Origin
Meaning and origin of Celorio
The surname Celorio has its origins in Spain, specifically in the region of Asturias, dating back to the medieval period. It is believed to be derived from the word "cellario," which referred to a monastic storehouse or cellar, suggesting that the name may have been associated with individuals responsible for managing the provisions of a monastery.
Celorio is also linked to the town of the same name located in the municipality of Llanes, Asturias. The town's name is thought to have been derived from the Latin word "cellarium," further reinforcing the connection between the surname and its potential monastic origins.
Historical records indicate that the name Celorio appeared in various medieval documents from Asturias, including the cartularies of monasteries and royal charters. One notable example is the mention of a certain Gonzalo Celorio in a legal dispute over land rights in the 13th century.
The earliest recorded individual bearing the surname Celorio is Juan Celorio, a scholar and clergyman who lived in the 15th century. He was known for his contributions to the field of canon law and served as a professor at the University of Salamanca.
Another prominent figure with the surname Celorio was Alonso Celorio, a Spanish conquistador who participated in the conquest of Mexico alongside Hernán Cortés in the early 16th century. He played a crucial role in several battles against the Aztecs and later served as a colonial administrator in New Spain.
In the 17th century, Pedro Celorio y Campomanes (1580-1645) was a notable jurist and legal scholar from Asturias. He held influential positions in the Spanish court and authored several treatises on legal matters, contributing significantly to the development of Spanish jurisprudence.
The surname Celorio also has connections to the aristocracy, with the Marquises of Celada y Celorio being a prominent noble family from Asturias. One of their ancestors, Álvaro Celorio y Cañedo (1705-1790), was a distinguished military officer who served in various campaigns during the War of the Spanish Succession.
Another noteworthy figure was María Celorio y Mendoza (1790-1865), a Spanish writer and poet who gained recognition for her literary works, including poetry collections and historical novels set in her native Asturias.
While the surname Celorio has its roots in Asturias, over time, it has spread to other regions of Spain and even to Latin American countries due to migration and colonization. However, its origins can be traced back to the medieval period in northern Spain, with a strong connection to monastic life and the management of provisions.

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