Administrative and biographical history: The Williams family acquired the Llangibby Castle estate (anciently called Tregrug) following the purchase of the estate by Roger Williams (d. 1585) of Usk in 1544-1545. He was succeeded by his son, Rowland Williams, followed by his son Charles Williams, who became M.P. for Monmouthshire in 1621. He was succeeded by his son Sir Trevor Williams who played a prominent role in the Civil war in Monmouthshire, siding first with the King, then with the Parliamentarians before rejoining the royalists in 1648.
The estate remained in the hands of the Williams family until the death of Sir John Williams without male issue in 1739. His daughter Ellen (1724-1781/2), who inherited the estate, married William Addams of Monmouth who assumed the additional surname of Williams.
