Countess Ilona Edelsheim-Gyulai de Marosnémethi et Nádaska (14 January 1918 – 18 April 2013)[1][2] was a Hungarian noblewoman and wife of István Horthy, son of Regent Miklós Horthy and Deputy Regent of Hungary for a short time in 1942.
She was born in Budapest, Austria-Hungary, the third daughter of Count Lipót Edelsheim-Gyulai and Gabriella Pejacsevich (Croatian: Gabriela Pejačević).
She spent her childhood in Felsőelefánt (today: Horné Lefantovce, Slovakia), the family's estate in the former Upper Hungary, though during her early life it was part of Czechoslovakia.
After the unsuccessful desertion attempts and Operation Panzerfaust, she emigrated with her father-in-law, the Regent.
She wrote her memoir with the title of Becsület és kötelesség ("Honor and Duty").
