Antonia de Ipeñarrieta y Galdós y su hijo don Luis Diego Rodriguez De Silva y Velazquez (1599-1660)

The picture has something of this: portrait, people, wear, woman, girl, child, jewelry, fashion, model, necklace, lid, son, dress, veil, two, man, winter, costume.
Perhaps it’s a painting of a woman in a black dress and a small child in a white dress are standing next to each other in front of a chair.
