On his return, in 1775, Romney moved to Cavendish Square, in a house formerly owned by noted portraitist Francis Cotes. He was considerably in debt, not only on his own account but also due to being saddled with the debt of his artistic but dissolute brother Peter. However, he was offered commissions by the Duke of Richmond and his circle of friends, which helped turn the tide of fortune permanently in the artist's favour. In 1776–77, he made the acquaintance of William Hayley, striking up a lasting friendship with the writer, and painting portraits for him.
