Lady Eleanor Charlotte Butler was one of the two Ladies of Llangollen, upper-class Anglo-Irish women who lived together in a relationship that scandalized and fascinated their contemporaries. Her companion was the Hon. Sarah Ponsonby (1755-1831), a connection of Lady Caroline Lamb. Eleanor never married, and at some time between 1774 and 1779, she and Sarah Ponsonby decided to live togther in complete isolation from society. Their parents were opposed to the idea, but this barrier was eventually overcome, and the couple purchased a cottage at Plasnewyold, in the vale of Llangollen, Wales, accompanied by a servant. Their devotion to each other, and their eccentric manners, ensured them a wide notoriety. They lived at Llangollen for over 50 years and tourists in Wales sought introduction to them. Prominent British and foreign visitors also were their guests, including Lord Byron and members of the royal Bourbon family. Anna Sewell wrote the poem Llangollen Vale (1796) in their honor; accounts of them can be found in the memoirs of Madame de Genlis. Lady Eleanor and Sarah Ponsonby were both interred in St. Collen's churchyard in Plasnewyold.
