The Rev. and Mrs. Thomas Gisborne, of Yoxhall Lodge, Leicestershire Joseph Wright of Derby (1734-1797)

The picture has something of this: people, two, woman, princess, man, wear, love, Renaissance, portrait, dress, affection, three, narrative, family, girl.
Perhaps it’s a painting of a man and a woman sitting next to each other with an umbrella over their heads and a dog in the foreground of the painting.
