Anthony Madrid

(male) The usual English form of the old Roman family name Antonius, which is of uncertain (probably Etruscan) origin. The spelling with -th- (not normally reflected in the pronunciation) represents a learned but erroneous attempt to associate it with Greek anthos ‘flower’. In the post-classical period it was a common name, borne by various early saints, most notably a 3rd-century Egyptian hermit monk, who is regarded as the founder of Christian monasticism.

Spanish: habitational name from what is now Spain's principal city. Throughout the Middle Ages it was of only modest size and importance, and did not become the capital of Spain until 1561. Its name is of uncertain origin, most probably a derivative of Late Latin matrix, genitive matricis ‘riverbed’, much changed by Arabic mediation. Compare Madrigal. There are other, smaller places of the same name in the provinces of Burgos and Santander, and these may also be sources of the surname.
