On the title Duke of Uceda

Duchess Isabel María de Sandoval y Girón used for this name a practice used by women of the High Spanish Nobility and the ecclesiastic officers from such families since the middle of the 14th century, namely, that her mother was the 3rd proprietary Duchess of Uceda, a Grandee of Spain and describing herself as Feliche de Sandoval Ursino, or Feliche de Sandoval Orsini, while her father was, jure uxoris, and since marrying her in 1645 3rd Duke Consort of Uceda, albeit being known also as Gaspar Téllez-Girón y Sandoval, 5th Duke of Osuna,.
In other words, the 3rd and the 4th Ducal titles associated to the Dukedom of Uceda were held in property by two women, Feliche de Sandoval and Isabel Maria de Sandoval, while their fathers/husbands however, were respectively named "Alvarez de Toledo",, "Pacheco Téllez-Girón", and "Tellez-Giron y Sandoval",.
It is through this elaborate but by no means at the time uncommon, "family names engineering" that it was possible to pass on the family name "Sandoval" from Francisco Gómez de Sandoval, 1st Duke of Lerma,.
