Sergi Surname in Italy

The Sergi surname originates from multiple lineages primarily found in southern Sardinia, the Strait area between Calabria (Reggio) and the province of Messina, as well as in the Salento area— especially in the provinces of Taranto, Brindisi, and Lecce— and in Rome. Related variants include Sergini, practically unique to Rome, and Sergio, more common in southern peninsular Italy. The surname traces back to the ancient Roman Sergia gens, a prominent patrician family noted in classical sources including Cicero in the 1st century BC, exemplified by Lucius Sergius Catilina. The surname’s historic importance is underscored by Pope Sergius I, who became pope in 687, reflecting the long-standing onomastic tradition.
