Drawing a family tree turns names and relationships into a clear visual record. Before you begin, decide whose family the tree will show, how many generations to include, and whether it is for personal research, a school project, or sharing with relatives. Gather the information you already know, and mark uncertain details rather than filling gaps with guesses.
What You’ll Need
- Paper large enough for the number of people and generations you plan to include, or a digital drawing tool.
- Pencil and eraser for a first draft; a ruler can help make lines and boxes neat.
- Reliable family information, such as names, dates, and relationships. Ask relatives or consult family records when appropriate.
- Optional: colored pens, sticky notes, or a spreadsheet for organizing people before drawing.
Step-by-Step
- Choose the focus of the tree. Decide whether it will trace your own ancestry, show one relative’s family, or include descendants from a particular couple. A family tree can be drawn in more than one direction: ancestors usually appear above a starting person, while descendants appear below an ancestor. Choose one approach and keep it consistent.
- Set a manageable scope. Pick a starting person or couple and a number of generations to show. For example, a compact ancestry tree might show you, your parents, grandparents, and great-grandparents. If you want to include a large extended family, plan more space or make separate charts. There is no need to include every relative on the first version.
- Collect and organize the facts. Write each person’s name on a note or in a list, along with the relationship that connects them to the others. Add birth, marriage, and death dates only when known and useful. Check spellings and distinguish people with similar names using dates, locations, or middle names. Record where information came from, especially if it is uncertain or based on family recollection.
- Choose how to show relationships. A common layout uses one box or name label per person. Place partners side by side and connect them with a horizontal line; connect that line to their children with a vertical line and a horizontal sibling line. In an ancestry tree, put each generation above the next; in a descendant tree, put the older generation above the younger generations. A legend can explain any symbols or colors you use.
- Plan the page before drawing. Lightly sketch rows for generations and estimate how many people belong in each row. Center the starting person or couple, then leave room for branches on both sides. Use landscape paper for a wide family and portrait paper for a tree with more generations than branches. If the chart is too crowded, use a larger sheet, reduce optional details, or split it into linked pages.
- Draw the people and connections in pencil. Begin with the starting person or couple, then add parents, children, or other relatives according to your chosen direction. Keep each generation on its own row and use clear lines to connect people. Avoid drawing a line that makes a relationship ambiguous; if a family structure does not fit a simple partner-and-children layout, label the relationships in words instead of relying on symbols alone.
- Add names and optional details. Write names consistently and legibly. You might include birth and death years, places, or a short note, but avoid crowding the chart. Use a consistent date format, such as “1902–1981,” and leave a field blank or use “unknown” when a detail has not been established. Do not invent a date to make the chart look complete.
- Check every branch against your notes. Read the chart from person to person and confirm that each parent, child, and partner is connected as intended. Check that siblings share the correct parent connection and that no line accidentally joins unrelated branches. Ask a knowledgeable relative to review disputed or unclear details, while keeping disagreements visible as unresolved if they cannot be settled.
- Finish and preserve the chart. Erase planning marks, darken the final lines, and add a title, the date you made the tree, and a small note about its scope. If you share it, consider whether everyone named would be comfortable with personal details being circulated. Keep a digital copy or photograph so later corrections do not require recreating the whole tree.
Common Mistakes
- Starting too big: Trying to show every branch at once can make names unreadable. Start with a defined group, then make additional charts for extended relatives.
- Mixing directions or generations: If some ancestors are above the starting person and others below, readers may misread the connections. Decide on a layout first and label generations if needed.
- Assuming details are certain: Family stories, public records, and spellings can differ. Note the source or uncertainty rather than silently choosing one version.
- Using unclear lines or symbols: A decorative tree with branches may look attractive but obscure who is related to whom. Prioritize explicit connectors and a simple key.
- Leaving out complicated relationships without explanation: Adoption, remarriage, step-relations, guardianship, and donor or birth-parent information may not fit a basic chart. Use labels and a legend that reflect the family’s preferred wording.
- Sharing sensitive information casually: Living people may not want birth dates, family circumstances, or other personal details posted publicly. Ask before sharing and limit what the chart reveals.
Tips
- Use sticky notes or movable digital labels while planning; rearranging them is easier than redrawing a finished chart.
- Choose one spelling and naming style, and use it throughout. If a person used different names, include a familiar or alternate name in parentheses where helpful.
- Use color sparingly to distinguish branches or types of information, and include a key so color is not the only way to understand the chart.
- For a large family, make a main chart with a few generations and separate branch charts. Add matching names or reference labels to show how the pages connect.
- Keep a separate source list or research notes. The chart stays readable, while you retain the reasons behind uncertain or conflicting entries.
Troubleshooting
The names do not fit: Switch to larger paper, use a digital canvas, shorten optional notes, or divide the family into branches. Do not shrink the writing until it becomes hard to read.
You are missing information: Leave space for later additions and mark the detail “unknown” or “needs checking.” Ask relatives specific questions, such as a person’s full name or which generation they belong to, and compare answers with records when available.
Two sources disagree: Keep both possibilities in your notes and indicate that the chart is uncertain. A family tree is a record of what is currently known, not a reason to present a disputed detail as fact.
The relationship lines are confusing: Redraw the chart with one person per label and simpler connectors. Add written labels such as “adoptive parent” or “stepchild” when those distinctions matter and the people represented are comfortable with them.
You need to add a relative after finishing: Use the pencil draft or digital version to extend the relevant branch. If there is no space, create a continuation page and label the connection clearly instead of squeezing in a crowded name.
Frequently Asked Questions
Which person should go at the top of a family tree?
For an ancestry tree, the oldest generation shown is usually at the top and the starting person is lower down. For a descendant tree, place the oldest ancestor at the top and descendants beneath. State the format if it might not be obvious.
How many generations should I include?
Include as many as you can show clearly and support with information. Three or four generations are a manageable starting point, but the right number depends on the purpose and available space.
Do I have to include dates?
No. Names and clear relationships are enough for a basic tree. Dates can help distinguish people with the same name, but include only details you know or can reasonably support.
How should I show adoption or step-relations?
Use clear labels or a legend, and choose wording that respects the people and family members represented. There is no single layout that fits every family, so explain what the lines and labels mean.
Can I draw a family tree if some information is unknown?
Yes. Leave gaps, mark information as unknown, or use a question mark in your working copy. A tree can be useful without being complete.
What is the difference between a family tree and a genogram?
A family tree mainly shows family connections across generations. A genogram is a more detailed diagram that may also record patterns or information about relationships; it is often used in professional settings and needs a clear explanation of its symbols.
