Its source is a Spanish expression meaning "Mercies."
The name Mercedez ranked 3546th in popularity for females of all ages in a sample of the 1990 US Census.
Though this name appears on the 1990 U.S. Census lists, it is used by only a small percentage of the general population.
This name derives from one of the Roman Catholic titles for the Virgin Mary, Maria de las Mercedes (''Mary of the Mercies''). However, the name's modern association with an upscale German automobile may have more to do with its continuing popularity.
