How to Build a Family Tree

Every family tree starts the same way: with you. Write down your full name, birth date, and birthplace, then do the same for your parents. That's your trunk. Everything else — grandparents, great-grandparents, siblings, cousins — branches out from there. Trying to start further back, with a famous ancestor or an old family legend, is how most people get stuck before they've made any real progress.

Start with living memory

The most reliable source in genealogy isn't a database. It's your oldest living relatives. Call your parents, grandparents, aunts, and uncles before you touch a single record. Ask for full names (including maiden names), approximate birth and death dates, hometowns, and the names of siblings. Write down the stories too, even the ones that sound exaggerated. A story about "the family that came over on a boat during a war" almost always points to a real migration you can later confirm with a passenger list or a naturalization record.

Work one generation at a time

Resist the urge to jump straight to 1700s Europe. Confirm each generation before moving to the next: name, birth, marriage, death, and location. If a generation has gaps, mark them and move on rather than guessing. A tree with honest gaps is more useful than one filled in with assumptions, because assumptions tend to get copied by other researchers and calcify into "facts" that are actually wrong.

Use records to confirm, not to guess

Once you've got names and rough dates from relatives, records fill in the rest: census records, birth and death certificates, marriage licenses, obituaries, church registers, and military service files. Each record you find should either confirm something a relative told you or raise a specific question you can go back and ask about. Treat every record as a data point, not a conclusion. Two matching sources are worth more than one confident guess.

Organize as you go

A shoebox of printouts and a dozen browser tabs will not survive contact with a real family tree. Every person needs a consistent record: name, dates, places, sources, and relationships to the people around them. This is where a proper family tree tool earns its keep. Instead of retyping the same names into a dozen spreadsheets, you add each person once and the relationships, generations, and charts build themselves.

Building a family tree is not a weekend project. It's closer to gardening: a little attention over a long time produces something worth having. Start with your trunk, add one honest branch at a time, and let the tree tell you where to look next.
