Alternative timeline
In an alternative timeline accidentally created by Jamie in 1688, the Glorious Revolution was a failure and James II remained on the throne until his death. His grandson Charles Edward Stuart, better known as Bonnie Prince Charlie, eventually ascended the throne as King Charles III. He was still the reigning monarch in 1788.
