Administrative / Biographical History

In the 15th century Cillwch manor, Monmouthshire, was held by William, 1st Earl of Pembroke. Soon after it was in the possession of David ap Thomas ap Gwilym, uncle of the Earl of Pembroke, and continued as a seat of his descendants for six generations. William Hughes, the last descendant, left Cillwch estate to his daughter, Lucy, who married George Morgan of the Garn. They died without issue and a cousin of George Morgan, Anthony Powell (d. 1692), became settled at Cillwch. Anthony left Cillwch to his nephew, Francis Powell, who seems not to have possessed it. It was held by Lord Gerard in right of his first wife, Elizabeth, only child of Anthony Powell. On the death of Lord Gerard in 1711, the Duke of Hamilton, who had married the only child of Lord Gerard by his second wife, took possession of Cillwch, but had to relinquish it following a lawsuit by Anthony Powell (d. 1742), nephew of Anthony (d. 1692). Soon after regaining Cillwch, the Powell family sold the estate to Thomas Medlycott (d. 1738), agent to the Duke of Beaufort, probably between 1711 and 1720. Thomas Medlycott was the founder of the Irish branch of the family - in Rockett's Castle, County Waterford. It was held by the Medlycott family until James Thomas Medlycott of Dublin, and grandson of Thomas Medlycott, sold the estate to John Lewis of Llantilio in 1770. It then formed part of the Llantilio estate.
