What if Catherine of Aragon dies after the birth of Mary of England, who does Henry VIII remarry, would he marry Eleanor of Austria, Renee of Ferrara or Claude of France.
No idea who he would marry, but wouldn't this butterfly away the separation of the English Church from Rome? Without the divorce from Catherine business, the relationship between the papacy and the crown wouldn't have been so badly damaged, and the rupture was not an eventuallity.
I would'nt rule out a Scottish princess. Perhaps as a result of the influence of Margaret Tudor in Scottish politics.
Like who?
One of Catherine of Aragon's nieces, sisters of Charles V would have been the most likely candidates.
Eleanor would have been the primary candidate, she was 18 when her aunt Catherine died.
