Yolande of Aragon, Countess of Niebla
Yolande of Aragon or Violante of Sicily (Kingdom of Sicily – 1428, Italian: Jolanda d'Aragona, Catalan: , Spanish: ) was the legitimized daughter of King Martin I of Sicily and countess of Niebla. She was a member of the House of Barcelona. Eugénie de Montijo, the last Empress consort of the French, was descended from her. Life
She was the only daughter of King Martin I of Sicily and Sicilian noblewoman Agatuccia Pesce. She was born out of wedlock in Sicily. 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. She was twice married. Her first husband was Enrique Pérez de Guzmán, 2nd Count de Niebla, whom she married in 1405. This marriage produced no issue and was annulled. Her second marriage was to Martín Fernández de Guzmán, son of Alvár Pérez de Guzmán, 6th Lord of Orgaz. She gave birth to three daughters. She died in 1428. Issue
