Evidence and confidence

How to read the evidence

Every relationship, date and place on this site carries a label saying how well the records support it. The same words are used in the catalogue, the person dossiers, the family atlas and the study pages. The label is always written out, so no state depends on colour alone. The labels describe evidence; they are not a verdict on anyone’s family tradition.

Relationship and claim labels

These labels come from this project’s own review of the records. They run from strongest to weakest, followed by conflicts. “Documented” is used only when a cited record states the relationship or fact directly.

LabelWhat it means
DocumentedprovedA cited record states this directly, and the research has checked that the record belongs to this person.
Strongly supportedstrongly_supportedSeveral independent, consistent records point to this, but no single record states it outright.
ProbableprobableThe evidence favours this over the alternatives, but it is not proved and could still change.
PossiblepossibleConsistent with the evidence so far. A lead to test, not a conclusion.
UncertainuncertainFlagged as uncertain, either by this research or by the tree contributor. Treat as unresolved.
DisputeddisputedRecords or researchers disagree, and the conflict is not resolved.
ContradictedcontradictedThe available records argue against this link. It is shown only so that readers can see why it was rejected.
SupersededsupersededAn earlier proposal that later research has replaced. Kept for the audit trail.

Marks copied from the family tree

Many links come from WikiTree profiles. When a contributor has marked a parent link, the mark is shown with the word “Tree” so that it is not mistaken for this project’s assessment. A link with no mark is called unassessed.

LabelWhat it means
Unassessed tree linkunmarkedCopied from the family tree with no certainty mark. It has not been assessed against records.
Tree-marked confidentconfidentThe WikiTree contributor marked this link as confident. It is the contributor’s judgement, not an assessment by this project.
Tree-marked DNA confirmeddna_confirmedThe WikiTree contributor marked this link as confirmed with DNA. This project has not independently checked that DNA reasoning.
Tree-marked non-biologicalnon_biologicalThe tree marks an adoptive, step or other non-biological relationship.

Record quality

Each source is classed by how close it is to the original event. The class describes the source, not the conclusion drawn from it.

ClassWhat it means
Original recordAn image or original register, return, will or deed that has been inspected.
Index or transcriptionAn index, abstract, calendar or transcription of an original. Useful for finding the original, but open to copying errors and omissions.
Secondary sourceA published history, family account or later compilation. Its claims need their own sources.
Tree/profile onlyKnown only from a family-tree profile. A lead to look for records, not evidence in itself.
UnclassifiedThe source has not yet been classified. Do not assume it is an original.

Record associations

Catalogue record rows use these terms for the link between a person and a record.

Documented
A cited record places this person in this event.
Probable
The record probably concerns this person, but the identification is not proved.
Profile lead
Reported on a tree profile; inspect its sources before relying on it.
Kin-inferred profile lead
Placed through a relative’s tree profile, not through a record naming this person.
Traditional
A family tradition or later account without a contemporary record.
Estimated
A date or place inferred from other evidence, such as an age at death or a later census.

Estimated dates and places

A date or place without a record behind it is marked as an estimate or a limit. An estimate is a working value; it can move when a record is found.

Exact
A day, month and year taken from a record.
c. / about
An approximate date, usually calculated from an age or a nearby event.
before / after
A limit only: the event happened before or after this date.
Estimated
A date or place inferred from other evidence. It is a working value, not a recorded fact.
Place not established
No reviewed record gives the place; a tree value may be shown separately as a lead.

Research clusters are not proof of kinship

Research clusters, households and study groups organise related records and hypotheses. Being placed in the same cluster does not prove that people were related. A family atlas branch or a visual root is a layout choice, not a shared ancestor.

Study page scale

Family and locality studies use a shorter four-step scale for their clusters and links.

Documented
A cited record states the link.
Strongly supported
Consistent records support it; none states it outright.
Working hypothesis
A proposal the study is testing; not a conclusion.
Unresolved
Not yet assessed, or the records do not decide it.

Open research questions

Open questions on the research page and in person dossiers use these fields.

Open
Still being researched. The question shows what would resolve it and which record to request or inspect.
Partly answered
Part of the question is settled; the remaining part stays open.
Answered
Settled by the records named in the task. Kept so that the reasoning stays visible.
What would resolve this
The finding that would settle the question, as stated in the maintained research.
Record to request or inspect
The particular register, file or index entry to consult next.
Not yet identified
The research has not yet named a deciding finding or record. The site does not fill the gap with a guess.

If a label looks wrong

Send the profile, the exact claim and the record that bears on it through the correction form. A label changes only when the evidence does.
