Spanish: from Maria de los Dolores ‘Mary of the Sorrows’, a reference to the Seven Sorrows of the Virgin Mary. The feast of Our Lady's Dolours was established in 1423. The name is now also borne in the English-speaking world, mainly by Roman Catholics. In part, it was popularized by the film star Dolores Del Rio (1905–83), born in Mexico as Dolores Asunsolo.
Spanish (Hernández) and Jewish (Sephardic): patronymic from the personal name Hernando (see Fernando). This surname also became established in southern Italy, mainly in Naples and Palermo, since the period of Spanish dominance there, and as a result of the expulsion of the Jews from Spain and Portugal at the end of the 15th century, many of whom moved to Italy.
