Unverified Leads (Highest Priority)
These items are not yet confirmed and must be verified against scans before citation.
- UDN 28956085 — 1932-02-14 Salt Lake Tribune, page 19.
- UDN 25941776 — 1942-05-01 Ogden Standard-Examiner, page 9.
- UDN 25602932 — 1942-05-27 Deseret News, page 15.
- UDN 17033832 — 1942-05-27 Salt Lake Telegram, page 24.
- UDN 28911552 — 1944-12-11 Salt Lake Tribune, page 9.
Unverified Corpus (Bulk)
- UDN corpus: 286 pages, spanning 1920–1955, from targeted keyword sweeps.
- LOC corpus: 197 pages from Chronicling America queries.
Most LOC pages appear unrelated to Thomas H. Moray (common word matches like “Moray” the eel or Moray Firth). UDN pages remain the most promising for contemporaneous coverage.
Why This Ledger Exists
The archive uses a strict evidentiary boundary. Until a claim is tied to a primary document, it remains an unverified lead or interpretive synthesis.
