Origin
The surname Carrasquillo originates from Spain, tracing its roots back to the medieval era. It is derived from the Spanish word "carrasco," which refers to a type of evergreen oak tree native to the Iberian Peninsula. This etymology suggests that the name may have originated in regions where these oak forests were prevalent, possibly in areas like Castile, Aragon, or Andalusia.
One of the earliest recorded instances of the surname Carrasquillo can be found in the archives of the Kingdom of Aragon, where a nobleman named Juan Carrasquillo was mentioned in a land deed from the year 1287. This document suggests that the name had already been established by the late 13th century.
During the Reconquista, the period when Christian kingdoms in the Iberian Peninsula sought to reclaim territories from Moorish rule, many Carrasquillos were involved in military campaigns. One notable figure was Rodrigo Carrasquillo, a knight who fought alongside King Ferdinand III of Castile in the conquest of Seville in 1248.
As Spain expanded its territories through exploration and colonization in the 16th and 17th centuries, the Carrasquillo name spread to various parts of the Spanish Empire. In the New World, one of the earliest recorded Carrasquillos was Pedro Carrasquillo, a settler who arrived in Puerto Rico in the late 1600s and established a plantation there.
Another significant figure from this era was Juana Carrasquillo, a wealthy landowner in the Spanish colony of Santo Domingo (present-day Dominican Republic) in the mid-1700s. Her estate records provide insights into the economic and social status of the Carrasquillo family at the time.
In the 19th century, several Carrasquillos played important roles in the independence movements of Latin American countries. One notable example is José Carrasquillo, a Venezuelan military leader who fought against Spanish colonial rule and later served as a general in the Venezuelan War of Independence under Simón Bolívar.
As the Carrasquillo name spread across different regions and countries, variations in spelling emerged, such as Carrasquilla, Carrasquila, and Carrasquiyo. These variations often reflected local linguistic adaptations or regional dialects.
Overall, the surname Carrasquillo has a rich and diverse history, spanning centuries and continents, with its origins rooted in the medieval Spanish era and its presence felt in various significant historical events and contexts.
Demographics
Among Census respondents with the surname Carrasquillo, the largest self-reported group is Hispanic at 91.6%. The next largest groups are White (6.0%) and Black (1.7%).
The bar chart below shows how Carrasquillo 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 Carrasquillo 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.
