Origin
Meaning and origin of Lupercio
The surname Lupercio originates from Spain and can be traced back to the medieval period. It is derived from the Latin word "lupercus," which refers to a wolf or wolf-like creature. The name likely originated in regions where wolves were prevalent, and it may have been given to individuals who lived in areas known for their wolf populations.
One of the earliest recorded instances of the Lupercio surname can be found in the 13th-century manuscript "Codex Diplomaticus Regni Navarrae." This document mentions a nobleman named Alonso Lupercio, who was a vassal of the Kingdom of Navarre during the reign of King Sancho VII (1194-1234).
In the 15th century, a notable figure bearing the Lupercio surname was Juan Lupercio de Argensola, a Spanish poet and historian who lived from 1559 to 1613. He was born in Barbastro, Aragon, and is renowned for his work "Anales de Aragón," a historical account of the Kingdom of Aragon.
Another prominent individual with the Lupercio surname was Pedro Lupercio de Aragón, a Spanish military commander who participated in the Conquest of the Americas in the 16th century. He was born in Zaragoza, Aragon, around 1510 and served under Hernán Cortés during the conquest of Mexico.
Moving forward to the 17th century, we find Francisco Lupercio de Pando, a Spanish soldier and explorer who was born in Seville in 1612. He is credited with leading several expeditions into the interior of present-day Argentina and Chile, contributing to the exploration and mapping of those regions.
In the 18th century, a notable figure was Andrés Lupercio de Ávila, a Spanish merchant and philanthropist who lived from 1724 to 1798. He amassed a considerable fortune through his trading ventures and is remembered for his charitable contributions to the city of Cádiz, where he established several educational institutions and hospitals.
Throughout history, the surname Lupercio has been associated with various places, some of which may have influenced its geographical distribution. For example, the town of Luperciana in the province of Toledo, Spain, shares a similar root with the surname, suggesting a possible connection or influence.

The bar chart below shows how Lupercio 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 Lupercio 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.
