Origin
Meaning and origin of Tenorio
The surname Tenorio originated in Spain and Portugal during the medieval period. It is derived from the Spanish word "tenorio," which means "landowner" or "lord of the manor." The name likely has its roots in the Latin word "tenet," meaning "to hold" or "to possess."
The earliest recorded instances of the Tenorio surname can be traced back to the 13th century in various regions of the Iberian Peninsula, including Castile, Aragon, and Galicia. Some historical records mention individuals with variations of the name, such as Tenorio, Tenorio de Avila, and Tenorio de Castilla.
One of the most notable historical figures bearing the Tenorio name was Don Juan Tenorio, a legendary Spanish nobleman and seducer who lived in the 14th century. His exploits and adventures were immortalized in the famous play "El Burlador de Sevilla y Convidado de Piedra" (The Trickster of Seville and the Stone Guest) by Tirso de Molina, which later inspired other works like Mozart's opera "Don Giovanni."
Another prominent figure with the Tenorio surname was Álvaro Tenorio, a Spanish military leader and admiral who served under King Alfonso XI of Castile in the 14th century. He played a crucial role in the Battle of Salado against the Marinid dynasty of Morocco in 1340.
In the 15th century, Pedro Tenorio was a Spanish Catholic prelate who served as the Archbishop of Toledo from 1377 to 1399. He was a significant figure in the ecclesiastical and political spheres of his time.
During the 16th century, Pedro Tenorio de Guzmán was a Spanish conquistador who participated in the conquest of Peru alongside Francisco Pizarro. He played a role in the capture of the Inca emperor Atahualpa and the subsequent subjugation of the Inca Empire.
The Tenorio surname also has a presence in Portuguese history. One notable figure was João Tenório, a 15th-century Portuguese navigator and explorer who participated in the early voyages of exploration along the West African coast under the sponsorship of Prince Henry the Navigator.
While the Tenorio surname has its roots in the Iberian Peninsula, it has since spread to other parts of the world, particularly to Latin American countries due to Spanish and Portuguese colonization and migration.

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

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Tenorio (2000, 2010, 2020).
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.
Why don't the ancestry percentages always add up to exactly 100%?
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
