Family archives
Build a family timeline from source records
Put each event in order with its date, its source and your confidence in it. When two records disagree, keep both entries. A timeline that shows the conflict is more useful than a tidy sequence that hides it.
Person or family: [ ] Timeline version and date: [ ] Event: [ ] Date as recorded: [ ] Source and where it is kept: [ ] Type of record: [ ] Confidence and the reason for it: [ ] Conflicting record: [ ] Conflicting date: [ ] Source of the conflict: [ ] What might settle it: [ ] Who or where to ask: [ ] Status, open or settled, and the source document that settled it: [ ]
Conflicts that get smoothed away
Keep conflicting dates visible and explain the evidence behind each one. Note who supplied information, when it was produced and how directly it relates to the event; a document type alone does not determine reliability. If a claim came from another family tree, record that provenance and look for its underlying evidence. An uncited tree leaves a question to investigate. Label estimates derived from other events, and avoid selecting a date simply because it makes the sequence look tidy.
Check that each event date has a traceable source and that conflicting dates remain visible. Flag confidence ratings based only on plausibility or document type. Ask who supplied the information, when and on what basis. Preserve another tree as the source of a claim while identifying missing underlying evidence.
Chase the conflicts
Investigate conflicts using the sources already available and any additional material you can find. Record what changed your assessment, including a corrected reading of an existing document. Keep prior interpretations in the notes so relatives can follow the reasoning. Update confidence with a dated explanation, then share the timeline as a working draft with unresolved questions visible.
