GHF-E173 — Cedwyn / Cwm-Cedwyn: complete reference index

References indexed: Cedwyn / Cwm-Cedwyn / Nant-Cedwyn / Ynys-Cedwyn and related forms. Some entries remain placeholders until the primary source is attached or independently verified.

Identity control: these similar spellings are research leads, not proof that every place-name refers to the same holding or to Great House Farm at Llandough-juxta-Penarth. The link to this property must be tested by source provenance, parish, boundary, acreage, named parties, map/plan and continuity. In particular, “Ty Mawr” can mean “large/great house” in Welsh; that translation alone is not evidence of identity.

Primary evidence family — GHF-E173 to GHF-E179

• GHF-E173 — Cedwyn / Cwm-Cedwyn place-name notes — this index and dependency register.
• GHF-E174 — Nant-Cedwyn — reported brook running into the Ely near Leckwith/Llandough. Primary source pending.
• GHF-E175 — Cwm-Cedwyn — reported wooded dell on the Ely between Leckwith and Llandough. Primary source pending.
• GHF-E176 — Ynys-Cedwyn — place-name associated in the research notes with Cedwyn Gawr and the Twrch–Tawe junction. Location and source attribution need verification; not itself proof of the Penarth farm’s lineage.
• GHF-E177 — 1392 Cwm-Cedwyn boundary reference — reported medieval reference in Llandough boundary records. Primary source pending.
• GHF-E178 — 1547 Cydwin lease — reported 1,000-year lease by Sir George Herbert to Vaughan. Primary source and exact land identity pending.
• GHF-E179 — Bute name variants (first read in 1824) — reported use of “Cedfin/Cydfin/Ken fin Farm or Ty Mawr Farm”. Catalogued as an evidence lead; original entries, their dates and parcel identity must be checked before drawing a lineage conclusion.

What the Cedwyn branch can and cannot support

At present, this branch is a place-name and manorial-history research line. It may help identify older names, holdings or boundaries worth comparing to the later farm; it does not yet prove that all the variants were used for the same land, that the family held the farm continuously from a medieval manor, or that any older lease determines the post-1877 title. Those conclusions require the original records and mapped extents.

Evidence rule: cite the dedicated E-page for a source-specific fact. Cite this index only to navigate the name variants. Where the source is not obtained, cite the appropriate E-page as pending rather than presenting the reported detail as an established historical fact.
