How to Make a Family Tree: A Complete Step-by-Step Guide

Building a family tree is one of the most rewarding projects you can take on: it turns scattered names and half-remembered stories into a single, clear picture of where you come from. This guide walks through the whole process — from the first name you write down to a finished chart you can print and share.

Start with yourself and work backwards

Every family tree starts with a single person, and the easiest person to start with is you. Add your own details first, then your parents, then their parents. Working backwards one generation at a time keeps the tree accurate and stops you from guessing at connections you cannot yet prove.

For each person, try to record:

• Full name (including maiden names, which are essential for tracing women's lines)
• Dates of birth, marriage, and death
• Places they lived
• Relationships — parents, spouses, and children

You will not have all of this at the start. That is normal. Add what you know and leave the rest to fill in later.

Gather information from the people around you

Before you touch any online record, talk to your living relatives. Older family members are the single best source you have, and that source does not last forever. Ask open questions: where the family came from, what people did for work, who married whom, and whether anyone kept documents, photos, or a family Bible.

Write down (or record) everything, even details that seem irrelevant. A nickname or an old address can be the clue that unlocks a whole branch later.

Verify with records

Once you have a rough shape, confirm it against real records: birth, marriage, and death certificates; census returns; immigration and military records. Free resources like FamilySearch hold billions of records, and national archives often publish census data online. If you already have research in a paid tool, you can usually export it and continue for free — see our guide on free alternatives to Ancestry.

Record where each fact came from. Sourcing feels tedious, but it is what separates a family tree you trust from a list of guesses.

Choose how to organize it

Not every family is a neat pyramid. Second marriages, step-parents, and half-siblings are the rule, not the exception, and a good tree should show them accurately rather than forcing everyone into tidy pairs. If your family has remarriages or blended households, read how to chart a blended family tree.

It also helps to decide what kind of chart you want before you get too far — an ancestor chart, a descendant chart, or something in between. Our guide to types of family tree charts explains the trade-offs.

Use a tool that grows with you

You can start a family tree on paper, but it quickly outgrows the page. A digital builder lets you add people without redrawing everything, rearranges the layout automatically, and keeps the whole tree in one place. Blaadline is a free, browser-based builder that does exactly this: add parents, spouses, and children with a click, connect existing people instead of duplicating them, and watch the chart lay itself out as it grows.

If you already have a family history file, you do not have to start over. Blaadline imports GEDCOM files, the universal genealogy format, so you can pick up where you left off.

Finish with something you can hold

A family tree is meant to be shared. Once yours is in good shape, turn it into a printable chart — sized for a single page, or as a poster for framing. A printed tree is what gets passed around at family gatherings and handed down to the next generation.

The short version

1. Start with yourself and work backwards, one generation at a time.
2. Interview living relatives before anything else.
3. Verify each connection against real records, and note your sources.
4. Pick a chart style that fits your family's real shape.
5. Build it in a tool that lays out and saves the tree for you.
6. Print it and share it.
