A family tree outline is a structured diagram that maps the relationships between members of a family across generations, typically starting with a single ancestor or couple at the top and branching downward. The most common format is a pedigree chart, which shows direct ancestors in a compact, standardized layout, while a descendant chart (or family group sheet) expands to include siblings, spouses, and their children. Understanding the basic outline formats helps you choose the right one for your research and presentation needs.
What a Family Tree Outline Actually Shows
At its core, a family tree outline is a visual representation of genealogical data. The two primary types are the pedigree chart and the descendant chart.
- Pedigree chart (ancestor chart): This outlines only your direct line—parents, grandparents, great-grandparents, and so on. It typically starts with you (or a chosen ancestor) on the left or top, and branches into two parents, four grandparents, eight great-grandparents, etc. It is the most compact way to trace a single lineage.
- Descendant chart: This starts with a specific ancestor and shows all their descendants—children, grandchildren, great-grandchildren—often including spouses. It is wider and more detailed, useful for family reunions or documenting a full family line.
- Family group sheet: This is a text-based outline that lists one family unit: a couple, their marriage date, and each child with birth, death, and marriage details. It is not a diagram but a standard record form used by genealogists.
Most genealogy software (like Ancestry, MyHeritage, or FamilySearch) can generate these outlines automatically from your data, but understanding the structure helps you read and verify them.
How to Choose the Right Outline Format
Your choice depends on what you want to highlight. If you are tracing your direct ancestry to find immigrant origins or royal connections, a pedigree chart is best. If you are organizing a family reunion or want to show how everyone is related to a common ancestor, use a descendant chart.
Consider the number of generations you have. A five-generation pedigree chart (you, parents, grandparents, great-grandparents, great-great-grandparents) fits on a single page in a landscape orientation. A descendant chart can run to many pages if the family is large. For beginners, starting with a three-generation pedigree chart (you, parents, grandparents) is manageable and easy to fill in from memory before you begin archival research.
Also decide whether you want a horizontal or vertical layout. Vertical charts (ancestor at top, descendants below) are common in Western genealogy. Horizontal charts (ancestor on the left, descendants to the right) are often used for wide descendant trees. Both are valid; choose based on how many names you need to display.
Step-by-Step: Building Your Outline
Creating a family tree outline from scratch is straightforward if you follow a logical sequence.
- Start with yourself (or the person of interest) at the base or left edge.
- Add your parents as the next generation, then your grandparents, and so on for a pedigree chart.
- For a descendant chart, start with the oldest known ancestor and list all children, then each child’s spouse and children, continuing down.
- Use standard symbols: a square for males, a circle for females, a horizontal line connecting spouses, and a vertical line dropping to children. These are the internationally recognized genealogical symbols.
- Record dates and places for birth, marriage, and death if known. Even if you leave spaces blank, the outline shows where data is missing.
- Number generations (e.g., I, II, III) or use a numbering system like the Ahnentafel (a numbering method where the father of person n is 2n and the mother is 2n+1). This is optional but useful for large trees.
If you are using paper, a pencil is wise because corrections are common. Digital tools allow easy editing and automatic formatting.
Common Problems and How to Avoid Them
Several pitfalls trip up beginners when creating a family tree outline.
- Duplicate names: The same ancestor may appear multiple times if you have not merged records (e.g., a great-grandmother who appears in two different branches due to cousin marriage). Use unique identifiers or notes to track them.
- Incorrect relationships: Step-parents, adoptions, and remarriages complicate outlines. Clearly mark biological vs. legal relationships. For example, a half-sibling shares only one parent; your outline should show that by connecting them to the shared parent only.
- Generational gaps: If you skip a generation, the chart becomes confusing. Always maintain a continuous line from parent to child.
- Overcrowding: Too many names on one page makes it unreadable. Split large trees into sections or use a software-generated chart that can zoom.
A common misconception is that a family tree must be a perfect pyramid. In reality, families with no children or with many children will have irregular shapes. That is fine—the outline reflects reality, not symmetry.
Digital Tools vs. Hand-Drawn Outlines
You can create a family tree outline with pen and paper, a spreadsheet, or dedicated genealogy software. Each has trade-offs.
