Following her marriage to the duke, Mary Panton's father Thomas obtained the post of Master of the King's Running Horses,[3] and his son, also Thomas, later inherited this position.
In 1757, Sir Joshua Reynolds painted the couple, and another portrait by Reynolds of the duchess was painted between 1765 and 1771. A watercolour miniature, by John Smart, dating to 1763, is held by the Nelson-Atkins Museum of Art.[4]
