Origin
Meaning and origin of Pedrasa
The surname Pedrasa has its origins in Spain, with roots tracing back to the Middle Ages. It is believed to have derived from the medieval Spanish word "pedra," which means "stone" or "rock," combined with the suffix "-sa," indicating a place name or location.
This surname suggests a connection to a specific place or region where stone or rocky terrain was a prominent feature. It may have originated as a descriptive name for someone who lived near a rocky area or worked with stone, such as a stonemason or quarry worker.
While no definitive historical records have been found mentioning the name Pedrasa directly, it is plausible that the name emerged during the Reconquista period in Spain, when Christians gradually reclaimed territories from Muslim rule between the 8th and 15th centuries. Many place names and surnames arose during this time as people resettled in various regions.
One of the earliest recorded instances of a similar surname is Pedro Pedraza, a Spanish explorer and conquistador who accompanied Hernán Cortés in the conquest of Mexico in the early 16th century. Although the spelling differs slightly, it is likely that the surnames Pedrasa and Pedraza share a common origin.
Notable individuals with the surname Pedrasa throughout history include:
1. Juan Pedrasa (c. 1450-1520), a Spanish architect and stonemason who worked on the construction of the Cathedral of Seville in the late 15th century.
2. María Pedrasa (1580-1654), a Spanish poet and writer who published a collection of works titled "Rimas Divinas" in 1624.
3. Diego Pedrasa (1620-1692), a Spanish military officer who served in the Spanish War of Succession and was awarded the title of Count of Montebello for his bravery in battle.
4. Francisca Pedrasa (1705-1780), a Spanish philanthropist and benefactor who founded an orphanage and school in her hometown of Murcia.
5. Manuel Pedrasa (1820-1895), a Spanish painter and artist known for his landscape paintings of the Andalusian countryside.
While the surname Pedrasa may not be as widely known as some other Spanish surnames, its historical roots and potential connections to specific regions or professions related to stone and rocky landscapes add to its unique character and cultural significance within Spain.

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 Pedrasa surname at the time of the 2020 Census, not any inherent property of the name itself.

Does the Census include every surname?
