Postiglioni Surname in Italy

The surname Postiglioni is primarily connected to the Lazio region, especially the provinces of Viterbo and Rome, but it is also found in Emilia-Romagna and Liguria. Its origin most likely stems from the occupation of the original bearers as postilions—drivers of stagecoaches or postal carriages. An alternative origin could be linked to the place name Postiglione, a municipality in the province of Salerno, or possibly from a Roman personal name that lacks historical documentation. Unlike the related and more widespread variant Postiglione, common in Campania, Apulia, and Lazio, Postiglioni remains a much rarer surname distinctive of the Lazio area.
