What about all the country music songs about the dead girlfriend/wife/kid? There also was a bunch of dead girlfriends songs in the early years of rock. (For instance, the one where the car stalls on the train tracks and the stupid bimbo goes back for the guy's ring...)
In order for the children to stay still long enough to be photographed, the mother sat with them covered by a large table cloth or something on that order. Why the mother couldn't be shown as herself is beyond me.
It was because photographers generally charged for each subject as well as each shot.
