Fonds GB 0210 NEUAWR - Neuadd-fawr Estate Records,

The earliest papers in the archive relates to the Maescadog estate, Cynwyl Gaeo, Carmarthenshire. In 1655, this estate was mortgaged to Thomas John Thomas, and again in 1678. John Thomas [John] bequeathed Maescadog to his second son Richard Jones, whose post-nuptial settlement with Mary, only child of David Hugh of Cil-y-cwm, Carmarthenshire, is dated 1682. It is at this point that Maescadog and Neuadd-fawr were joined. By 1694, Richard Jones was living at Neuadd-fawr, but he continued to farm Maescadog. His will was proved in 1713.

He was succeeded by his eldest son, Richard Jones, who married Joan Jones in 1721. Their daughter, Joan, married in 1770, but died without issue. The Neuadd-fawr estate therefore passed to her auntie Joan Jones, daughter of Richard Jones (d. 1713), who had married William David of Maes-Moy, who subsequently appears to have changed his surname to Davys.

The Neuadd-fawr family gained possession of the Dôl-coed estate in Breconshire through the marriage of William Davys and Elizabeth Jones of Dôl-coed in 1765. After her death, William returned to Cencoed in Caeo, and in 1774 married Ann King of Llangathen. Captain Richard Davys of Neuadd-fawr, son of William Davys and Ann King, died without issue. Neuadd-fawr passed to his half-sister, Mary Davys, the daughter of William Davys and Elizabeth Jones. Mary married the Rev. David Harries, rector of Meline, Pembrokeshire. Their son, William Davys Harries Campbell-Davys (b. 1812) on his marriage to Elizabeth Jane Campbell, daughter of Peter Campbell, of Askomel, Kintyre, in 1847, altered his surname to Campbell-Davys. Ivor Elystan Campbell-Davys was living in Neuadd-fawr in 1941.
