Yolande of Aragon or Violante of Sicily (Kingdom of Sicily – 1428, Italian: Jolanda d'Aragona, Catalan: Violant d'Aragó, Spanish: Violante de Aragón) was the legitimized daughter of King Martin I of Sicily and countess of Niebla.
Eugénie de Montijo, the last Empress consort of the French, was descended from her.
[1] She was the only daughter of King Martin I of Sicily and Sicilian noblewoman Agatuccia Pesce.
Before Blanche I of Navarre arrived in Sicily to be married to her father, the king sent her and her younger brother Fadrique (illegitimate son of Martin I and Tarsia Rizzari) to the Aragonese court to be reared in the care of the king's mother, Queen Maria de Luna.
[3] Her second marriage was to Martín Fernández de Guzmán, son of Alvár Pérez de Guzmán, 6th Lord of Orgaz.
