Origin
Meaning and origin of Lutrario
The surname Lutrario originated in Italy during the late medieval period. It is derived from the Latin word "lutra," which means otter. The name likely referred to someone who lived near a river or stream where otters were found, or perhaps someone who hunted or trapped otters.
Records from the 13th century in the town of Montepulciano, located in the Tuscan region of Italy, contain some of the earliest known references to the Lutrario name. The name is also found in historical documents from nearby towns such as Cortona and Castiglion Fiorentino during this time.
One of the earliest recorded individuals with the Lutrario surname was Giovanni Lutrario, a merchant who lived in Montepulciano in the late 1200s. Another notable figure was Matteo Lutrario, a landowner and winemaker from the same town, born around 1310.
In the 15th century, the Lutrario name appeared in records from the city of Florence, where a family of that name had established themselves as successful bankers and traders. One prominent member was Antonio Lutrario, a wealthy merchant and financier who lived from 1428 to 1492.
During the Renaissance, the Lutrario name was also associated with the arts. Pietro Lutrario, born in 1492 in Cortona, was a renowned painter and fresco artist who worked on commissions for churches and noble families throughout Tuscany.
In the 17th century, the Lutrario surname spread beyond Italy, with some members of the family emigrating to other parts of Europe. For example, Juan Lutrario, born in 1624 in Madrid, was a Spanish military officer who served in the Thirty Years' War.
As the centuries passed, the Lutrario name continued to be found in various regions of Italy, particularly in Tuscany and neighboring areas. However, by the 19th century, it had become relatively uncommon, likely due to changes in spelling or families dying out.
Demographics
Ancestry and ethnicity for Lutrario

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

Does the Census include every surname?

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
