Perna is one of those Italian surnames that demonstrates the richness of the Latin language it inherits: the single Latin word perna designated both the cured leg of a pig (what we call ham) and the pen shell mussel — the Pinna nobilis — a large fan-shaped bivalve found in the warm shallows of the Mediterranean whose elongated form resembled a ham. Both meanings were in common use in Roman Latin, and both passed into Italian usage, giving the surname Perna an unusual dual potential for origin: it could indicate a butcher who cured hams, a person who fished or sold pen shell mussels, or someone nicknamed for the shape of their leg.
The physical nickname possibility should not be dismissed: Italian naming traditions were direct and uninhibited in using bodily characteristics as surname origins. A man who walked with a distinctive leg movement, who had an unusually shaped leg from injury or birth, or who was simply associated in village memory with legs — perhaps as a courier or messenger known for his walking ability — might reasonably acquire the surname Perna. The practical humor of Italian nickname-surnames was not always flattering, but it was always memorable.
The surname Perna is most strongly associated with Calabria — the toe of the Italian boot — where the pig-slaughtering and pork-curing traditions of the Calabrian mountains created a rich vocabulary of meat-related surnames. Calabria's isolation, its mountain economy, and its bitter winters historically made the annual pig slaughter (la mattanza del maiale) one of the most important events of the rural year: the pig fed the family through winter in the form of salami, nduja (Calabria's fiery spreadable sausage), soppressata, and cured hams. A family distinguished by excellence in curing hams — or perhaps owning the village's most prized pork products — might naturally acquire the surname Perna.
Alongside the inland Calabrian butchering tradition, the coastal communities of Calabria and Campania maintained the other meaning of perna: the pen shell mussel. The Pinna nobilis — now critically endangered — was historically harvested for its flesh (eaten) and its remarkable byssus (the fine, golden threads the mussel uses to anchor itself, historically woven into a silk-like fabric called sea silk). A family associated with pen shell harvesting on the Calabrian or Campanian coast might equally carry the Perna surname from this origin.
Perna families emigrated to the United States primarily from Calabria and Campania during the 1880–1920 period. The Calabrian emigration was particularly dramatic: Calabria was the most desperately poor region of Italy at the turn of the 20th century, its peasants facing crushing land rents, malaria, and total agricultural vulnerability. The earthquake of 1908 — which killed over 75,000 people in Reggio Calabria and Messina, Sicily in the most catastrophic natural disaster in European recorded history — accelerated emigration from the region and sent additional waves of Calabrian families across the Atlantic.
New York and New Jersey received the bulk of Calabrian emigrants, with concentrations in the Bronx, Brooklyn, and the Hudson County towns of New Jersey. Pennsylvania's mining regions drew additional Calabrian workers. The Perna surname appears in New York naturalization records and church registers from the Italian communities of the 1890s onward.
For Perna families, Calabria (especially Reggio Calabria and Catanzaro provinces) and Campania are the primary research territories. The Portale Antenati provides free access to civil registration records from 1866 for both regions. Calabrian records are generally well digitised. Passenger manifests from Ellis Island record the specific Italian comune of last residence.
Post-1908 earthquake records require special attention: many Reggio Calabria civil records were destroyed in the earthquake, and researchers may need to consult diocesan archives, surviving notarial records, and church records held at ecclesiastical archives to work around the gaps in the civil register. FamilySearch has microfilmed some Calabrian parish registers; the Archivio di Stato di Reggio Calabria holds the best collections of surviving civil and notarial documentation.
