Origin
The surname Sotomayor originated in Spain, tracing its roots back to the 12th century. It is derived from the Galician phrase "soto o mayor," which means "the larger grove or thicket." This suggests that the name may have originated as a toponymic surname, referring to a particular place or region known for its larger groves or wooded areas.
The earliest recorded instances of the name Sotomayor can be found in medieval Spanish documents and records. One notable example is the appearance of the name in the "Libro de las Behetrías de Castilla," a 14th-century manuscript that documented the land ownership and tax obligations of various regions in Castile.
During the 15th century, the Sotomayor family gained prominence in Spain, particularly in the regions of Galicia and Castile. Juan Sotomayor y Figueroa (1450-1516), a Spanish nobleman and military leader, played a significant role in the conquest of Granada and was later appointed as the first governor of Cuba by King Ferdinand II of Aragon.
In the 16th century, the Sotomayor family expanded its influence to the Americas through the Spanish colonization efforts. Álvaro de Sotomayor y Valmediano (1525-1593), a Spanish conquistador and explorer, was one of the founders of the city of Copiapó in present-day Chile.
Another notable figure with the surname Sotomayor was Gaspar de Sotomayor y Silva (1584-1648), a Spanish military commander and viceroy of New Spain (present-day Mexico) from 1642 to 1648. He played a crucial role in defending the territory against internal unrest and external threats during his tenure.
In the 18th century, José Sotomayor y Terrazas (1703-1768) was a prominent Spanish military officer and governor of Havana, Cuba, from 1761 to 1768. He oversaw the reconstruction efforts in Havana after the city was captured by the British during the Seven Years' War.
The surname Sotomayor has also been associated with various place names and historical locations throughout Spain and Latin America. For example, the town of Sotomayor in Galicia, Spain, and the Sotomayor Municipality in the state of Hidalgo, Mexico, are named after individuals or families bearing this surname.
Demographics
Among Census respondents with the surname Sotomayor, the largest self-reported group is Hispanic at 89.4%. The next largest groups are White (8.4%) and Asian/Pacific Islander (0.9%).
The bar chart below shows how Sotomayor 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 Sotomayor surname at the time of the 2020 Census, not any inherent property of the name itself.

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.
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.
