"Penelope Ligonier, née Penelope Pitt (1749–1827), was an English aristocrat and socialite, and first wife of Edward Ligonier, Earl Ligonier of Clonmell.
She was the eldest daughter of Penelope Atkins (c. 1724 – 1795) and George Pitt, 1st Baron Rivers. Both her parents were 'noted for their extraordinary physical beauty', but their family life was unhappy due to her parents' turbulent marriage. Horace Walpole, an admirer of Penelope Atkins, alleged that George Pitt 'had heaped on her every possible cruelty and provoking outrage', and alleged that after their separation he prevented her from seeing their four children." - (Wikipedia (en) 29.05.2022)
