Great House Farm — Nomenclature & Identity Map

One research subject — with nearby same-name farms kept separate

This page is the Wiki’s visual identity-control map. The research subject is Great House Farm / Tŷ Mawr at Llandough-juxta-Penarth, beside St Dochdwy’s Church. Do not merge it with the separate Llandough Farm opposite the hospital. Both are in the same Llandough near Penarth/Cardiff locality, but they are different farmsteads. “Church Farm / Llandough Church Farm” is also shown as a source-specific, unresolved term, not as an alias of Great House Farm. ^🕒

Controlling parcel definition — 9 October 2026. Parcel A is the full 1877 house/quarrying estate: farmhouse/buildings, barn, stable and yard west of the house, garden, forest north of the house, and ground south-east of the house/garden later registered as VG41. Parcel B is the separate eastern agricultural fields. The family’s established title case is that the 1877 arrangement took effect in 1928. [SOURCE PENDING] WGR’s 4 July 1955 enforcement of Parcel B also seized the Parcel-A north forest and south-east green under “whole farm” wording. Mary’s later defence of the occupied house group does not narrow the full Parcel-A boundary.

What the colours are doing

• Blue = house/building layer. These are names and descriptions attached to the farmhouse or its property/building identity.
• Purple = combined farm layer. “The farm”, “whole farm” and “the whole farm” describe the combined holding where the evidence supports that reading.
• Green = the full Parcel A. House/buildings, barn, stable and west-side yard, garden, north forest, and south-east green ground later registered as VG41. Gold = Parcel B. The separate eastern agricultural fields.
• Terracotta = locality layer. These place the site inside different historical or modern geographical frames.
• Grey = institutional controls. These are identifiers rather than alternative names.
• Dashed boxes = qualification. A dashed box means the connection is qualified, unresolved, or should not be treated as a clean synonym. ^🕒
• Red perimeter = false friends. They are shown precisely so that a researcher can see what looks similar but must stay separate.

The ambiguity in one sentence

One historical site can be called by a building name, a property/farm name, a parcel description, or a locality name — and a single document can move between those levels without announcing that it has changed level.

That is why the Wiki keeps separate controls for the Farmhouse, Building, Location, Parcel A, Parcel B and Whole Farm — while this page shows how easily the six layers collide in practice.

Research rule: follow the wording of the source first; resolve the identity second. Never allow a familiar name to do the work of a title, plan, grid reference, deed, HER record or other independent identifier.

Cross-reference — Cedwyn / Cydfin place-name evidence: References on this page to variants such as Cedwyn, Cydfin, Cedfin, Cydwin or Tŷ Mawr should be read alongside the GHF-E173 complete reference index and, where relevant, the Llandough (Penarth) pre-1877 manorial evidence page. Name similarity is a research lead, not proof of identical location, boundaries, ownership or title.

Site-wide working-theory cross-reference (18 October 2026): See the Cedwyn Estate Working Theory. This page may contribute evidence to a specific part of that hypothesis only to the extent its source actually establishes a relevant name, event, parcel, title, claim or decision. Similar names, proximity, chronology or institutional involvement are research leads, not proof of common ownership or coordination.
