Marquess of San Isidro
Marquess of San Isidro () was a hereditary title in the Peerage of Spain, granted in 1730 by Philip V to Pablo Rui-Gómez, Viscount of Benafarces, knight of the Order of Santiago and perpetual "regidor" of León. The title was granted in recognition of his contribution to the restoration of the Basilica of San Isidoro in Leon, Spain. The baroque palace of the Marquesses of San Isidro was, before a heavy fire in 1942, located at an emblematic spot where the Spanish troops first rebelled against Napoleon in León. There is also an avenue in the  same city, named after the third Marquess of San Isidro, Santos Rui-Gómez, who perished in battle fighting for Spain's independence from the French in 1813. As of 2010, the title is extinct, as more than 40 years have elapsed since the death of the last holder (1885).
