Lady Lloyd and Her Son, Richard Savage Lloyd, of Hintlesham Hall, Suffolk Thomas Gainsborough (1727-1788)

The picture has something of this: people, lid, wear, man, two, veil, woman, three, group, royalty, military, weapon, sash, costume, portrait, vintage.
Perhaps it’s a painting of a man and a woman standing next to each other in a wooded area with a bench in the foreground and trees in the background.
