"A Manchu official and presumably his wife and son. Others have reported this scene (erroneously, IMHO) as "Wedding photo of the late Qing Dynasty." If so, the bride would be veiled and we would never see her face, nor would there be the existence of a son yet. The woman is wearing a Single Tooth pedestal shoe and did not bind her feet; that means she was Manchu. Since Manchu could not intermarry with Han, that meant her husband too was Manchu. Hence, a Manchu family portrait, IMHO."
