How to Write a Biography of Someone Who Has Died

To write a biography of someone who has died: interview everyone who knew them before doing anything else, gather documents and photographs to build a verified timeline, reconcile conflicting accounts by recording both rather than choosing, and write the gaps honestly instead of filling them with invention. The story is recoverable. It just gets assembled from many people instead of one.

Families often assume the chance is gone. It isn't — some of the most affecting life stories we've worked on were written about someone who died years earlier. What changes is the method.

Interview the living first, and quickly

This is urgent in a way the rest of the project isn't. Every person who knew them is a source that expires.

Cast the net wider than you think you need to:

• Siblings and cousins — they hold the childhood you never saw.
• Their friends, especially the ones from before the family existed.
• Colleagues — people are often unrecognisably different at work.
• Neighbours and community members — frequently the source of the small daily detail nobody in the family noticed.
• The in-laws — a son-in-law who observed for thirty years without being inside the family dynamic is an unusually clear-eyed witness.

Ask each of them the same core questions, plus one that only they can answer. And record it — our guide to recording a family member's voice applies here exactly.

Build a documented timeline before you write

You are going to receive dozens of stories with no dates attached. A timeline is what turns them into a life.

Gather certificates, passports, immigration and naturalisation papers, military records, employment documents, school reports, letters with postmarks, and the backs of photographs. Each fixed date you establish acts as an anchor that other memories can be hung from — that must have been after the move, because the baby's in the picture.

Where the family's own papers are thin, formal records fill in more than people expect. Our beginner's guide to family tree research covers which records to pursue and in what order.

When accounts conflict — and they will

Two siblings will give you two irreconcilable versions of the same childhood. This is normal, not a failure of the research.

Do not adjudicate. A biography that says my aunt remembers the house as cramped and unhappy; my father remembers it as the best years of his life is more truthful than either version, and it tells the reader something real about both of them. Where a factual detail matters — a date, a place — prefer the source created closest to the event.

The one thing to avoid is silently averaging the accounts into a bland middle version that nobody actually remembers.

Writing the gaps honestly

There will be things nobody knows: what he thought during the crossing, why she never spoke about her first marriage, what happened in those two missing years.

The temptation is to write a plausible bridge. Don't. Invented interiority is the fastest way to make a family biography untrustworthy, and later generations cannot tell which parts were reconstructed.

Instead, name the gap. We don't know what she did between 1951 and 1953; she never spoke about it, and the papers don't say. An acknowledged silence is itself part of the portrait, and it's often the most memorable page in the book.

Where you do infer, mark it plainly — it seems likely that, the family always assumed — so the reader can weigh it.

Whose voice to write it in

A memoir is first person; a biography written after death cannot honestly be. You have two workable choices.

Third person — the conventional biography. Clean, allows multiple viewpoints, handles uncertainty gracefully.

First person plural, from the family — we never knew why he kept the letter. This suits books meant for relatives, because it's honest about who is telling the story and why. It also lets the searching itself become part of the narrative.

What doesn't work is first person as the deceased. Putting words in a dead parent's mouth reads as ventriloquism, however lovingly meant. Our guide to memoir vs autobiography vs biography covers the distinctions in more detail.

Frequently asked questions

Can you still write someone's life story after they have died?

Yes. The story is reconstructed from the people who knew them — siblings, cousins, friends, colleagues and neighbours — combined with documents, letters and photographs. The result is a biography rather than a memoir, told about the person instead of by them. Families who assume they have missed the chance are usually surprised how much is recoverable, particularly when several relatives are interviewed rather than one.

Who should be interviewed for a posthumous biography?

Interview as widely as you can reach, and prioritise by age. Siblings and cousins hold the childhood, friends from before the marriage hold the years the family never saw, colleagues saw a different person entirely, and in-laws often give the clearest outside view. Neighbours and community members frequently supply the everyday detail relatives stopped noticing decades ago.

How do you handle conflicting family memories?

Record both accounts rather than choosing between them, and attribute each to the person who gave it. Contradiction is normal and often revealing, since how two siblings remember the same house says something true about both. Where a hard fact is in dispute, favour the document or the source created nearest the event, and say plainly in the text where uncertainty remains.

What if there are no documents left at all?

Testimony alone is enough to produce a meaningful book, and many families in this position end up with something more personal rather than less. Where archives were destroyed by war or displacement, look sideways to relatives who emigrated elsewhere, since another country's immigration and naturalisation records may preserve names and places lost at the origin. Community registers, restitution claims and survivor testimony collections are also worth pursuing.

Having it done for you

Reconstructing a life after death means running many interviews across scattered relatives, holding contradictory accounts without resolving them prematurely, and writing with restraint where the evidence runs out. It is a substantial piece of work, and it is emotionally heavy to do about your own parent.

It's also something we do regularly: we interview the living relatives and friends who can recount the story, gather what documents survive, and weave it all into one coherent narrative and a printed book for the family. If that's what you're facing, book a free consultation — there's no obligation, and no deadline.
