Kristina Augusta von Fersen (1754-1846), spouse of Fredrik Adolf Löwenhielm * Gustaf Lundberg (1695-1786)

The picture has something of this: portrait, people, woman, necklace, jewelry, dress, wear, vintage, retro, girl, lace, fashion, model, veil, queen.
Perhaps it’s a painting of a woman in a red dress with a bun in her hair and a braid.
