Pellegrino derives from the Latin peregrinus, meaning foreigner, wanderer, or traveller — the word that gives English its word "pilgrim." In medieval Italian, pellegrino meant primarily a pilgrim — someone undertaking a religious journey to a holy site — but the word also carried the sense of a stranger or foreigner, someone who had come from elsewhere.
As a surname, Pellegrino could have been applied in several ways: to a family that had made the pilgrimage to Rome, Santiago de Compostela, or Jerusalem; to a man who had come to a community as an outsider from another region; or more commonly as a devotional given name honouring Saint Pellegrino Laziosi — the fourteenth-century friar whose miraculous healing from cancer made him one of southern Italy's most venerated intercessors. The surname most often derives from this devotional baptismal tradition.
Pellegrino is most concentrated in Campania — the region around Naples, the great city that served as the cultural and commercial capital of southern Italy for centuries. The Campanian provinces of Naples, Salerno, Avellino, and Caserta all show strong Pellegrino representation in historical records. Naples was a major pilgrimage centre in its own right — the shrine of San Gennaro drew pilgrims from across the Mezzogiorno — and the name Pellegrino was deeply embedded in the city's Catholic naming culture.
The Campanian hinterland villages — particularly those in the hill country of Avellino and Salerno provinces — were among the most important sources of Italian-American emigration. Pellegrino families from these towns make up a substantial part of the Italian-American Pellegrino population today.
A significant secondary concentration of Pellegrino appears in Sicily, particularly in the western provinces of Palermo and Trapani. Monte Pellegrino — the mountain that rises above Palermo's bay — was one of the most sacred pilgrim destinations in southern Italy, the site of the shrine of Santa Rosalia, patron saint of Palermo. The mountain's name reflects the pilgrimage culture that surrounded it, and the Pellegrino families of Palermo may in some cases trace their name to ancestors associated with this site.
Calabria and Basilicata both show Pellegrino families in historical records. These regions, with their intense Catholic devotionalism and their tradition of saint veneration, were precisely the environment where names associated with pilgrimage and sainthood persisted longest. Calabrian and Basilicata emigrants carried the Pellegrino name to America and Argentina in the great emigration wave of 1880–1920.
Italy was the most important pilgrimage landscape in medieval Europe. Rome — the eternal city, the seat of the papacy, home to the tombs of Saints Peter and Paul — drew millions of pilgrims across the centuries. The Via Francigena, running from Canterbury through France and over the Alps to Rome, passed through northern Italy. For southern Italians, the journey to Rome was a defining act of religious life.
Beyond Rome, southern Italy had its own dense network of pilgrimage sites: Monte Sant'Angelo in Puglia, where the Archangel Michael appeared in a cave; the shrine of San Gennaro in Naples; Monte Vergine above Avellino; Pompei's miraculous Madonna. A man who made one of these journeys, or who came to a community as a stranger undertaking such a journey, might be identified by his community as the pellegrino — the pilgrim — and the name would stick.
Across the Mezzogiorno, names derived from religious concepts were among the most common sources of Italian surnames. Pellegrino, as both a devotional concept and the name of a specific saint, was widely used as a baptismal name. When Italian civil administration began requiring hereditary surnames — first under Napoleonic rule in the 1800s, then systematically after unification in 1865 — families whose father or grandfather had been named Pellegrino took that name as their hereditary surname.
The Pellegrino name dispersed through the great Italian emigration of 1880–1920. Campanian Pellegrinos settled predominantly in the north-eastern United States — New York, New Jersey, and the Connecticut industrial towns that absorbed large numbers of Campanian workers. Sicilian Pellegrinos followed similar routes, concentrated in New York City.
The Italian-American Pellegrino community is associated with several prominent figures in the arts, sciences, and public life. The name carries its pilgrimage history lightly in American usage — it has become simply a family name, but its medieval roots in the devotional culture of the Mezzogiorno give it a depth that rewards investigation.
Argentina received significant Pellegrino emigration as well. Carlos Pellegrini (1846–1906), president of Argentina from 1890 to 1892, was the son of a French-Italian immigrant — his name an Argentinisation of the Italian Pellegrini variant. The Argentine Pellegrini/Pellegrino community reflects the strong Italian presence in the River Plate region.
Pellegrini is the plural form of the name, used as a family name across northern and central Italy and found alongside Pellegrino in the south. American immigration records generally preserved the name fairly accurately, though Pellegrini and Pellegrino were sometimes interchanged. Researchers should search under both forms.
Tracing Pellegrino ancestry begins with identifying the specific Campanian or Sicilian comune of origin. Italian civil registration records from 1865 onward are increasingly available through the Antenati portal free of charge. Church registers predating civil registration often survive in provincial archives and are being progressively digitised.
For Sicilian Pellegrinos, Palermo provincial records are essential. For Campanian families, the provincial archives of Naples, Salerno, and Avellino hold the core records. The Antenati system covers most of these provinces.
