Portrait of Maria Walpole, Duchess of Gloucester (c.1766–69). Nathaniel Dance-Holland (British, 1735–1811). Oil on canvas. Virginia Museum of Fine Arts.
The portrait suggests domestic and marital harmony; however the marriage took place in secret without the permission of the king who never accepted the fact that his brother had married an illegitimate woman, who was also a widow and a commoner. The Duchess was never accepted at court and the marriage was partly responsible for the Royal Marriages Act of 1772, which gave the king the right to veto any royal marriage that he found undesirable.
