The form Trojani is quite rare, with a minor presence in Rome. The surname likely originates from the ethnonym linked to the town of Troia in Foggia province, although it may also derive from the medieval personal name Troianus, documented among members of the University of Perugia in the 16th century, indicating an early use as a given name that eventually evolved into a surname.
