James II and Charles II of England had a brother,Henry of Oatland. Henry was a staunch Protestant and a good soldier. However, he died in 1660, aged 20 years old. Later, he was remembered as 'a lost light'.
I have 3 ways to make Henry of Oatland become King Henry IX:
1- Catholic James II is bypassed in favour of Henry in 1685.
2-In 1689, the Glorious Revolution leads to Henry becoming King.
3-After the death of Queen Anne, Henry or his issue becomes the monarch of England.
Which is the most plausible and what effects will this have?
