Origin
Meaning and origin of Morros
The surname Morros originated in Spain during the medieval period. It is believed to have derived from the Spanish word "morro," which means a promontory or a rocky hill. This suggests that the name may have been initially given as a descriptive surname to someone who lived near or on a hill or rocky outcrop.
One of the earliest recorded instances of the name Morros can be found in the Cartulario de San Cugat del Vallés, a medieval cartulary from the monastery of Sant Cugat near Barcelona, dating back to the 11th century. This document mentions a certain "Petrus Morros" who was a landowner in the region.
In the 13th century, there are records of a noble family named Morros who owned lands and properties in the Catalonian region of Spain. One notable member was Bernat Morros, a knight who fought in the Reconquista against the Moors in the late 13th century.
During the 15th century, the name Morros appears in several historical documents from the Kingdom of Aragon, including records of merchants and traders who operated in the Mediterranean region. One such individual was Joan Morros, a wealthy merchant from Valencia who lived between 1420 and 1489.
In the 16th century, the Morros family established themselves in the Spanish colonies of the Americas. One notable figure was Pedro Morros, a Spanish explorer and conquistador who participated in the conquest of Guatemala in the early 1500s.
Another notable individual with the surname Morros was Miguel Morros y Tordillos, a Spanish military officer and engineer who lived from 1653 to 1711. He served as the Chief Engineer of the Spanish Army and was responsible for the fortifications of several cities across Spain.
Throughout the centuries, the surname Morros has been associated with various place names and locations in Spain, such as Morros de Rey in Catalonia, Morros Negros in Valencia, and Morros Blancos in Andalusia. These place names likely originated from the geographic features of the areas, further reinforcing the connection between the surname and rocky or hilly landscapes.

The bar chart below shows how Morros 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 Morros 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 Morros (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.
