The POD here is that Lady Anne Neville falls pregnant in 1471, with Edward of Westminster’s child, and following the Lancastrian defeat, dies giving birth to a stillborn child. Now what? Who does Richard, Duke of Gloucester (later Richard III) marry here? Cecily Bonville seems likely IMO, but a Scottish Princess is also possible. Would George still rebel if he’s inheriting the bulk of the Neville lands?
