The evolution of the title since the middle of the XVII Century

Mauro Alvaro, the eldest male, was 3rd Marquis, marrying on 22 October 1627, Genoese noble woman Maria Francesca Doria, a daughter of Carlo I Doria del Carretto, 1st Duke of Tursi, a Grandee of Spain with many other lesser titles, (Genoa, Italy, 15 October 1576 – Genoa, Italy, 19 December 1649) and Placidia Spinola, (1584–1660), 2nd Marchioness of Calice and Veppo, between other titles. No surviving adult issue.

The 4th Marchioness, was the eldest sister of the 2nd Marquis Alvaro II, named Maria Eugenia de Bazán y Benavides. She was married in 1620 to Jerónimo Pimentel, Marquis of Bayona, Viceroy of Sardinia, 1626–1631, deceased 15 April 1631, with issue. He was the 8th son of Juan Alfonso Pimentel de Herrera, 5rh Duke of Benavente, deceased 7 November 1621, Viceroy of Valencia, 1598–1602, Viceroy of Naples, 1603–1610. The other male of the family, Fernando, became Chancellor, Rector, of the University of Salamanca, and later, after ecclesiastical jobs at Seville and Cordoba, Archbishop of Palermo, Sicily, Italy .
Thus, the title of Marquis of Bazán became attached to a branch of the Pimentel family, a female called Mencia Pimentel y Bazan.When she married a "Benavides" male, it was agreed by the couple that if they had a male, the male child would be named Francisco Diego de Bazan y Benavides to honor her ancestors and "recuperate" her ancestors name, something not uncommon between the High Spanish Nobility.
In fact, a son was born and named Francisco de Bazan y Benavides (died in 1680). He was Captain General of the Spanish galleys and Viceroy of Sicily, (1674 Interim), using always his mother's ancestors' family name, "Bazán", as a token of respect, and possibly, duty.
