What would happen if William of Gloucester (Queen Anne of Englands only child to survive infancy) had managed to score a jackpot in the genetic lottery, being generally healthly? (Anna Sophia, her second (living) child, would appear to have been quite healthy, only dying to a smallpox outbreak also claiming her elder sister) For one it would likely cut off the Hanoveran connection leaving England less interested in HRE due to Personal union and it could easily spin into Oldenburgs being seen as a Northern Habsburg by 'evil tongues', but otherwise?
