Origin
Meaning and origin of Sudario
The surname SUDARIO has its origins in Spain, where it first appeared in the late 15th century. It is derived from the Spanish word "sudario", which means "shroud" or "winding sheet". This word is itself derived from the Latin word "sudarium", which means the same thing.
The name SUDARIO is thought to have been an occupational surname, given to someone who made or sold shrouds or winding sheets for use in burials. It may also have been a descriptive surname, referring to someone who wore or carried a shroud for some reason, perhaps as part of a religious ritual or procession.
One of the earliest recorded instances of the name SUDARIO comes from the town of Seville, in the southern Spanish region of Andalusia. In a legal document dated 1492, a man named Juan SUDARIO is mentioned as a witness to a property transaction.
Another early reference to the name can be found in the records of the Spanish Inquisition, which were kept meticulously throughout the 15th and 16th centuries. In 1522, a woman named Maria SUDARIO was brought before the Inquisition in the city of Toledo, accused of practicing Jewish rituals in secret.
Over the centuries, the name SUDARIO has been spelled in various ways, including SUDARO, SUDARO, and SUDERO. These variations likely reflect regional differences in pronunciation and spelling conventions.
One notable bearer of the name SUDARIO was Pedro SUDARIO, a Spanish explorer and navigator who was part of the expedition led by Juan Ponce de León in 1513. Pedro SUDARIO is credited with being one of the first Europeans to set foot on what is now the state of Florida.
Another famous SUDARIO was Juana SUDARIO (1568-1624), a Spanish poet and playwright who was part of the literary circle around Miguel de Cervantes. Her work was widely acclaimed during her lifetime, but has since fallen into relative obscurity.
In the 18th century, there was a family of Spanish nobility with the name SUDARIO. The most prominent member of this family was Rodrigo SUDARIO (1712-1786), who served as the governor of Puerto Rico from 1760 to 1765.
As the Spanish Empire expanded across the Americas, the name SUDARIO spread to many of the colonies. One of the earliest recorded instances of the name in the New World comes from Mexico, where a man named Gonzalo SUDARIO was listed as a resident of the town of Veracruz in 1576.
Another notable bearer of the name was María SUDARIO (1845-1917), a Cuban-born writer and activist who was a vocal supporter of Cuban independence from Spain. She published several novels and collections of poetry that celebrated Cuban culture and identity.

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 Sudario surname at the time of the 2020 Census, not any inherent property of the name itself.

Does the Census include every surname?
No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.

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