- Paper: Simple and portable, but hard to edit and limited in space. Good for a first draft or a small tree.
- Spreadsheet (Excel/Google Sheets): Useful for data organization, but not ideal for visual diagrams. You can use a template, but it lacks automatic relationship lines.
- Genealogy software: Programs like Family Tree Maker, Legacy, or online platforms like Ancestry and MyHeritage automatically generate charts from your data. They handle duplicates, sources, and multiple chart types. Most offer free basic versions.
- Online chart builders: Websites like Family Echo or Canva offer free templates where you manually add names and relationships. These are easy for beginners but do not store source citations.
For long-term research, software with source management is essential. For a one-time visual, a free online builder is sufficient.
Costs and Where to Get Free Templates
You do not need to spend money to create a family tree outline. Many free resources exist.
- FamilySearch (familysearch.org): A free genealogy website that lets you build a tree and print pedigree charts. It is run by The Church of Jesus Christ of Latter-day Saints, but the service is free to all.
- Ancestry.com: Offers a free trial, but a subscription is required for full access to records. You can build a tree for free, but printing high-quality charts may require a paid plan.
- MyHeritage: Similar to Ancestry; free tree building, but advanced features like chart printing are paid.
- Printable templates: Many genealogy blogs and sites offer free PDF templates for five-generation pedigree charts and family group sheets. Search for “free printable family tree template.”
If you use a professional genealogist, they may provide charts as part of their service, but that is a separate cost. For most hobbyists, free tools are sufficient.
Accuracy and Source Citation
An outline is only as good as the data behind it. Always cite sources for each fact—birth certificates, census records, family Bibles, or oral interviews. In genealogy, a common standard is to list the source in a footnote or a separate source field. Without sources, your tree may contain errors that propagate.
Be especially careful with names that are spelled differently in different records (e.g., “Schmidt” vs. “Smith”). Use the spelling from the earliest record and note variations. Also, verify dates: a birth year on a tombstone may differ from a baptism record. When you have conflicting data, include both and note the discrepancy.
For living people, privacy is a concern. Many online platforms restrict access to living individuals. If you share your tree publicly, ensure that living relatives are marked as private.
Frequently Asked Questions
What is the difference between a pedigree chart and a family tree?
A pedigree chart shows only your direct ancestors (parents, grandparents, etc.) in a compact format. A family tree is a broader term that can include a descendant chart, which shows all descendants of a common ancestor, including siblings and their families. In casual usage, “family tree” often refers to any genealogical diagram, but in genealogy, the two terms are distinct.
How many generations can a family tree outline show?
There is no limit, but practical constraints apply. A standard printed pedigree chart usually fits five generations on one page. Digital charts can show hundreds of generations, but the data becomes less reliable the further back you go. Most people can trace 10–12 generations with solid records; beyond that, documentation becomes sparse.
Can I include step-family and adopted members in a family tree outline?
Yes, but you should clearly mark the relationship. Use dotted lines for adoption or step-relationships, or add a note. For example, if a stepfather raised you, you can include him as a parent with a dotted line and note “stepfather.” Many genealogy programs allow you to define multiple parent types (biological, adoptive, foster, step).
What is the Ahnentafel numbering system?
Ahnentafel is a German word meaning “ancestor table.” It is a numbering system where the subject is number 1, their father is 2, mother is 3, paternal grandfather is 4, paternal grandmother is 5, maternal grandfather is 6, and so on. The rule is: the father of person n is 2n, and the mother is 2n+1. This allows you to reference any ancestor without a diagram, and it is useful for large databases.
Is it okay to have blank spaces in my family tree outline?
Absolutely. Blank spaces indicate missing information and guide your research. Many genealogists leave blanks rather than guessing, because an incorrect name or date can send you down the wrong path. Fill in what you know from reliable sources, and leave the rest for future research.
How do I share my family tree outline with relatives?
You can export a PDF or image from most software programs and email it, or print a large poster. Online platforms allow you to share a view-only link. For a family reunion, a printed descendant chart is a popular centerpiece. If you have a large tree, consider creating a simplified version for display, with a more detailed version available digitally.
