"1860s ... the boy is deceased" NO. Standing post mortems are an urban legend. Stands were used to steady people for long exposure times used in photography at that time. It's impossible to prop up a dead person in this fashion! The stand couldn't hold up that much 'dead weight', the mouth would hang open, and the head and limbs would flop down. Could a person even hold up a dead child and have her look natural? No, and a stand can't do it either!
