Etymology
Cirillo is an Italian surname formed from the personal name Cirillo, the Italian form of Cyril/Cyrillic-type names. That personal name goes back through Latin and Greek to the Greek Kyrios, meaning “lord” or “master,” so the underlying sense is roughly “belonging to the Lord” or “of the Lord.” In surname use, it usually began as a patronymic name identifying someone as the son or family member of a man called Cirillo.
History
The surname is especially associated with southern Italy, where the given name Cirillo has long been in use through Christian naming traditions. It is related to the widespread veneration of saints named Cyril, which helped keep the personal name current. Like many Italian surnames, it later spread with migration to other parts of Europe and to the Americas.
