Origin
Meaning and origin of Delandro
The surname DELANDRO originated in Italy during the medieval period. It is believed to be derived from the Italian word "delandro," which means "of the laurel tree." This suggests that the name may have originated as a locational surname, referring to someone who lived near or worked with laurel trees.
One of the earliest recorded instances of the DELANDRO surname can be found in the Codice Diplomatico Longobardo, a collection of medieval documents from the Lombard region of Italy dating back to the 8th century. In this collection, there is a reference to a landowner named "Petrus de Landro" in the year 792.
The DELANDRO name also appears in the Libro Rosso, a historical record from the city of Pisa in Tuscany. This document, dating from the 12th century, mentions a nobleman named "Guido Delandro" who held significant political power in the region.
During the Renaissance period, the DELANDRO name gained some prominence in the arts. A notable figure was Giovanni Delandro, a Venetian painter born in 1490, who was known for his religious works and portraits of prominent figures in Venice.
In the 17th century, the DELANDRO family produced a respected scholar and philosopher named Niccolò Delandro. Born in 1623 in Naples, Niccolò wrote extensively on topics such as metaphysics and ethics, and his works were widely read throughout Europe during his lifetime.
Another notable bearer of the DELANDRO name was Francesca Delandro, a celebrated opera singer from Milan. Born in 1785, she performed at various opera houses across Italy and was particularly renowned for her roles in the works of Rossini and Bellini.
The DELANDRO surname has also been associated with several place names in Italy over the centuries. For example, the village of Delandro in the province of Bergamo was likely named after an early bearer of the surname who lived or owned land in the area.

The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
Percentages are shown for every Census year so the breakdown stays comparable over time. When the source file also includes raw headcounts, Name Census shows those alongside the percentages in the legend.
Keep in mind that these are self-reported numbers. A person's surname does not determine their race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the Delandro surname at the time of the 2020 Census, not any inherent property of the name itself.
