Mercedes is one of the few names attached to luxury living that we can wholeheartedly recommend, it being a legitimate Spanish appellation stemming from one of the epithets given to the Virgin Mary--Santa Maria de las Mercedes, or Our Lady of the Mercies. The car, by the way was named after the eleven-year-old daughter of the Daimler company's French distributor in 1901.
 Always well used in the Spanish-speaking community, Mercedes had a sudden spurt of overall popularity in the 1990's, moving as high as Number 164 in 1991.
 Mercedes has been widely used in a variety of art forms--from the opera Carmen to Dumas' The Count of Monte Cristo to the film Pan's Labyrinth to the TV show Glee.
