Elisabeth-Louise Vigee Le Brun – The Marquise de Pezay, and the Marquise de Rouge with Her Sons Alexis and Adrien National Gallery of Art (Washington)

The picture has something of this: people, woman, two, group, three, furniture, seat, wear, child, affection, portrait, son, reclining, veil, family, facial expression.
Perhaps it’s a painting of three women, one holding a child, and the other holding a young child, in a landscape with a castle in the background.
