How to Make a Family Tree Online: Step-by-Step for Beginners
You've been meaning to do this for years. Maybe it started when a relative asked about your grandparents, and you realized you couldn't answer. Maybe it was cleaning out the attic and finding a box of old photos with no names written on the back. Or maybe you just want to give your kids a sense of where they came from before those memories fade.
Whatever brought you here: making a family tree online is one of the most rewarding things you can do with an afternoon. And it is a lot easier than most people think.
You will use three core genealogy building blocks throughout this guide: vital records, GEDCOM portability, and family collaboration.
This guide walks you through every step - from choosing a free tool to adding your first relatives and collaborating with family members across the country.
What You'll Need Before You Start
You do not need much. Honestly, you do not need anything except a browser and fifteen minutes.
That said, having a few things handy will make the process smoother:
- Names of your parents and grandparents (full names, maiden names if you know them)
- Approximate dates - birth years are enough to start; you can add exact dates later
- A few photos - even low-quality scans of old photos add a lot of life to a tree
- Any documents you have lying around - birth certificates, immigration papers, old letters
No documents? No problem. Start with what is in your head and fill in the gaps as you go.
Step 1: Choose the Right Family Tree Builder
There are dozens of tools out there, and the differences matter. Here is what to look for in a free family tree builder:
No forced paywall after 10 people. A lot of the big genealogy platforms let you start for free, then lock you out once you are invested. Read the fine print before committing.
Browser-based. You should not need to download anything. The best tools run right in your browser and save automatically.
GEDCOM support. GEDCOM is the universal file format for genealogy data. A tool that supports it means your data is never trapped - if you ever want to switch platforms, everything comes with you.
Real collaboration. Eventually you will want a cousin to fill in their side of the family. Emailing spreadsheets back and forth is a nightmare. Look for built-in sharing and editing.
We built Lineage to check all of these boxes - completely free, browser-based, no paywalls, with GEDCOM import and collaboration features built in. Whatever tool you choose, make sure it passes the "actually free to use" test before you invest time in it.
Step 2: Start with What You Know
Here is the single most common mistake beginners make: trying to build the whole tree before they build any tree.
Start with yourself. Add your name, your birth year, where you were born. Then add your parents. Then your grandparents. Then stop.
That is three generations - somewhere between 7 and 14 people. And already you have something real. Something you can share. Something that exists.
From there, branch outward:
- Add your siblings
- Add your parents' siblings (your aunts and uncles)
- Add your grandparents' parents if you know them
Work backwards from what you are certain about. Resist the urge to guess or enter placeholder names - it gets confusing fast, and guesses tend to calcify into "facts" over time.
Step 3: Gather Information from Relatives
This is the step people skip, and it is the step they later regret most.
Your oldest living relatives are your most valuable source of information - and that information is not going to be available forever. A phone call or a holiday visit where you ask a few pointed questions can unlock more family history than weeks of archive research.
Good questions to ask:
- What were your parents' full names, including your mother's maiden name?
- Where and when were you born?
- Do you know where our family originally came from?
- What do you remember about your own grandparents?
- Are there any family stories I should know about - migrations, name changes, anything unusual?
For written records, a few strong free starting points:
- FamilySearch.org - free, massive worldwide database, the best single starting point for almost any family
- National Archives (archives.gov) - US census, military, and immigration records
- ScotlandsPeople - detailed records for Scottish ancestry going back to 1538

Step 4: Add Photos, Stories, and Context
A family tree built only from names and dates is a spreadsheet. A family tree with photos, stories, and context is a living document.
Once you have the basic structure in place, start enriching it:
- Upload photos. Old scanned photos are perfect for this. Even a blurry one from the 1960s adds genuine personality.
- Add occupations. Knowing that your great-grandfather was a blacksmith - or that your grandmother was one of the first women in her village to attend university - makes them feel real.
- Write short biographies. A few sentences about what you remember or were told about each person goes a long way.
- Record stories. The funny ones, the sad ones, the ones that explain why your family is the way it is.
None of this has to be complete. A few sentences per person across three generations adds up to something remarkable over time, and it gives future generations something alive to read - not just a chart.
Step 5: Invite Family Members to Collaborate
Here is something that surprises most people: other members of your family want to help.
Your aunt might have all the photos from the 1970s. Your cousin might have been researching the same family tree from a different angle for years. Your dad might remember details about your grandparents that you never knew.
Most family tree tools let you invite others to view or edit the tree. Use this feature. Send a link to a few relatives and tell them what you are building. You will be surprised how quickly it grows.
A few collaboration tips:
- Give view-only access to relatives you trust not to accidentally overwrite things
- Give editing access to close family members who have solid information to add
- Ask each branch of the family to fill in their own section - this distributes the work and brings in perspectives you would never have reached alone
What to Do When You Hit a Dead End
Every family tree has gaps. Names changed at border crossings. Records were destroyed in wars or fires. Relatives lost contact across generations.
When you hit a wall, try:
- Alternative spellings. Surnames were often written phonetically by immigration officials. "Kowalski" became "Cowalski." "Petrossian" became "Peterson." Search with variations.
- The country of origin's archives. If US records run dry, try Polish, Ukrainian, Armenian, or other national archives. Our records guide covers many of them.
- DNA testing. Services like AncestryDNA or 23andMe can connect you with distant cousins who may have already done research you haven't. It is not a magic solution but it can break open otherwise impossible walls.
Dead ends are not failures. They are just the beginning of a longer, more interesting search.
Start Today - Not Someday
You do not need to know your entire family history to start. You do not need to have all the documents. You do not need to be a genealogist.
You just need to start with what you know, put it somewhere permanent, and keep adding to it.
Because the alternative is waiting - and with every year, more of this becomes impossible to recover. The people who knew the stories are not going to be here forever.
