Disproven theories
Corrections to our own pages, kept so the record stays honest. Each entry gives the fact first, then what we stated earlier, why it was wrong, and when we corrected it, with links to the corrected pages.
A statement enters this register only when a record contradicts it. Questions the records leave open, such as the two dates given for the demolition in 1988, stay in the register of what the records don’t say.
Parcel A ends before the 1970 village green
- The record shows
- The Parcel A line ends before the green begins. The green is a separate registration: village green VG41, registered by the council in 1970 under the Commons Registration Act 1965 (catalogue EV-0044).
- What we stated earlier
- Our research pages and the infographic “The Land Changing Hands” showed Parcel A split into three parts, with the green as the third, and the research layer placed the green on the “south-east ground of Parcel A”. Shown on the infographic and in the Research Library until 27 October 2026.
- Why it was wrong
- The family’s marked-up Ordnance Survey plan of the holding draws the Parcel A line round the farmstead, with its south edge along the lane north of St Dochdwy’s Church, stopping short of the green. The certified register map shows the green as a small roadside wedge (catalogue EV-0263). Our pages had merged two separate registrations into one parcel.
- The fact
- Parcel A and the 1970 green are separate: the green lies outside the Parcel A line.

No Roman villa in the Iron Age scene
- The record shows
- In the period of the documentary’s second scene, the earliest structure found south of the church is a possible late Iron Age roundhouse, perhaps part of a farmstead (excavations of 1979). The Roman villa came later, in the 2nd century AD (Owen-John, H.S. 1988, “Llandough: the rescue excavation of a multi-period site near Cardiff, South Glamorgan”).
- What we stated earlier
- The second scene of our documentary, set in the Iron Age, showed and spoke of a Roman villa (scene F002, first cut).
- Why it was wrong
- The villa belongs to a period about three centuries after the scene. Showing it in the Iron Age put a later building into an earlier time.
- The fact
- Iron Age Llandough had a roundhouse farmstead, not a villa.
- Corrected
- 27 October 2026 (script corrected; the scene is being re-made with Iron Age people speaking Welsh about everyday life). Pages changed: The documentary
The farm stood inland, on a hill
- The record shows
- Tŷ Mawr stood inland, on the hill at Llandough above the River Ely: H.J. Thomas measured plan and sketch, NGR ST 1680 7331, 26 April 1974 (RCAHMW NA/GL/89/208).
- What we stated earlier
- Our documentary script placed Sutton “on the coast” (scene F005), and early drafts of the film’s settings gave the hill a coastal setting.
- Why it was wrong
- The grid reference and the 1974 survey place the farm inland; Sutton lies down the Vale, not on the coast.
- The fact
- The farm and the hill are inland, above the Ely valley.
- Corrected
- 27 October 2026 (script line now reads “Sutton, down the Vale”). Pages changed: The documentary
A modern floor plan belongs to another property
- The record shows
- The modern “Proposed Ground/First Floor” house plan is of another property, outside the Tŷ Mawr scope. It is parked for later inspection as Kissed Frogs KF-49.
- What we stated earlier
- The plan arrived among the Tŷ Mawr archive images on 27 October 2026 and was first read with them as Tŷ Mawr material.
- Why it was wrong
- It shows none of the rooms of the 1974 measured plan of Tŷ Mawr (Hall, Passage, Kitchen, Dairy; RCAHMW NA/GL/89/208).
- The fact
- The plan is not a Tŷ Mawr record.
- Corrected
- 27 October 2026. Pages changed: KF-49 · Kissed Frogs
