Origin
Meaning and origin of Solorio
The surname Solorio originates from Spain, specifically the Castilian region. It dates back to the medieval period, around the 12th century. The name is believed to be derived from the Latin word "solarius," meaning "sun-related" or "relating to the sun."
This surname likely originated as a descriptive name, referring to someone who lived in a sunny or well-lit area, or perhaps someone with a sunny disposition. It could also have been an occupational name for someone who worked in a sunny location or with sun-related tasks, such as a tanner or vintner.
One of the earliest recorded instances of the Solorio surname appears in the 13th century, in the "Tumbo Negro" (Black Book) of Santiago de Compostela, a medieval manuscript that recorded land grants and donations to the cathedral. This document mentions a certain "Martinus Solorio" from the village of Sobrado.
In the 14th century, the Solorio name appeared in various records and documents from the Castilian region, including the "Becerro de las Behetrias" (Book of Fiefdoms), which cataloged the feudal holdings and vassals of the Crown of Castile.
Notable individuals with the Solorio surname include Juan Solorio (c. 1470-1548), a Spanish explorer and conquistador who participated in the conquest of Mexico alongside Hernán Cortés. Another prominent figure was Diego Solorio (c. 1520-1589), a Spanish jurist and author who served as a magistrate in the Audiencia of Mexico.
In the 16th century, the Solorio family established itself in the region of Extremadura, where they held estates and positions of prominence. One member of this branch was Pedro Solorio y Quiñones (1549-1625), a Spanish military commander who served as the governor of Cartagena de Indias (present-day Colombia).
Another notable Solorio was Juan Solorio de Quiñones (1603-1677), a Spanish nobleman and politician who served as the Viceroy of Sardinia and the Governor of the Duchy of Milan in the mid-17th century.
Over time, the Solorio surname spread beyond Spain, carried by explorers, colonists, and immigrants to various parts of the Americas, particularly Mexico and other Spanish-speaking regions.

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 Solorio 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.
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.
