Just an idea I was thinking about, using two possible PODs: suppose that James II contracts some disease or infection (POD 1) by the time Mary of Modena was pregnant. If she dies during the labor (POD 2), and the king also dies not much later (let's say one or two days later), but the baby is alive and healthy, what happens with the succession? Would William and Mary still go to England, or the English government would think more interesting the idea of an infant king that could be controlled for many years to come?
