Wynnstay is situated in the parish of Rhuabon, and is erected on the site of a residence of Madog ab Grufydd Maelor, Prince of Powys, and founder of the abbey of Llanegwest, or Valle Crucis, near Llangollen. The original name of this house was _Rhuabon_. It was the property of Edward Eyton, Esq., whose daughter Mary, the heiress, married Richard Evans, Esq., son of Thomas Evans, Esq., of Oswestry, attorney-general in the Court of the Marches. Their grandson, Eyton Evans, (son of Thomas, son of Richard,) altered the name to _Watt_-stay, on account of its proximity to Watts’ Dyke; and Jane, sole daughter and heiress of Eyton Evans, Esq., married Sir John Wynn, who again changed the name to _Wynnstay_, in compliment to his own family, he being grandson of Sir John Wynn, of Gwydir, by his tenth son, Henry, representative for Merionethshire. The above-named Sir John Wynn, of Wynnstay, left that and other estates of great value to his kinsman, the first Sir Watkin Williams Wynn, grandson of Sir William Williams, Speaker of the House of Commons in the reign of Charles II., and in the early part of his career Recorder of Chester. Sir William was one of the most successful lawyers of his time, and was a zealous and eloquent advocate of the popular party in Charles’s reign. The notorious Jeffreys was reprimanded, on his knees, by him whilst he was Speaker of the House of Commons; who also conducted the prosecution of the Seven Bishops, when solicitor-general; and the “Treating Act,” which still continues one of the safeguards of the purity and independence of Parliament, was introduced by him in the House of Commons. This celebrated lawyer was made a baronet in 1688. He married Margaret, daughter and heiress of Watkin Kyffin, Esq., of Glascoed, in the parish of Llansilin, near Oswestry. He left two sons, and the elder, Sir William, of Llanforda, married another great heiress, Jane, the daughter of Edward Thelwall, Esq., of Plas-y-ward, and was father, as already mentioned, of the first Sir Watkin Williams Wynn. The Speaker’s youngest son, John, was an eminent provincial lawyer, and practised at Chester, and was direct progenitor of the present Sir John Williams, of Bodelwyddan, Flintshire.
