EV-0017 — Glamorgan Archives DSA/12/5400: Llandough Farm (Ely Tidal Harbour), J. M. Williams — a different farm

Outside records

How we treat outside records. Tŷ Mawr is first named in the record we have found in David Stewart’s 1824 survey (EV-0211). The Williams family acquired Tŷ Mawr in 1667 (sources: Mary Williams’ statement in the 1974 newspapers; ITV News, 1988). Earlier documents on this page that come from the Bute estate or other third parties, such as the Cydwin lease or a Bute catalogue heading, are not records of Tŷ Mawr: their application to it is under forensic examination, and we test them rather than repeat them. Our methodMae Tŷ Mawr wedi’i enwi gyntaf yn y cofnod a gawsom yn arolwg David Stewart, 1824. Cafodd teulu Williams Dŷ Mawr yn 1667 (ffynonellau: datganiad Mary Williams yn y papurau newydd, 1974; ITV News, 1988). Nid yw dogfennau cynharach gan ystâd Bute neu eraill yn gofnodion o Tŷ Mawr; maent dan archwiliad fforensig.Tŷ Mawr aparece nombrado por primera vez en el registro que hemos hallado en el catastro de David Stewart de 1824. La familia Williams adquirió Tŷ Mawr en 1667 (fuentes: declaración de Mary Williams en la prensa de 1974; ITV News, 1988). Los documentos anteriores de la finca Bute u otros terceros no son registros de Tŷ Mawr; están bajo examen forense.

Does not prove: Its “J. Williams” is not John Williams of Great House Farm; Recorded here as a name trap.
