She became well known as one of the Lady Patronesses of Almack's Assembly Rooms in London, a prestigious venue during the Regency era. As such, she was described in the Reminiscences of Captain Gronow as "kind and amiable". The earl was a friend of the Prince Regent (the future King George IV) and it was through the Seftons that Maria Fitzherbert, who was related to the earl, first met the prince in 1784. As a senior patroness of Almack's, the countess was well-placed to help Mrs Fitzherbert gain her entrance into London society.[3]
