Administrative/Biographical history: Mathew Evans, a solicitor and twice mayor of Aberystwyth (1734 and 1760) is the first recorded occupier of Cwmcynfelyn. He left his estate to his nephew, Mathew Davies of Wileirog-uchaf (sheriff of Cardiganshire in 1790). Mathew Davies married Jane, daughter of Roderick Richards of Plas Penglais, Aberystwyth, and had two daughters and co-heiresses. Jane, the eldest, married Isaac Lloyd Williams (1771-1846) of Lincolns Inn, the son of David Williams of Ty'n-y-wern and Ystrad Teilo in the parish of Llanrhystud, Cardiganshire. Isaac was succeeded by his eldest son, Mathew Davies Williams (1800-1860), who sold parts of the estate to the Gogerddan estate. Cwmcynfelyn appears to have passed out of the hands of the Williams family by 1881.


Scope and content/abstract: Family papers and estate records of the Williams family of Cwmcynfelyn, Cardiganshire, comprising rentals, 1833-[1885], valuations, [1849]-1879, financial papers, 1826-1899, deeds of the Cwmcynfelyn estate in north Cardiganshire, and in the parish of Machynlleth, Montgomeryshire 1773-1886, deeds relating to Penpompren in Llanfihangel Genau'r-glyn, 1724-1791 (including a schedule of deeds dating back to 1694) which probably found their way to Cwmcynfelyn through the marriage of Matthew Davies Williams of Cwmcynfelyn and Susanna Griffith in 1828; papers relating to the Donisthorpe and Mapperley collieries, Leicestershire, 1874-1899; papers relating to the Gogerddan estate, Cardiganshire, accumulated by George Griffiths Williams as agent until his retirement, 1852-1895; and personal papers of Mathew Davies Williams, 1821-1864.
