How to Start Researching Your Family Tree (and What Genealogy Can't Capture)

To start researching your family tree, begin with what you already know, write down names, dates, and places for yourself and your closest relatives, then work backward one generation at a time using free sites like FamilySearch, subscription sites like Ancestry, and records from the National Archives. But remember the one thing records can’t give you: the living stories, which only your relatives can tell. Here’s how to do both.
Millions of people catch the genealogy bug every year, and it’s a wonderful thing. There’s real magic in finding a great-great-grandmother’s name on an old census. But there’s a trap in it too, and I want to help you avoid it.
Let me show you how to start, and how to get the part that actually matters most.
How to start your family tree, step by step
Start with yourself and work backward. Write down what you know: your details, your parents’, your grandparents’. Names, birth dates, marriage dates, places. You are the trunk; build outward from what’s certain.
Interview your living relatives first. Before you touch a database, talk to your oldest family members. They hold names, dates, and leads no record has. This is the single most important early step, and the most time-sensitive.
Gather home sources. Dig up birth and marriage certificates, family Bibles, old letters, photos with names on the back, and military papers. Your own house is a starting archive.
Use the big genealogy tools.
- FamilySearch.org is completely free and enormous, run as a public service.
- Ancestry.com is subscription-based but has vast records and hints.
- The National Archives (archives.gov) holds federal records, including the U.S. census. The most recent one available is the 1950 census.
Go one generation at a time. Confirm each person with a real record before jumping back further. It’s slow, but it keeps your tree accurate instead of hopeful.
Cite where you found things. Note the source for every fact. Future you, and your family, will be grateful.
The best places to look
| Source | Cost | Good for |
|---|---|---|
| FamilySearch | Free | Broad records, huge shared tree |
| Ancestry | Subscription | Records, hints, DNA matching |
| National Archives | Free | Census, immigration, military records |
| Your relatives | Free | Names, leads, and the actual stories |
| Local libraries & historical societies | Usually free | Local records, obituaries, newspapers |
What genealogy can’t capture
Here’s the part I most want you to hear.
A family tree gives you the skeleton: names, dates, branches. What it can never give you is the flesh. It won’t tell you what your grandmother’s laugh sounded like, why your great-grandfather really left the old country, what your family survived, or how it felt to live through the years those dates mark.
Those things don’t live in any archive. They live in the memories of the people still here to tell them, and unlike census records, those memories don’t wait 72 years to be released. They disappear the moment the person does.
So do both. Build the tree, absolutely. But while you’re at it, sit down with the living branches and record their stories, because that’s the half of your family history that’s actually running out of time. The dates will still be in the archive next year. Your grandmother might not be.
From tree to story
Once you’ve gathered both, the records and the stories, many families want to bring them together into something to keep: a family history book that pairs the documented tree with the living memories in one place. That’s the natural next step, and it’s what I help families do. Our guide on how to make a family history book walks through it.
Frequently asked questions
How do I start researching my family tree for free? Start with what you know and interview your oldest relatives, then use free resources like FamilySearch.org and the National Archives, plus your local library. Work backward one generation at a time, confirming each person with a record before moving further back.
What’s the difference between FamilySearch and Ancestry? FamilySearch.org is completely free and run as a public service with a large shared family tree. Ancestry.com is subscription-based, with extensive records, automated hints, and DNA testing. Many researchers use both, starting with the free option.
What can’t a family tree tell you? A family tree gives you names, dates, and relationships, but not the stories: why people made the choices they did, what they survived, how they felt, or what their voices sounded like. Those living memories exist only in your relatives and must be captured directly from them.
Should I do genealogy or record family stories first? Record the living stories first, or at least alongside your research. Documents and census records will still be available years from now, but your relatives’ memories disappear when they do. Interviewing your oldest family members is the most time-sensitive part of family history.
I’m Claire, a writer and personal historian on Florida’s Space Coast. I love genealogy, and I want you to remember its limit: records hold the dates, but only your relatives hold the stories. If you’d like help capturing those living stories before they’re lost, see how legacy books work or reach out. New to interviewing family? Start with our guide to questions to ask your grandparents.
