The oldest sister of Karl V, Holy Roman Emperor, was originally supposed to marry the future Joao III of Portugal. Unfortunately, her prospective father-in-law decided to marry her instead, despite the fact he was her uncle. Eleanor had two children hefore her widowhood and remarriage to the French king. And despite her daughter, Maria, being considered as suitable dauphine material, the proposed match between her and her stepbrother never happened. Thus, Eleanor like her sister-daughter-in-law, Katherina, has no surviving descendants today.
What if Eleanor marries her proposed husband instead of Manuel? How might an not-too-alternate house of Aviz fare? And what of Katherina? She'd be too young for Manuel, and Marie and Isabella were already married. Does Katherine perhaps end up as queen of France? Or does Karl V put James V's proposals for Marie to Katherina instead? Since barring Catherine of Aragon dying early, the Habsburgs won't offer her for queen of England.
