She was born
Amy Lyon on April 26, 1765, in
Ness near Neston, Cheshire, England, the daughter of Henry Lyon, a blacksmith She later went by the name of
Emma Hart. Fetherstonhaugh took Emma there as a mistress, but frequently ignored her in favour of drinking and hunting with his friends. Emma soon befriended the Honourable
Charles Francis Greville (1749–1809). It was about this time (late June-early July 1781) that she conceived a child by Fetherstonhaugh. As a young woman, Emma's daughter saw her mother frequently, but later when Emma fell into debt, her daughter worked abroad as a companion or governess. Greville kept Emma in a small house at Edgware Row,
Paddington Green, London, at this time a village on the rural outskirts of London. At Greville's request, she changed her name to "Mrs Emma Hart", dressed in modest outfits in subdued colours and eschewed a social life. He arranged for Emma's mother to live with her as housekeeper and chaperone. Greville also taught Emma to enunciate more elegantly, and after a while, started to invite some of his friends to meet her. Seeing an opportunity to make some money by taking a cut of sales, Greville sent her to sit for his friend, the painter
George Romney, who was looking for a new model and muse. It was then that Emma became the subject of many of Romney's most famous portraits, and soon became London's biggest celebrity. So began Romney's lifelong obsession with her, sketching her nude and clothed in many poses that he later used to create paintings in her absence. Through the popularity of Romney's work and particularly of his striking-looking young model, Emma became well known in society circles, under the name of "Emma Hart". She was witty, intelligent, a quick learner, elegant and, as paintings of her attest, extremely beautiful. Romney was fascinated by her looks and ability to adapt to the ideals of the age. Romney and other artists painted her in many guises, foreshadowing her later "attitudes". In 1783, Greville needed to find a rich wife to replenish his finances, and found a fit in the form of eighteen-year-old heiress Henrietta Middleton. Emma would be a problem, as he disliked being known as her lover (this having become apparent to all through her fame in Romney's artworks), and his prospective wife would not accept him as a suitor if he lived openly with Emma Hart. To be rid of Emma, Greville persuaded his uncle, Sir
William Hamilton, British Envoy to Naples and younger brother of his mother, to take her off his hands. Greville's marriage would prove useful to Sir William, as it relieved him of having Greville as a poor relation. To promote his plan, Greville suggested to Sir William that Emma would make a very pleasing mistress, assuring him that, once married to Henrietta Middleton, he would come and fetch Emma back. Sir William, then 55 and newly widowed, had arrived back in London for the first time in over five years. Greville did not inform Emma of his plan, but instead in 1785 suggested the trip as a prolonged holiday in Naples while he (Greville) was away in Scotland on business, not long after Emma's mother had suffered a stroke. Emma was thus sent to Naples, supposedly for six to eight months, little realising that she was going as the mistress of her host. Emma set off for Naples with her mother and Gavin Hamilton on 13 March 1786 overland in an old coach, and arrived in Naples on her 21st birthday on 26 April.
