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.
English: from Middle English crouch, Old English crūc ‘cross’ (a word that was replaced in Middle English by the word cross, from Old Norse kross), applied either as a topographic name for someone who lived by a cross or possibly as a nickname for someone who had carried a cross in a pageant or procession.
