OK lets say the '45 rising is a success and James III is restored to the thrones of the British Isles (lets not debate how or if its possible please). Charles, Prince of Wales and Henry, Duke of York are now some of the most eligible bachelors in Europe (and potentially James III, if he choose to take a second wife); so who would be potential brides for the English royals?
I figured that Princesse Henriette de France would be the most likely bride for the Prince of Wales (a match with a French Princess was considered OTL) but who else would be considered? A Princess from Scandinavia (Louise of Denmark, b. 1726) or the German States (Anna Amalia of Prussia b.1723, Maria Antonia of Bavaria b. 1724, Maria Anna Sophia of Saxony b. 1728)?
And what about the Duke of York? No chance he'd become a Cardinal or be allowed to be celibate here. I'd thought of Maria Antonia Ferdinanda of Spain (b. 1729) as the best candidate but I'd guess that any of the above candidates for Princess of Wales would also work for Duchess of York.
Any other candidates I've missed or other ideas?
