 Eugenia's older sister, María Francisca de Sales de Palafox Portocarrero y Kirkpatrick, nicknamed "Paca" (24 January 1825 – 16 September 1860), who inherited most of the family honours and was 12th duchess of Peñaranda Grandee of Spain and 9th countess of Montijo, title later ceded to her sister, married the 15th duke of Alba in 1849.Until her marriage in 1853, Eugénie variously used the titles of countess of Teba or countess of Montijo, but some family titles were inherited by her elder sister, through which they passed to the House of Alba.After the death of her father, Eugenia became the 9th countess of Teba, and is named as such in the "Almanach de Gotha" (1901 edition).
