Princess Sophia's substantial income, provided from the civil list, had allowed Conroy to enjoy a wealthy lifestyle. The princess died in 1848, leaving only £1,607 19s 7d in her bank accounts despite a lifestyle of savings and low expenses. The Duke of Cambridge and the Duchess of Gloucester had a lawyer write to Conroy demanding that he account for the rest of their sister Sophia's funds, but Conroy simply ignored it. According to Flora Fraser, the most recent biographer of George III's daughters, Princess Sophia had in fact personally spent huge sums on Conroy, including heavy contributions to the purchase prices of his residences and supporting his family in a style he judged appropriate to their position. Conroy ultimately received £148,000 in gifts and money from Sophia.
