Delphia Welford
Delphia S. Welford (September 9, 1875 – November 14, 1992) was an American supercentenarian claimed to have been born on September 9, 1881; however, research conducted by the Gerontology Research Group between 2016 and 2023 concluded that she was actually born in 1875, and that she was born in Okolona, Mississippi. LongeviQuest has subsequently conducted similar research and a similar analysis and reached an identical conclusion, with Delphia Welford having four documents (two US Census entries and two Mississippi state census entries) from 1880 to support her claimed age and with additional documents (Mississippi school census entries) from 1885 and 1892 that decisively rule out the possibility of an identity switch with a younger sibling and that either support or almost support (produce a final age one or two years younger than) her claimed age.
Welford's parents were Richard and Heddie Welford.
Begin with the source’s own compact description: “List of American supercentenarians” is wikimedia list article. The dossier treats that line as a proposition to test through List, American and supercentenarians, not as a finished interpretation.
Why this record matters
The phrase “wikimedia list article” 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.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 22, 2026. The linked authority identifier is Q2309504. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2015, 1910, 1999 and 1903.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
