deceased person
• Question mark = unknown information

Different genogram creators adapt these symbols based on their needs. Some use computer software that has built-in symbols. Others draw by hand using their own variations. The key is consistency—establish your symbols and meanings at the beginning, create a clear legend, and stick with them throughout your diagram.

Practical takeaway: Before you start your genogram, draw or print a reference sheet with all the symbols you plan to use and their meanings. Keep this reference sheet nearby as you work so you maintain consistency throughout your diagram.

Choosing Tools and Methods for Creating Your Genogram

You have several options for creating a genogram, ranging from pencil and paper to specialized software. Your choice depends on your comfort with technology, how detailed you want the diagram to be, and whether you plan to share it with others or update it over time.

The simplest method is drawing by hand on large paper. This approach requires only paper, pencil, and an eraser. It is excellent for initial drafts or if you prefer a personal, handmade feel. The disadvantage is that hand-drawn genograms can be difficult to modify if you make mistakes or want to add information later. Large paper (like 11x17 inch tabloid paper) works better than standard letter-size paper because genograms can become quite large.

Microsoft Word and similar word processors work well for simple genograms. These programs have shape-drawing tools that let you create squares, circles, and lines. You can type names and information inside the shapes and move elements around easily. This method is accessible to most people and produces a clean, readable document. The limitation is that complex family structures with many generations can become cluttered.

Spreadsheet programs like Microsoft Excel or Google Sheets offer another option. Some people create genograms in spreadsheet format, using cells to organize family members by generation. This works particularly well if you are gathering extensive information and want to keep data organized before creating a visual diagram.
