|Marguerite Gardiner, Countess of Blessington
(1 September 1789 – 4 June 1849)
Marguerite later moved to Hampshire to live for five years with the family of Thomas Jenkins, a sympathetic and literary sea captain. Jenkins introduced her to the Irishman Charles John Gardiner, 1st Earl of Blessington, a widower with four children (two legitimate), seven years her senior. They married at St Mary’s, Bryanston Square, Marylebone, on 16 February 1818, only four months after her first husband’s death.
Of rare beauty, charm and wit, she was no less distinguished for her generosity and for the extravagant tastes she shared with her second husband, which resulted in encumbering his estates with debt. On 25 August 1822 they set out for a continental tour with Marguerite’s youngest sister, the 21-year-old Mary Anne, and servants. On the way they met Count D’Orsay (who had first become an intimate of Lady Blessington in London in 1821) in Avignon on 20 November 1822, before settling at Genoa for four months from 31 March 1823. There they met Byron on several occasions, giving Lady Blessington material for her Conversations with Lord Byron.
After that they settled for the most part in Naples, where she met the Irish writer Richard Robert Madden, who was to become her biographer. They also spent time in Florence with their friend Walter Savage Landor, author of the Imaginary Conversations which she greatly admired.
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 newly-wed 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. Their home, first at Seymour Place, and afterwards Gore House, Kensington, now the site of the Royal Albert Hall, became a centre of attraction for all that was distinguished in literature, learning, art, science and fashion. Benjamin Disraeli wrote Venetia whilst staying there.
After her husband’s death she supplemented her diminished income by contributing to various periodicals as well as by writing novels. She was for some years editor of The Book of Beauty and The Keepsake, popular annuals of the day. In 1834 she published her Conversations with Lord Byron. Her Idler in Italy (1839–1840), and Idler in France (1841) were popular for their personal gossip and anecdotes, descriptions of nature and sentiment.
Early in 1849, Count D’Orsay left Gore House to escape his creditors; subsequently the furniture and decorations were sold in a public sale successfully discharging Lady Blessington’s debts. Lady Blessington joined the Count in Paris, where she died on 4 June 1849 of a burst heart. On examination it was found that her heart was three times normal size.
