Forensic Assessment — Debenham Tewson#

Scope: the historical professional firm as surveyor/estate agent/valuer/auctioneer where the case record places it in a relevant transaction. Legal responsibility is not inferred from the firm’s professional category.

New contextual finding#

Contemporary records establish that Debenham Tewson firms operated as surveyors, estate agents, valuers and auctioneers. That makes the firm’s exact role in any Great House Farm valuation, sale, plan or auction material a concrete identity question rather than a generic assumption.

Forensic control test#

Identify the precise entity, date, client and document. For any Great House Farm material, determine whether the firm prepared sale particulars, valuation, plan, auction instructions or other representation about the property extent.

Current finding#

As at 10-10-2026, the material reviewed does not establish wrongdoing by the actor under review. This is a source-limited assessment, not a timeless finding of non-involvement. The evidential value is potentially high if a surviving professional plan or valuation records the farmhouse/fields distinction or the party from whom title was said to derive.

Human action#

Search Glamorgan Archives, The National Archives and relevant professional records for Great House Farm/Tŷ Mawr/Llandough, the 1938 sale, 1924 sale and associated plans. Capture the exact entity name and professional capacity.

Acceptance: every relevant Debenham Tewson document is identified, sourced and classified as title evidence, plan evidence, valuation evidence or context.

Institutional appearance timeline — linked source index#

Coverage rule: this is a chronological navigation map of published Wiki source pages found by searching the current site index for “Debenham Tewson”. Every event label links directly to the page containing the source. The page is intended to avoid duplicating source narratives. It records mention/appearance, not culpability. The displayed date is a source/title date cue, not automatically the date on which the named institution acted. This matters for newspaper stories, later summaries and titles naming more than one event; open the source before attributing an act. Search indexing is a discovery aid, not proof of exhaustive coverage. 🕒
