The Abruzzo region, though geographically part of central Italy, is historically by tradition, culture, dialect and economy more related to Southern Italy. However, the most common patronymic surnames do not begin with the typical southern preposition "De", but with "Di", such as Di Francesco, Di Marco, Di Carlo, Di Giovanni.
Another feature among patronymic surnames in Abruzzo is the relevance of rare or almost "extinct" personal names, as Muzio, Amario, Ascenzo, Prinzio, Annunzio, Addario, Aloisio, Biase, Luzio, Censo, Iorio, Cola, Intino. Still another feature is the frequency of patronimics with the Latin plural ending "-is" and "-ibus", such as De Amicis, De Nuntiis, De Berardinis, De Leonibus, De Fidelibus.
The list of present surnames is mostly based on the white pages for the 1990's. For a number of places there are also listings derived from the 1742 census (the catasto onciario), and for southern Abruzzo from the Numerazione dei Fuochi of 1447.
