The Myddelton family were substantial landowners and benefactors in and around Denbigh in the north-east of Wales.
Richard Myddelton (by 1509–1577/78), the first MP for Denbigh Boroughs, was a son of Fulk Myddelton of Llansannan, himself a younger son of David Myddelton, receiver of Denbigh during the reign of King Edward IV, was for many years governor of Denbigh Castle.
His younger brother was Robert Myddelton, also an MP for Denbigh Boroughs.
[1] The Myddelton Family coat of arms features their motto, "In veritate triumpho" (I triumph in trouth), and can be found over the entrance to Chirk Castle in North Wales, which had been bought by Sir Thomas Myddelton in 1595 for £5,000.
After 400 years of family ownership, the Castle was transferred to the National Trust in 1981, although family members lived at the Castle until 2004.
