Administrative and biographical history: The Williams family of Aberpergwm are an old family with a very long association with the upper Neath Valley. The family pedigree can be traced back to one Morgan ap Caradoc ap Iestyn, the 12th century lord of Nedd-Afan. The family made Aberpergwm their home in the 16th century, and continued there until the 1950s. The estate consisted in the main of a large area in the parish of Cadoxton-juxta-Neath, principally in the hamlets of Neath Higher and Neath Middle, in the manor of Neath Ultra and Cilybebyll, and adjacent areas in Brecknockshire. Several members of the family were instrumental in cultivating Welsh poetry and music in the Neath Valley, and the house once contained many important Welsh manuscripts. The Williams family were involved in a proactive way with the coal industry, encouraging the growth of the industry to such an extent that Morgan Stuart Williams is described in 1889 as `colliery owner' in preference to the usual `esquire'. According to the 1873 return of owners of land, Morgan Stuart Williams of Aberpergwm, Glamorgan owned an estimated 3,917 acres in Wales (all in Glamorgan and Brecknockshire), with an estimated rental of £3,690.
