De Lorenzo is an Italian surname meaning "son of Lorenzo". It belongs to a common pattern of Italian patronymic surnames formed with the preposition de (“of”), indicating descent or affiliation. The name Lorenzo itself is the Italian and Spanish form of the Latin name Laurentius, which derives from the Roman cognomen Laurentius, meaning “from Laurentum” – a city in ancient Italy whose name likely comes from Latin laurus (“laurel”). Etymology The root name Laurence (Latin Laurentius) gained widespread popularity due to Saint Laurence, a 3rd-century deacon and martyr from Rome who, according to tradition, was roasted alive on a gridiron after presenting the poor as the church's treasures. The name spread throughout Christian Europe, and in Italy it evolved into Lorenzo. Surnames like De Lorenzo arose to identify individuals as “descendant of Lorenzo,” following a typical Italian onomastic pattern.
