On his return to Naples, Hamilton was lonely. "After having lived 22 years en famille it is most terrible to live chiefly alone", he wrote to his niece. Meanwhile, Greville, who wanted to search for a wealthy wife, was hatching a plan to persuade his uncle to take Emma off his hands. Somewhat reluctantly Hamilton agreed to the plan and Emma arrived in Naples on her 21st birthday, 26 April 1786. With her was her mother, who went by the name of Mrs Cadogan, and who would live with Emma and Hamilton until she died in 1810. The women were installed in an apartment in the Palazzo Sessa, and provided with a carriage and wardrobes. Tutors were hired to give Emma lessons in Italian and singing. It was some months though before Emma accepted the fact that Greville was not going to join her in Naples or send for her to go back to England. At that point she decided to become Hamilton's mistress.
