> **The short answer**
> Organize genealogy around one research question at a time. Keep one master tree, a research log and stable IDs for every source. Link each fact to evidence, record unsuccessful searches, use predictable filenames and verify your backups.

Genealogy becomes difficult to manage when three different things are mixed together: what you believe about the family, the evidence you collected, and the work you still need to do. A large tree does not solve that problem. More folders do not solve it either.

A dependable system keeps five layers connected:

1. a focused research question;
2. a log of what you searched;
3. source files that can be found again;
4. conclusions linked to evidence;
5. a short next-action list.

This guide is the map for that system. The linked guides explain each part in detail.

## 1. Begin with one question, not one surname

“Research the Carters” has no finish line. A useful question names one person, relationship, event, place and approximate period:

> Who were the parents of Ellen Carter, who married Thomas Reed in Franklin County, Ohio, around 1888?

That question tells you which identity must be distinguished, what event anchors the search and what evidence might answer it. It also prevents unrelated discoveries from taking over the session.

Create one project note for the question. Include:

- the exact question;
- known facts and their sources;
- assumptions that have not been proved;
- likely record groups;
- repositories or databases to search;
- conflicts that need explanation;
- the next smallest action.

## 2. Choose one master record of conclusions

Your master tree may live in genealogy software, an online tree or a carefully maintained set of forms. It should be the place where your current conclusions are visible—not the only place where source images and research notes exist.

For each important claim, record:

- the person it concerns;
- the event or relationship;
- the date and place as precisely as evidence permits;
- the source or sources supporting it;
- uncertainty, alternatives or conflict;
- the date you last reviewed the conclusion.

Do not maintain several trees as if each were equally current. If you use an online tree for collaboration and desktop software for control, document which one is authoritative and how changes move between them.

## 3. Use a research log during every search session

A research log answers four questions: what were you trying to learn, where did you look, what exactly did you search, and what did you find?

Record a search even when it produced nothing. A negative result can show that:

- a collection did not cover the needed year;
- a surname spelling was too narrow;
- the person was absent from a specific index;
- an image set was browsed beyond the indexed entries;
- the same search does not need to be repeated next month.

Keep the log close to the work. A perfect template opened only after the session is less useful than a simple row completed while the source is still on screen.

## 4. Give every saved source a stable identifier

A source identifier connects the image, citation, transcript, research log and conclusion. It should not depend on a filename supplied by a website.

One workable pattern is:

`SRC-2026-0042`

The catalogue row for that ID can record:

- source type and title;
- creator or issuing body;
- jurisdiction and date;
- person or household represented;
- repository or website;
- collection, volume, page, image or certificate number;
- access date and URL where appropriate;
- local filename;
- claims supported;
- notes about legibility or completeness.

If you later correct a person’s identity, the source number stays the same. Stability is more useful than encoding every conclusion in the filename.

## 5. Separate original evidence from working copies

Keep the file you downloaded or scanned unchanged. If you crop, enhance, annotate, translate or combine it, save the result as a derivative.

For example:

```text
SRC-2026-0042_census_original.jpg
SRC-2026-0042_census_detail-ellen.jpg
SRC-2026-0042_census_transcript-reviewed.txt
```

Do not overwrite an original image with a sharpened version. Do not remove the surrounding page simply because one household is the current focus; neighboring entries, headings and page numbers can matter later.

For physical documents and photographs, preserve provenance before rearranging them. Record who held the item, how it reached you, any original envelope or grouping, and where the physical item is now stored.

## 6. Build a digital folder system that can survive growth

Use a shallow structure. Deep trees of surname, generation, country, source type and event become hard to navigate because one source may belong in several places.

A practical starting structure is:

```text
Family-History/
  00_Admin-and-index/
  01_People-and-families/
  02_Sources/
  03_Research-projects/
  04_Photos-and-audio/
  05_Exports-and-sharing/
```

Keep one authoritative source file and link to it from the relevant project or person note. Avoid duplicating the same census image into four relatives’ folders; duplicates drift apart and waste storage.

The Library of Congress advises organizing digital materials, giving files descriptive names and storing backup copies separately. The National Archives also warns that digitized copies can be lost, so the originals should be retained where possible.

