Family Portrait Jan (Mytens) Mijtens (1614-1670)

The picture has something of this: weapon, people, woman, sword, group, man, gun, rifle, war, music, military, skirmish, wear, soldier, two, costume, veil, instrument.
Perhaps it’s a painting of a man, woman, and child in a wooded area with a dog and a man holding a rifle in one hand and a dog in the other hand.
