Ladies of Llangollen Newydd is now a museum run by Denbighshire County Council. Butler's Hill, near Plas Newydd, is named in honour of Eleanor Butler.

Ladies of Llangollen The "Ladies of Llangollen", Eleanor Butler and Sarah Ponsonby, were two upper-class Irish women whose relationship during the late 18th and early 19th century scandalized and fascinated their contemporaries. Eleanor Charlotte Butler (11 May 1739 – 2 June 1829) was a member of the Butlers, the Earls (and later Dukes) of Ormond.
Maria Ponsonby, Viscountess Duncannon Maria Ponsonby, Viscountess Duncannon Maria Ponsonby, Viscountess Duncannon (11 May 1787 – 19 March 1834), formerly Lady Maria Fane, was the wife of John Ponsonby, 4th Earl of Bessborough. She died before he inherited the earldom and thus was never Countess of Bessborough, but three of her sons were successively earls of Bessborough. She was the daughter of John Fane, 10th Earl of Westmorland, and his first wife, the former Sarah Anne Child. Her brother was John Fane, 11th Earl of Westmorland, and her sisters were Sarah Villiers, Countess of Jersey (1785–1867), Lady Augusta Fane (1786–1871; later Lady Boringdon) and
