The strange life of Lady Blessington1933

"Marguerite Gardiner, Countess of Blessington (1 September 1789 ? 4 June 1849) was an Irish novelist....[She and her husband] met Count D'Orsay (who had first become an intimate of Lady Blessington in London in 1821)... It was in Italy, on 1 December 1827, that Count D'Orsay married Harriet Gardiner, Lord Blessington's only daughter by his former wife. The Blessingtons and the newlywed couple moved to Paris towards the end of 1828, taking up residence in the Hôtel Maréchal Ney, where the Earl suddenly died at 46 of an apopleptic stroke in 1829. D'Orsay and Harriet then accompanied Lady Blessington to England, but the couple separated soon afterwards amidst much acrimony. D'Orsay continued to live with Marguerite until her death."--Wikipedia.
