Williams-Wynn baronets

The Williams-Wynn Baronetcy, of Gray's Inn in the County of Middlesex in the Baronetage of England, and of Bodelwyddan in the County of Flint in the Baronetage of Great Britain, are two titles held jointly since 1880.

Initially the Williams baronetcy of Greys Inn in Middlesex was created on 6 July 1688 for William Williams, a prominent Welsh politician and lawyer from Anglesey, Wales. He served as Speaker of the House of Commons from 1680 to 1681. The second Baronet represented Denbigh Boroughs in the House of Commons.

Sir Watkin, 3rd Baronet, sat as Member of Parliament for Denbighshire and was a prominent Jacobite. He was the husband of Jane (née Thelwall), great-granddaughter of Sir John Wynn, 1st Baronet, of Gwydir. Sir John Wyn was the direct male heir descendant of the princely house of Aberffraw through his ancestor Owain Gwynedd, and pretender to the title prince of Wales. In 1718, he inherited, through his wife, the Wynnstay estates on the death of Sir John Wynn, 5th Baronet, of Gwydir (see Wynn baronets), and assumed the same year the additional surname of Wynn in honor of his wife's princely heritage and claims as prince of Wales. By the 18th century the Williams-Wynn family had become the largest landowners in north Wales.
