Foix, Count of Comminges; and Hélène d'Albret (16 July 1495- 28 October 1519). She had two illegitimate half-siblings, Jacques d'Albret, Bishop of Nevers, and Françoise d'Albret, Abbess of Notre Dame de Nevers. Her paternal grandparents were Arnaud Amanieu d'Albret, Sire d'Orval (died 1463) and Isabelle de
