Mary could marry James V of Scotland or an English nobleman here.The Queens take it all!
I know it’s very unlikely, not to say ASB but here it is :
Francis I of France is killed in Marignano in September 1515, leaving a young widow and a newborn daughter.
The new King of France, Charles IX, gets an annulment from the Pope in 1522 and remarries Claude of France.
Little Elizabeth Tudor dies in 1534.
Catherine of Aragon lives another ten years.
Henry VIII dies in the January 1536 tournament and Anne Boleyn miscarries and dies the same month.
Claude of France, Duchess of Brittany (1499-1540) m. a) Francis I, King of France (1494-1515) b) Charles IX, King of France (1485-1535)
1a) Louise of France, Duchess of Brittany (1515-1562)
Henry VIII Tudor, King of England (1491-1536) m. a) Catherine of Aragon (1485-1546) b) Anne Boleyn (1501-1536) p. c) Elizabeth Blount (1500-1540)
1a) stillborn daughter (1510)
2a) Henry, Duke of Cornwall (1511)
3a) son (1513)
4a) son (1514)
5a) Mary I Tudor, Queen of England (1516-1558)

I'm unsure who Louise of France, Mary of England and even the repudiated Margaret of Angoulême would marry here.
