Sir John Wynn, 5th Baronet was a Welsh landowner and Member of Parliament.
Background
He was the only son of Henry Wynn of Rhiwgoch, Merioneth and educated at the Inner Temple, 1646. He inherited the Watstay Estate through his marriage to Jane Evans (daughter of Eyton Evans of Watstay), which he renamed the Wynnstay Estate.
Career
He served as High Sheriff of Denbighshire for 1671-1673, as High Sheriff of Caernarvonshire for 1674-1675 and as High Sheriff of Merionethshire for 1675-1676. He was Custos Rotulorum of Merionethshire for 1678-1688, 1690-1696 and 1700-1711. Sir John lived into his nineties, mainly residing in London, but died without issue in 1719.
On his death the Wynn baronetcy became extinct and the ancient House of Aberffraw (which claimed direct descent from Rhodri Mawr ap Merfyn in the late 9th century and through him to the legendary line of Brutus) was left without known male issue.
There are also several claims that "lost" relatives such as a supposed Colonel Hugh Wynn who is alleged to have moved to Virginia and raised a family. However, with no clear heir, Sir John bequeathed the entire Wynnstay estate to Jane Thelwall (great-granddaughter of Sir John Wynn, 1st Baronet) who was now married to Sir William Williams, 2nd Baronet (c 1665 – 20 October 1740).
Sir John Wynn and Sir William Williams were the two largest landowners in north Wales at that time and together the combined estate dwarfed all others In honour of his wife"s ancestry Sir William Williams changed his name to Sir William Williams-Wynn of Wynnstay.
The current baronet is Sir David Watkin Williams-Wynn, 11th Baronet (born 1940).
