Origin
Meaning and origin of Reinoso
The surname Reinoso originated in Spain during the medieval period. It is derived from the Spanish word "reina," meaning "queen," and the suffix "-oso," which denotes an abundance or an association with something. The name likely referred to someone who lived near the residence of a queen or worked in service to a royal household.
Reinoso is a locational surname, meaning it was originally used to identify someone from a specific place. One of the earliest recorded instances of the name comes from the town of Reinoso in the province of Burgos, located in the northern part of Spain. This town's name can be traced back to the Latin word "regina," also meaning "queen."
In the 12th century, the name Reinoso appeared in the Cartulario de San Millán de la Cogolla, a collection of medieval documents from the Monastery of San Millán de la Cogolla in La Rioja, Spain. This suggests that the name was already well-established in the region at that time.
One of the earliest notable individuals with the surname Reinoso was Juan Reinoso, a Spanish poet and soldier who lived in the 15th century. He served under King Ferdinand II of Aragon and wrote several poems celebrating the military victories of the Spanish monarchs.
Another prominent figure was Fernán Reinoso, a Spanish explorer and conquistador who accompanied Francisco Pizarro on his expeditions to Peru in the 16th century. He played a significant role in the conquest of the Inca Empire and was later granted encomiendas (land grants) in recognition of his services.
In the 17th century, Martín Reinoso y Mendoza was a Spanish painter known for his religious works, particularly those commissioned by churches and monasteries in Madrid and Andalusia. His paintings can still be found in various Spanish museums and art collections.
Francisco Reinoso y Muñoz de Velasco, born in 1734, was a Spanish military officer and colonial administrator who served as the Governor of Panama from 1781 to 1789. He oversaw the construction of several important fortifications and infrastructure projects during his tenure.
In the 19th century, José Reinoso Trueco was a Chilean lawyer, politician, and diplomat who served as the Minister of Foreign Affairs and briefly as the interim President of Chile in 1829. He played a crucial role in shaping the country's foreign policy during its early years as an independent nation.

The bar chart below shows how Reinoso 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 Reinoso 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 Reinoso (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.
