Sir William Williams, 2nd Baronet, of Gray’s Inn
Sir William Williams, 2nd Baronet (c. 1665 – 20 October 1740) was a politician in the United Kingdom Great Britain. He was Member of Parliament (MP) for Denbigh from 1708 to 1710.
His father, the 1st Baronet, was Speaker of the House of Commons.
He married Jane Thelwall, the great-granddaughter of Sir John Wynn, 1st Baronet. Her relative Sir John bequeathed the entire Wynnstay estate to her; since he and Sir William Williams were the two largest landowners in north Wales at that time, together the combined estate dwarfed all others. In honour of his wife’s ancestry, Sir William changed his name to Sir William Williams-Wynn of Wynnstay.
