Isabel of Beira
It was planned that she would marry Victor Amadeus II of Savoy, a first cousin through her aunt Marie Jeanne, Duchess of Savoy, then regent for her son. The marriage was opposed by most of the Savoyard court as it meant that Victor Amadeus would live in Portugal and his mother would remain in power. But that plan was not implemented.
On 1686, the marriage proposal of Gian Gastone de Medici and Isabel of Beira was approved and she left for Tuscany.
