When did Margaret Georgiana Spencer's husband die?
Georgiana Spencer, Countess Spencer Margaret Georgiana Spencer, Countess Spencer ("née" Poyntz; 8 May 1737 – 18 March 1814), was an English philanthropist. She was born at St James's Palace as the daughter of a diplomat and a maid of honour to Caroline of Ansbach. In 1754, she married John Spencer, one of the wealthiest men of the era. A love match, the marriage resulted in the births of three surviving children, which included Georgiana Cavendish, Duchess of Devonshire. The Spencers became earl and countess in 1765, a reward granted by the Duke of Newcastle for John's political loyalty to the Whig party.
Mary II, Countess of Menteith Mary II of Menteith was the Countess of Menteith. Her father was Alan II, Earl of Menteith, who died c. 1330. She is believed to have agreed with her kinsman Muireadhach III, in 1330, that he should hold the Earldom, but when he was killed in August 1332, Mary assumed the title. She married Sir John Graham (d. 28 February 1347), who in her right became Earl of Monteith and assumed the title in May 1346. She died sometime prior to 29 April 1360. She was the mother of Margaret Graham, Countess of Menteith.
