D'Agostino is a patronymic surname — it means "of Agostino," indicating that the first person to bear the surname as a family name was the son (or descendant) of a man called Agostino. In Italian surname formation, the particle d' (a contraction of di) placed before a personal name creates this patronymic form: D'Antonio means "of Antonio," D'Angelo means "of Angelo," and D'Agostino means "of Agostino."
The given name Agostino is the Italian form of Augustine — from the Latin Augustinus, itself a diminutive of Augustus. The name entered Christian usage primarily through Saint Augustine of Hippo (354–430 AD), whose extraordinary influence on Western theology made his name one of the most widely used in the Catholic baptismal tradition. Naming children Agostino — particularly those born on or near his feast day of August 28th — was common across Catholic southern Italy, and those families in which the name Agostino was prominent across a generation might adopt it as their identifying characteristic.
The surname D'Agostino is concentrated in the southern Italian regions — Campania, Basilicata, Calabria, and Sicily — which were the source of the largest waves of Italian emigration to the United States between 1880 and 1924. Its distribution reflects both the prevalence of the given name Agostino in the south and the general pattern by which patronymic surnames formed more readily in communities where family identity was closely tied to the patrilineal line.
Saint Augustine of Hippo (354–430 AD) is one of the most consequential figures in the history of Western civilization. Born in Thagaste in Roman North Africa (modern-day Algeria) to a pagan father and a devout Christian mother (Monica, later canonised), he was educated in Carthage and Rome, lived through a period of Manichean belief and philosophical inquiry, and converted definitively to Christianity in Milan in 386. He was baptised by Saint Ambrose, returned to Africa, became Bishop of Hippo Regius, and spent the rest of his life writing, teaching, and governing his diocese.
His two great works — the Confessions (c.400 AD) and The City of God (413–426 AD) — shaped Catholic theology and Western philosophy for fifteen centuries. The Confessions is the first autobiography in the Western tradition: a sustained reflection on his own spiritual journey, addressed to God, that invented the genre of introspective personal narrative. The City of God, written in response to the sack of Rome by the Visigoths in 410, developed the theological framework of two cities — the earthly city of human politics and the heavenly city of God — that defined medieval Catholic political thought.
Augustine's influence extended to the Protestant Reformation — Luther and Calvin drew heavily on his theology of grace and predestination — making him perhaps the only Church Father whose ideas shaped both Catholic and Protestant Christianity. His feast day on August 28th made August one of the months when Agostino was most commonly given as a baptismal name in Catholic communities, and the D'Agostino families of southern Italy carry in their name a connection to one of the foundational figures of Western intellectual history.
Campania — the region around Naples — is the primary concentration zone for D'Agostino families. Naples itself and the surrounding countryside, the Salerno coast, and the Irpinia interior of the province all show significant D'Agostino populations in the nineteenth-century records. Campania was one of the most densely populated and economically stressed regions of Italy in the emigration era — the combination of a huge peasant population, inadequate land, and a semi-feudal agricultural system drove millions of Campanians to emigrate, particularly to New York and the cities of the northeastern United States.
Basilicata — the poor, mountainous region between Campania and Calabria — is the second significant concentration zone. Basilicata (or Lucania, as it was historically known) sent a large proportion of its population to America in the emigration decades: Carlo Levi's Christ Stopped at Eboli (1945), the memoir of his time in internal exile in Basilicata in the 1930s, documented the extreme poverty and isolation of the region's peasant communities. D'Agostino families from Basilicata are among the less-documented branches of the name, reflecting the relative scarcity of records from this underdeveloped region.
The D'Agostino name arrived in the United States primarily with the great southern Italian emigration of the 1880s to 1920s. New York City and the surrounding metropolitan area received the heaviest concentration of Campanian and southern Italian emigrants, and D'Agostino families are well-represented in the Italian-American communities of the five boroughs, New Jersey, and Connecticut.
The most prominent American manifestation of the name is the D'Agostino supermarket chain — the family grocery business founded by Nicola D'Agostino in New York City in 1932. The D'Agostinos established their first store in Harlem and expanded through the postwar decades into a chain of Manhattan and Westchester stores that became a familiar presence in the city's grocery landscape. At its peak, D'Agostino's operated nearly thirty stores in the New York metropolitan area; the chain contracted through the 1990s and 2000s as supermarket competition intensified, but the name remains identified in New York with the Italian-American grocery tradition that the D'Agostino family helped define.
Campania and Basilicata are the primary research territories. Identifying the specific commune — through family documents, ship manifests, or naturalization papers — is essential before searching Italian records.
