Family tree forms are structured templates used to record and display genealogical relationships, typically showing ancestors, descendants, or both in a visual format. These forms range from simple pedigree charts for direct lineage to detailed family group sheets that capture vital information about each individual.
What Are Family Tree Forms?
Family tree forms are pre-designed documents that help genealogists and hobbyists organize family history data. They standardize how information is recorded, making it easier to compare, share, and analyze. Most forms include fields for names, dates, and places of birth, marriage, and death, along with spaces for notes and sources.
The two most common types are the pedigree chart (also called an ancestor chart) and the family group sheet. A pedigree chart shows a single person’s direct line of ancestors—parents, grandparents, great-grandparents—in a branching tree format. A family group sheet focuses on one nuclear family: a couple and their children, with full vital data for each person.
Historical Background
Formalized family tree forms became popular in the 19th century, when genealogy emerged as a popular hobby among middle-class families. Early forms were often hand-drawn or printed on paper, with elaborate borders and spaces for handwritten entries. The Church of Jesus Christ of Latter-day Saints (LDS Church) played a major role in standardizing these forms, as its members used them to gather genealogical data for religious purposes. In the 20th century, forms were mass-produced by genealogy supply companies, and today they are widely available as free PDFs and digital templates.
How to Use a Family Tree Form
Using a family tree form is straightforward, but there are best practices to keep your records accurate and useful.
- Start with yourself or a known ancestor—write your name (or the root person’s name) in the first box.
- Work backward for pedigree charts: parents in the next row, grandparents in the row after, and so on. Use one box per person.
- Use full names as they were at birth, and add maiden names for married women.
- Write dates in a consistent format (e.g., 12 Mar 1856) to avoid confusion between American and European date orders.
- Include locations with as much detail as possible—town, county, state, and country.
- Cite sources on the form or in a separate notebook, such as census records, birth certificates, or family Bibles.
For family group sheets, list the husband, wife, and each child in birth order. Add marriage date and place, and note any adoptions or step-relationships clearly.
Choosing the Right Form
Your choice of form depends on your research goal and the level of detail you need.
- Pedigree chart—best for a quick overview of direct ancestors. It shows lineage at a glance but omits siblings and spouses of ancestors.
- Family group sheet—essential for documenting complete families, including all children and their spouses. This is the backbone of most genealogical research.
- Descendant chart—starts with an ancestor and shows all descendants, useful for family reunions or surname studies.
- Fan chart—a decorative circular form that displays multiple generations around a central person, popular for framing or gifts.
- Blank forms—versatile for handwritten use or for scanning into digital files.

Common Problems and Pitfalls
Even with a good form, mistakes happen. The most frequent issues include:
- Duplicate entries—the same person appears twice because of name variations or remarriage. Always cross-check.
- Incorrect dates—transcribing a 1 as a 7 or mixing up day and month. Double-check against original records.
- Missing places—writing only “England” instead of the parish and county, making it hard to locate records.
- Assuming surnames change—women’s maiden names are often lost if you only use married names.
- Overcrowding—trying to fit too many generations on one page; use multiple sheets and reference them.
A common misconception is that a family tree form is a legal document. It is not—it is a research aid. Always verify information with primary sources before publishing your tree.
Digital vs. Paper Forms
Both formats have advantages. Paper forms are portable, do not require a device, and can be filled in during interviews with elderly relatives. They also serve as archival keepsakes. Digital forms, such as those in genealogy software or online databases like Ancestry and FamilySearch, allow automatic linking, source attachment, and easy sharing. Many researchers use a hybrid approach: paper for initial interviews, digital for storage and analysis.
If you use digital forms, consider exporting your data to GEDCOM—a standard file format that lets you move your tree between different software programs. This prevents vendor lock-in and preserves your work.
Costs and Where to Find Free Forms
Most family tree forms are free. Many genealogy websites, including FamilySearch (free with registration), offer printable PDFs. Local libraries and genealogical societies also provide free paper forms. Paid genealogy software (e.g., Ancestry, Legacy Family Tree) includes forms as part of their subscription or one-time purchase, but you do not need to pay for basic forms. If you buy a printed form, expect to pay a few dollars for a pad of 50 sheets.
Frequently Asked Questions
What is the difference between a pedigree chart and a family group sheet?
A pedigree chart shows only direct ancestors (parents, grandparents, etc.) in a branching line, typically covering 4–5 generations. A family group sheet focuses on one couple and their children, listing full names, dates, places, and sources for each person. You need both for thorough research: the pedigree chart gives you the big picture, while the family group sheet provides the details.
Can I use a family tree form for adoption or step-families?
Yes, but be clear about relationships. Many forms have a “notes” section where you can explain adoptions or step-relationships. Some genealogists use a dashed line to indicate adoption or non-biological parentage. Always record the biological parents if known, and note the adoptive parents separately. This keeps the tree accurate and respectful.
How many generations should I go back on a form?
Standard pedigree charts usually have space for 4 to 5 generations, but you can use multiple charts to go further back. Start with what you know and add generations as you find records. It is better to have a well-documented 3-generation chart than a speculative 10-generation one.
Are there specific forms for DNA matches?
No, DNA testing companies provide their own charts and tools for visualizing matches, but those are not traditional family tree forms. You can use a regular pedigree chart to map your known ancestors and then compare your DNA matches against that chart. Some genealogists create “cousin charts” to show how matches might be related, but these are informal.
What should I do if I find conflicting information?
Record both versions on your form, noting the source for each. Do not erase or overwrite—use the notes section. Later, you can evaluate which source is more reliable (e.g., a birth certificate vs. a census record). This practice prevents loss of data and helps you resolve conflicts systematically.