## 7. Use a physical binder as a workspace, not the entire archive

A binder is excellent for current pedigree charts, research plans, logs, maps and copies you want beside you. It is not ideal as the sole home for every original certificate, fragile letter or hundreds of printouts.

Use sections based on how you work:

- master index and current goals;
- pedigree and family group sheets;
- one active research project per divider;
- research logs and timelines;
- source copies needed for current analysis;
- unresolved questions and next actions.

Write the digital source identifier on every printed copy. When the project closes, remove unnecessary duplicates and update the master index.

## 8. Keep facts, hypotheses and family memory distinct

Your notes should show the status of every statement:

**Documented fact:** supported directly or indirectly by cited evidence.

**Reported memory:** attributed to a named person and interview date.

**Working hypothesis:** an explanation you are testing.

**Unresolved conflict:** evidence disagrees or identities remain uncertain.

Avoid phrases such as “probably correct” without explaining why. Write a short reasoning note: which sources agree, which conflict, how close each informant was to the event, and what would change the conclusion.

## 9. Connect people through timelines

A source-by-source folder can hide chronology. Build a timeline for a difficult person or family and attach each event to a source ID.

Include:

- event date or range;
- place at the historical level shown by the source;
- people involved;
- source ID;
- certainty;
- conflicts or gaps;
- next research question.

Timelines reveal impossible overlaps, children born in different jurisdictions, long gaps between records and two people with similar names.

## 10. Protect living people and sensitive records

Separate material about living people from the shareable family archive. Do not publish dates, addresses, identifying documents, DNA information or private interviews merely because the software permits it.

Record access restrictions alongside the file rather than relying on memory. Before sharing a folder or export, open it as the recipient would and verify that private notes, hidden media and unrelated living-person details are absent.

For legal restrictions on specific record collections, privacy rights or archival deposits, consult the applicable repository and jurisdiction. An organization system does not grant permission to publish.

## 11. Back up the archive and test recovery

A copy on the same computer is not enough. Keep:

- the working archive;
- a local backup on separate media;
- another trusted copy in a different location.

Cloud synchronization can be useful but may also synchronize deletion. Confirm that version history or recovery exists. Keep an export of your master tree in a broadly supported format such as GEDCOM where appropriate, alongside application-specific backups and a note naming the software/version that created them.

Test twice a year:

1. restore a small folder to a temporary location;
2. open several source images and documents;
3. confirm the tree backup can be read;
4. compare file counts or checksums for important collections;
5. record the test date and result.

## 12. Use a weekly closing routine

At the end of a session:

1. finish the current research-log row;
2. download and name the source;
3. add or correct the citation;
4. connect the source to claims;
5. state what remains uncertain;
6. write the next action;
7. allow the backup to complete.

Once a week, clear the download folder and paper intake tray. Do not begin a new branch until the evidence from the previous session has entered the system.

## The smallest system that works

If your current archive is overwhelming, begin with only five things:

- one research question;
- one research log;
- one folder for newly saved sources;
- one index with stable source IDs;
- one verified backup.

You can add binders, timelines and specialized forms after this loop works. Organization should reduce repeated decisions, not create a second hobby beside genealogy.

## Start with free genealogy tools

The free [Genealogy Starter Tools](/free/genealogy-starter-sheets) include a pedigree chart, research log and source sheet in A4 and US Letter. For a larger printable working system, see [The Ancestor File](/shop/the-ancestor-file) or [The Family History Binder](/shop/family-history-binder).

## Choose a connected research system

If you want a coordinated set of research pages rather than individual sheets, compare [The Complete Genealogy Library](/shop/complete-genealogy-library). Check its contents against the records you already keep before choosing a bundle.

## Turn one finished piece of research into a family gift

A holiday deadline is a reason to choose a small, supported project rather than rush an uncertain family connection into a finished tree. A captioned photograph, a recipe with its source or a documented branch can be complete on its own. The [family history Christmas gift guide](/family-history-christmas-gifts) explains how to prepare a readable recipient copy while keeping your research notes and uncertainties.
