Origin notes
Origin and meaning
The surname De Rosa is widespread across peninsular Italy, especially concentrated in Southern Italy and notably in Campania. The name originated from the medieval personal name Rosa, used both as a good luck name and later as a sign of devotion to the namesake saint. De Rosa literally means “the children or descendants of Rosa.” Historical evidence dates back to medieval times, including a 1177 document from the Lombardy Diplomatic Code mentioning 'Ambrosio de Rosa'. The related surname Di Rosa shares the root but has distinct local origins and concentrations, particularly in the Marche, Abruzzo, Molise, Campania, and predominantly in Sicily.
