Origin
Meaning and origin of Laudisio
The surname LAUDISIO has its roots in Italy, originating in the medieval period around the 12th century. The name is believed to be derived from the Latin phrase "laus diis," which translates to "praise to the gods." This suggests that the name may have been initially bestowed upon someone who was deeply religious or associated with the church.
During the Renaissance era, the name LAUDISIO began appearing in various historical records and manuscripts across Italy, particularly in the regions of Campania and Basilicata. One notable early record is a land deed from the year 1412, which mentions a certain Giovanni LAUDISIO as the owner of a vineyard in the town of Avellino.
In the 16th century, the LAUDISIO name gained prominence with the birth of Francesco LAUDISIO (1525-1598), a renowned scholar and theologian from Naples. Francesco's writings on theological subjects were widely circulated throughout Europe and earned him a reputation as a leading intellectual of his time.
Another prominent figure bearing the LAUDISIO name was Antonio LAUDISIO (1640-1711), a skilled architect and engineer who was responsible for the design and construction of several notable buildings in the city of Potenza, including the Church of San Francesco and the Palazzo Marchesale.
The 18th century saw the emergence of Vincenzo LAUDISIO (1732-1804), a celebrated painter from the town of Matera. Vincenzo's works, which often depicted religious scenes and landscapes, were highly sought after by wealthy patrons throughout Italy and beyond.
In the 19th century, the LAUDISIO name gained further recognition with the birth of Giuseppe LAUDISIO (1815-1892), a prominent political figure and advocate for Italian unification. Giuseppe played a key role in the Risorgimento movement and was instrumental in the creation of the modern Italian state.
Throughout its history, the surname LAUDISIO has been associated with various place names and older spellings, such as Laudizio, Laudizzo, and Laudisi. While the name has maintained a strong presence in southern Italy, it has also spread to other parts of the country and even beyond Italy's borders due to migration and immigration.

The bar chart below shows how Laudisio 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 Laudisio surname at the time of the 2020 Census, not any inherent property of the name itself.
