Editorial reviewStrongest as a route into the people, institutions and dated events that shaped the subject’s public record. The current lead gives the account dated anchors—1822, 1907, 1871, 1874—that can be checked directly. The linked authority record independently contributes the date 1822-01-01.

Evidence profile

Chronology provides the most reliable spine for this subject; interpretation should follow only after identities and dates are secure. The source revision retrieved here is dated Jul 23, 2026. The linked authority identifier is Q50960854. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1822, 1907, 1871 and 1874.

Critical limits

Public reputation and documentary evidence do not always develop together; absence from a summary is not evidence of historical absence. 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.
