Catherine Worlee (1762-1835) Duchess of Talleyrand-Perigord Francois Pascal Simon Gerard (1770-1837)

The picture has something of this: people, veil, woman, Renaissance, princess, wear, royalty, dress, seat, monarch, portrait, two, queen, bonnet.
Perhaps it’s a painting of a woman in a white dress standing in front of a table in a room with a green couch and a red rug on the floor.
