Origin
Meaning and origin of Zamarron
The surname Zamarron has its origins in the Iberian Peninsula, specifically in Spain. It likely emerged during the Middle Ages, around the 10th to 12th centuries. The name is derived from the Spanish word "zamarro," which refers to a type of sheepskin jacket or coat worn by shepherds and peasants in the mountainous regions of northern Spain.
One of the earliest recorded instances of the Zamarron surname can be traced back to the province of Asturias, located in the northern part of Spain. This region was known for its rugged terrain and strong pastoral traditions, where shepherding was a common occupation. It is believed that the Zamarron name originated from a particular family or individual involved in the production or trade of these sheepskin garments.
In the 13th century, a document known as the "Libro Becerro de las Behetrías de Castilla" (Book of Beekeeper's Rights in Castile) mentions several individuals with the surname Zamarron, indicating their presence in the region during that time period. This document served as a record of land ownership and rights in the Kingdom of Castile.
Throughout history, several notable individuals have borne the Zamarron surname. One such person was Juan Zamarron, a Spanish conquistador who participated in the conquest of Mexico in the 16th century under the command of Hernán Cortés. Another notable figure was Pedro Zamarron, a 17th-century Spanish painter known for his religious works and portraits.
In the 18th century, a prominent Zamarron family resided in the town of Cabezón de la Sal, located in the region of Cantabria. This family was involved in the local governance and administration of the town. One of its members, Francisco Zamarron, served as the mayor of Cabezón de la Sal in the late 1700s.
Another notable individual was Ignacio Zamarron, a 19th-century Spanish military officer who fought in the Peninsular War against the French forces of Napoleon. He was born in 1785 and played a significant role in the defense of Spain during this conflict.
Over time, the Zamarron surname has spread to other parts of Spain and even to Spanish-speaking countries in Latin America. However, its origins can be traced back to the rugged and pastoral landscapes of northern Spain, where the name was likely borne by families involved in the production or trade of traditional sheepskin garments.

The bar chart below shows how Zamarron 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 Zamarron 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 Zamarron (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.
