Durans (enduring, or lasting) formed the name which no reader of Don Quixote can forget as that of the enduring hero, lying on his back on the marble tomb, in the cave of Montesinos, who uttered that admirable sentiment, "Patience, cousin, and shuffle the cars!" 
... Durandus is the Latinized surname of the great French lawyer of the middle ages; and Durandus again is familiar to the lover of mediaeval symbolism; but none of these can approach in honour the great Florentine Durante Alighieri... (History of Christian Names, Yonge, 1884).
