What if Princess Charlotte of Wales, the daughter of George IV of England and her child survived their untimely deaths in 1817? First of all, Queen Victoria would've never been born for their would be no race among George III's sons to produce a legitimate heir, because there would already be two legitimate heirs. Also, could Belgium have been added to the UK as Charlotte's husband IOTL became Leopold I of Belgium and if he does ITTL, their child would be the heir to both the UK and Belgium. Finally, could George IV have lived longer.?
