A Willow-Tree. Study * Pehr Gustaf von Heideken (1781-1864)

The picture has something of this: people, woman, child, baby, girl, son, two, portrait, Mary, dress, wear, three, love, group, man.
Perhaps it’s a painting of a woman, two children, and a dog in a wooded area, with a tree in the foreground and a body of water in the background.
