In this case, the surname was created from Marco, which comes from the from Latin Marcus. As the Italian "di" means "of," we may interpret the surname as meaning "son or descendant of Marco."

Early Origins of the Demarco family

The surname Demarco was first found in Messina (Sicilian: Missina; Latin: Messana), capital of the province of Messina, where a family of this have long been found. The city of Messina was founded by the Greeks in the 8th century B.C., was a free city allied with Rome, and over the centuries was taken successively by the Goths, Byzantines, Arabs, Normans, Spaniards, and finally (in 1860) by Garibaldi and the Italians. In ancient times only persons of rank, the podesta, clergy, city officials, army officers, artists, landowners were entered into the records. To be recorded at this time, at the beginning of recorded history, was of itself a great distinction and indicative of noble ancestry. The family of this name in Sicily are said to have come from Spain sometime before the 13th century and were conjecturally descended from a 3rd century Pope Marcellus who resided in Paris.
