Origin
The surname LARIVA originated in Italy during the medieval period, specifically in the regions of Lombardy and Piedmont. It is believed to be derived from the Italian word "riva," which means "riverbank" or "shore," suggesting that the earliest bearers of this name lived near a river or a body of water.
One of the earliest recorded instances of the name LARIVA can be found in the Codice Diplomatico della Lombardia Medievale, a collection of medieval documents from the 11th century. In this collection, a certain "Guglielmo de Lariva" is mentioned as a landowner in the city of Pavia.
During the 13th century, the name LARIVA appeared in several historical records from the town of Novara, located in the Piedmont region. A notable figure from this era was Giacomo LARIVA, a wealthy merchant and landowner born in 1245 and died in 1312.
In the 15th century, the name LARIVA gained prominence in the city of Milan. One of the most famous bearers of this name was Antonio LARIVA, a renowned architect and sculptor who lived from 1420 to 1498. He was responsible for designing several churches and palaces in Milan and its surrounding areas.
Another notable figure was Giambattista LARIVA, a philosopher and writer born in Genoa in 1560. He authored several treatises on ethics and political philosophy, and his works were widely read throughout Europe during the Renaissance period. Giambattista LARIVA died in 1621.
The name LARIVA also has connections to the city of Venice, where a family with this surname held significant influence in the 16th and 17th centuries. Pietro LARIVA (1538-1612) was a prominent Venetian lawyer and statesman who served as a member of the Council of Ten, one of the most powerful governing bodies in the Venetian Republic.
In the 18th century, the LARIVA name appeared in the records of the Duchy of Parma, where a branch of the family had settled. Lucrezia LARIVA (1724-1789) was a highly respected painter known for her portraits of aristocrats and members of the Farnese ducal court.
During the 19th century, Giuseppe LARIVA (1812-1887) was a renowned Italian composer and conductor who gained fame for his operas and orchestral works. He was born in Turin and spent most of his career in Milan, where he served as the director of the prestigious Teatro alla Scala.
Demographics
Among Census respondents with the surname Lariva, the largest self-reported group is Hispanic at 90.7%. The next largest groups are White (5.9%) and Black (1.7%).
The bar chart below shows how Lariva bearers described their own race and ethnicity on the 2020 Census form. 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 Lariva surname at the time of the 2020 Census, not any inherent property of the name itself.
