The story has been scattered because the place has so many names.

• The house and the farm: every form, from the catalogue headings to the Land Registry’s “Ty Mawr Farm”.
• The town and the parish: the two Llandoughs, and the Ordnance Survey’s mix-up of October 2026.
• The estate and the parcels: Cwm Cydfin, the woods, the green, Parcels A and B, title and plan numbers.
• Plays on names and dates: where a catalogue heading, a lookalike name or the wrong Llandough has carried a meaning the record does not support.

Tŷ Mawr is first named in the record we have found in David Stewart’s 1824 survey of the Bute Glamorgan estates. The Williams family acquired Tŷ Mawr in 1667 (Mary Williams’ statement, 1974 newspapers; ITV News, 1988). Bute and other third-party papers dated before 1824 are listed with their dates and sources and are under forensic examination; how we treat outside records.
