Administrative / Biographical History

Tre-wyn, Monmouthshire, was originally owned by the Wynston family. In 1606, Thomas Wynston of Tre-wyn sold the manor and estate to John ap William Parry of Wern-y-cwm in Llanvetherine. In July 1609, he conveyed the manor of Tre-wyn (also known as Wynston) to John Delahay of Allt-yr-ynys for the sum of £950. The last member of the Delahay family, Thomas Delahay, died in 1738 without issue. He left the estate to Mary Clerk, wife of Josias Clerk, of Herefordshire, mercer, with remainder to their second son, Josias, and in default to their eldest son, John, on the condition that the inheritor took the name of Delahay. In 1745 the estates were purchased by William Kynaston, who sold off parts of it. In 1748 the manor of Tre-wyn was sold off after the death of Kynaston to James Shaw. On James's death in 1767 the estate was left to his great-nephew, William Shaw. William Shaw died in 1772 and Jeremiah Rosher, who married the widow of William Shaw, purchased the estate. In 1895, Jeremiah Lilburn Rosher sold the manor and estate to Philip Bartholomew Barneby.
