Keep the evidence beside the family story

Write down the source while you have it

When a relative shares a memory, note the person, the date of the conversation and the detail they described. When you inspect a record, note its title, the archive or collection and the identifier or location that would help you find it again. A source note does not need to sound academic to be useful; it needs to let another reader retrace your steps.

Separate what the source states from what you infer. A letter may mention an aunt without identifying which side of the family she belongs to. A photograph may show people together without proving their relationship. Copy the relevant detail accurately, then explain your interpretation in a separate note. This prevents a reasonable working idea from becoming an apparent quotation or documented fact.

Let conflicting details remain visible

Two sources may disagree about a name, age or place. Keep both versions until you have a reasoned basis for choosing one, and record that basis when you do. Do not silently replace a family memory just because a document looks official, or ignore a document because a familiar story feels convincing. The question is what each source actually supports in its context.

Use uncertainty labels consistently: exact, approximate, disputed or unknown are often enough for a working record. If a year is estimated from an age in a later document, explain that calculation and its limitations. Avoid turning a range into a single date for visual neatness. The chart should help communicate the research, not force the research into more certainty than it has.

A practical source entry can contain three parts: the detail being supported, where to find the material and your interpretation. For instance, describe the name as written in a family letter, identify the letter by date and keeper, then note any uncertainty about the person mentioned. If you later revise the interpretation, the source description can remain intact. This separation lets relatives contribute additional context without overwriting the original evidence, and makes it easier to explain why a previously accepted connection is now under review.

Turn a gap into a research question

Choose one unresolved detail and write a question narrow enough to answer. Instead of finding everything about a grandparent, ask which place is recorded for a particular event. List the material you already have and what additional source could help. Note searches that did not produce an answer so that you do not repeat the same work without a new reason.

Preserve copies of useful material with clear filenames and a brief description. Keep a separate record of where the original is held and any restrictions you were told about sharing it. At the end of a research session, update the tree only with the information the evidence supports. Leave the remaining question open; an honest gap is a valuable part of a reliable family history.
