Start with a question you can answer
A timeline is not finished merely because its years look orderly. It should help answer a question: when did your mother leave the village, during which years did your grandfather teach, or when did a household begin living in two places? Define the person, period, and events before putting an entire family into one table. The National Archives’ getting-started toolkit encourages organizing material and proceeding in stages.[1] Here that principle becomes a worksheet with a limited scope. Put the question at the top and leave a space for material currently outside it. An interesting distant relative need not be forgotten or allowed to interrupt the question immediately. A small, checkable timeline helps relatives more than a huge unsupported chronology.
Keep two dates for each event
Use at least two fields: event date and date the material was created. A birth may have occurred in one year but been described in a memoir decades later; a registration form may recall an earlier move. Copying the document date into the event field creates false precision. Add person, event, place, exact wording, source identifier, and assessment status. Enter the wording before summarizing, so “moved here last winter” does not silently become “moved in January.” Without a month, record only a year; without a certain year, use a range. If software requires complete dates, preserve the original expression in a separate text column instead of inventing January 1. Convenient sorting must serve evidence rather than alter it.
Give date ranges a real basis
A range explains known boundaries rather than hiding ignorance. In a fictional example, a March letter still uses an old address while a September letter uses a new one. You can say the correspondence address changed between March and September, but not that the person moved in May or that the whole household moved together. A delivery address might also be somewhere collecting mail on their behalf. Note the limitation and seek a lease, school record, neighbour’s recollection, or other evidence of residence. Retain a one-sided boundary if all you can say is “not before” or “not after.” Do not turn a range’s midpoint into a birthday or moving date: it is a convenient calculation, not a historical event. The more precise a range, the clearer its derivation must be.
Handle calendars and ages separately
When dates use a lunar calendar, reign year, traditional age reckoning, or vague age, do not silently convert them on first entry. Preserve the wording and separately record any conversion, tool or basis, and uncertainty. If someone says they entered the city at eighteen, you still need to know how they counted age, how reliable the recollection is, and whether their birth year is disputed. Conversion addresses a calendar or arithmetic problem; it does not verify memory. You might write “approximately eighteen according to oral account; year unverified.” Discuss midnight, time zones, or regional differences only when they affect the present question. For a beginner, preserving an incomplete date faithfully usually matters more than calculating a handsome complete one without support.
Show conflicts side by side
When two items disagree, create two rows instead of overwriting one with the more appealing version. In a fictional example, an interview dates the start of an apprenticeship to 1952, while the name first appears in a wage book in 1953. They may conflict, or describe different stages such as a trial period before paid work. Those are explanations to test, not facts to insert for narrative smoothness. Compare the writer, distance from the event, purpose of recording, and firsthand knowledge. A census can supply household and place clues, but it records a particular moment and requires reading that year’s fields and instructions.[2] One record cannot guarantee an entire life story. Plan further work on the most consequential conflict and retain the rest.
Separate context from personal experience
A separate context column can record transport openings, school foundations, or administrative changes, clearly labelled as background rather than personal events. A railway opening does not prove that your grandfather travelled on it; a local disaster does not establish that relatives left because of it. Letters, records, or explicit recollections are still needed to connect context to personal experience. Explain what was happening locally to help readers understand the setting, then state whether surviving material indicates an effect on this person. Context should guide checking, such as testing whether a route was feasible, rather than assign feelings, motives, or choices to someone whose voice is missing. An ordinary life need not connect to every major event to deserve recording.
Choose one next step from the gaps
A gap is not a failure. Circle the interval between two established records and ask which unknown matters most to the question. For a move, prioritize addresses; for employment, employers or wages; for caregiving, co-residents and correspondence. Write one executable action, such as checking a school’s admission register for two named years, instead of “find more information.” Check whether the material survives, is accessible, and has a relevant index. Record the scope of an unsuccessful search so you do not repeat it. If no register survives for a year, that absence cannot mean the person did not attend. Showing the boundaries of the evidence directs effort toward work that can actually advance.
Publish an honest version
Before sharing with relatives, retain labels such as approximately, according to recollection, and possibly, and attach a clickable or traceable source number. Do not replace ranges with single years or hide disputes in invisible notes for visual tidiness. A pale colour can indicate inference, but add words so colour is not the only signal. State the compilation date and unresolved questions at the bottom, and record which judgments change in updates. A narrative can begin with a clear small scene and return to the timeline to show its position. Before Us cares about how a life unfolded: when someone gained a room, parted from family, or resumed correspondence. A timeline connects those fragments while allowing us to say honestly what remains unknown.
