Administrative and biographical history: Evan ap David appears to have been the first to be described as of the Gnoll. His son David Evans was sheriff of Glamorgan in 1562, and was succeeded by his son Lleisan Evans of the Gnoll (fl. 1602). The estate descended from father to son for another three generations, David Evans, sheriff in 1631, Edward Evans, and Sir Herbert Evans, sheriff in 1661, before the male line failed. In 1686 Mary (d. [pre-1696]) daughter and eventual sole heir of Sir Herbert Evans, married Sir Humphrey Mackworth (1657-1727) of Bentley in the parish of Tardely, Worcestershire, kt, the son of Thomas and Anne Mackworth of Betton Grange, Shropshire. The Mackworth family were originally from Mackworth in Derbyshire, and were of considerable antiquity in Derbyshire and Shropshire. Thomas Mackworth of Normanton was created a baronet 1619. Humphrey Mackworth was succeeded at the Gnoll by his son Herbert Mackworth (1687-1765), who was succeeded by his son Herbert Mackworth (d. 1792), who was created baronet in 1776. His son Robert Mackworth (dsp 1794), 2nd baronet, was succeeded in his baronetcy by his brother Digby Mackworth, 3rd bart, of Glan Usk, Monmouthshire, which became the seat of the Mackworth family. The 2nd baronet bequeathed the Gnoll Castle estate to his widow, who subsequently married Capel Hanbury-Leigh of Pontypool Park, Monmouthshire. Gnoll Castle was afterwards sold to Henry Grant (d. 1831), of Wormley, Hertfordshire. It passed to his son, Henry John Grant (1780-1861), and was sold again after his death. In 1857 it was intended that Gnoll Castle would be used as the college of the Western University of Great Britain. Charles Evan-Thomas of Llwynmadoc was joint owner of the Gnoll estate, 1861-1902.
