Numan, Hermanus – Suzanna Cornelia Mogge (1753-1806). Tweede echtgenote van Hendrik Muilman (1743-1812), 1776 Rijksmuseum: part 3

The picture has something of this: people, seat, furniture, room, woman, child, wear, sit, chair, portrait, lid, group, two, veil, baby.
Perhaps it’s a painting of a woman in a blue dress and a little girl in a pink dress sitting on a chair in a room with a mirror on the wall.
