Marie Louise (1791-1847) and the King of Rome (1811-1832) Francois Pascal Simon Gerard (1770-1837)

The picture has something of this: people, wedding, woman, dress, bride, two, princess, veil, wear, girl, portrait, group, room, castle, son, model.
Perhaps it’s a painting of a woman in a white dress holding a baby in a room with a red couch and a green drapes on the window sill.
