Roundell Palmer, Marriage with a Deceased Wife's Sister… (1873)
“ Is it possible, and would it be safe, that a husband should treat a wife's sisters as his own if he were allowed to marry them? And would not children suffer as well as husbands and wives? What is the real meaning of the argument that wives' sisters would prove the best stepmothers the children could have? It means that the wife's sister is the children's aunt, and is likely to bear them a closer affection than a stranger. Nothing can be more true under a law which does not invite her to become their stepmother. ”
