Lady Manners, née Louisa Tollemache (1745-1840) was a daughter of Lionel Tollemache, 4th Earl of Dysart. She married, in 1765, John Manners (1730-1792), eldest son of Lord William Manners (second son of the 2nd Duke of Rutland), and MP for Newark. The couple spent most of their lives at Ham House and the rest at Helmingham Hall, Suffolk. The death of John Manners in 1792 brought the 30,000-acre estate of Buckminster into the Tollemache family. In 1821 Lady Manners succeeded her brother in the Earldom of Dysart and barony of Huntingtower, becoming the 7th Countess of Dysart. She and her only unmarried daughter, Laura, were authorised by royal licence to take and bear the surname and arms of Tollemache instead of Manners. She died at Ham House, aged 95, and was succeeded by her grandson Lionel Tollemache, 8th Earl of Dysart.
