So lets say that if Henry VIII has a healthy son and that means that he doesn't want to get a divorce. Thus in turn England maybe stays Catholic. Might that mean Ireland goes Protestant to rebel against the English? Maybe John Knox has success with Presbyterianism there, or maybe we see a homegrown movement if the Church is more on the side of England. I'll admit I don't know much about history in this period other than the basics from high school and college European history, but might it be a plausible scenario?
