Origin
The surname Trijillo is of Spanish origin, derived from the place name Trujillo, which is a town located in the province of Cáceres, Extremadura, Spain. The name Trujillo is believed to have its roots in the Latin word "turris" meaning "tower" or "fortified place."
The earliest recorded instances of the Trijillo surname can be traced back to the 13th century in Spain. One notable historical figure bearing this surname was Juan Rodríguez de Trijillo, a Spanish explorer and conquistador who accompanied Hernán Cortés on his expedition to Mexico in the early 16th century.
Another prominent individual with the Trijillo surname was Diego de Trijillo, a Spanish conquistador who participated in the conquest of Peru alongside Francisco Pizarro in the 16th century. He is known for his role in the Battle of Cajamarca, where the Inca Empire's ruler, Atahualpa, was captured.
In the 17th century, a notable figure was Alonso de Trijillo y Carvajal, a Spanish lawyer and author who wrote extensively on legal topics and served as a judge in the Royal Chancery of Granada.
Moving to the 18th century, José Trijillo y Villavicencio was a Spanish military officer and colonial administrator who served as the governor of the Spanish colony of Florida from 1717 to 1718.
In the 19th century, Manuel Trijillo was a Mexican lawyer and politician who served as the Governor of the Mexican state of Chihuahua from 1852 to 1856.
It is worth noting that variations in the spelling of the surname, such as Trujillo or Truxillo, were common throughout history due to regional differences and the evolution of the Spanish language over time.

Among Census respondents with the surname Trijillo, the largest self-reported group is Hispanic at 85.0%. The next largest groups are White (7.1%) and American Indian/Alaska Native (4.4%).
The bar chart below shows how Trijillo 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 Trijillo surname at the time of the 2020 Census, not any inherent property of the name itself.
