Why this record matters
The phrase “australian female tennis player (1947-1977)” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Biographical claims are most persuasive when dates, appointments and relationships can be traced to records created close to the events described. The source revision retrieved here is dated Jan 31, 2026. The linked authority identifier is Q299601. 2 of 2 selected statements include explicit references; 1 carry qualifiers and 1 use preferred rank. The first chronological checks are 1946, 1977, 1970 and 1966.
Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
