I was reading about the Restoration of the Stuarts and I've found an interesting fact: the same year that the monarchy was restored (1660) two of the sibblings of Charles II died from smallpox after going back to England - princess Mary and Henry, Duke of Gloucester. So, WI both Charles and James were as unlucky as their sibblings and had also got smallpox and died after arriving in England? How would the death of the Stuarts affect English politics? Also, considering that the legal heir would be the 10 years old William of Orange, would he be recognized as king?
