In otl the 'merry monarch' notoriously fathered many illegitimate children. However his wife did not give birth to a surviving child.
That meant that his heir was James II, who refused to hide Catholicism and was not tolerable to the establishment. Hence 'The Glorious Revolution' (or Dutch coup and invasion if you prefer)
Had there been a son or even a daughter for Charles clearly they would have got the Throne.
Does this weaken Parliament in the 1700s?
Is the Church or England less oppressively established than in OTL (which had laws limiting not only Catholics but other Protestants)?
