Meaning and origin of Cousino
The surname Cousino traces its roots back to the Iberian Peninsula, specifically the regions of Portugal and Spain, during the Middle Ages. It is believed to have originated as a locational or topographic name, referring to a person who lived near or came from a place called "Cousino" or a similar-sounding name.
This surname is thought to be derived from the Latin word "cusinus," which means "cousin" or "relative." It's possible that the name was initially bestowed upon someone who lived near or in a place associated with their relatives or extended family members.
One of the earliest recorded instances of the Cousino surname can be found in the Inquisition records of the 15th century in Portugal, where several individuals with this name were mentioned. In Spain, the surname appears in various historical documents from the 16th century onwards, particularly in regions like Andalusia and Castile.
During the Age of Exploration, some individuals bearing the Cousino surname may have accompanied Spanish and Portuguese explorers and settlers on voyages to the Americas, contributing to the spread of this name across the globe.
Notable individuals with the Cousino surname throughout history include:
1. Pedro Cousino (c. 1530-1598), a Spanish soldier and explorer who participated in the conquest of Chile under Pedro de Valdivia.
2. María Cousino (c. 1620-1685), a Portuguese woman accused of witchcraft during the Inquisition trials in Lisbon.
3. Juan Cousino (1745-1823), a Spanish-born engineer who contributed to the development of irrigation systems in colonial Mexico.
4. Catalina Cousino (1805-1878), a Chilean landowner and philanthropist known for her support of educational institutions in Santiago.
5. Tomás Cousino (1875-1942), a prominent Chilean businessman and industrialist who founded the Cousino Group, a conglomerate of companies involved in mining, agriculture, and manufacturing.

The bar chart below shows how Cousino 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 Cousino 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 Cousino (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.
