James wasn't off the hook; in the same year, after his Catholic second wife gave birth to a son (the future "bonny prince Charlie")

I think you'll find King James IIs son was James, the 'Pretender' to the throne, who was responsible for the 1715 uprising. (Perhaps not responsible enough?)
Bonny Prince Charlie, the 'Young Pretender' was the next generation and took part in the 1745 uprising on behalf of his father (who in fact, never quite made it).
