Origin
Meaning and origin of Grullon
The surname GRULLON is of Spanish origin, with roots tracing back to the medieval period in the regions of Castilla and Andalusia. It is believed to be derived from the Spanish word "grullo," meaning "crane" or "grey," suggesting a connection to a particular physical trait or location.
One of the earliest recorded instances of this surname can be found in the "Cartulario de San Millán de la Cogolla," a 13th-century manuscript documenting historical records in the Rioja region of Spain. The name GRULLON is mentioned in association with a landowner or nobleman from that area.
During the 16th and 17th centuries, the GRULLON name appeared in various historical documents related to the Spanish colonization of the Americas, particularly in the Caribbean islands and parts of Central and South America. This suggests that individuals bearing this surname were among the early Spanish settlers and explorers who ventured to the New World.
Notable figures throughout history who bore the GRULLON surname include:
1. Hernán García de Grullón (c. 1500-1570), a Spanish conquistador and early settler in the island of Hispaniola (present-day Dominican Republic and Haiti).
2. Juan de Grullón y Mendoza (1605-1678), a Spanish military officer and governor of the province of Santa Cruz de la Sierra in modern-day Bolivia.
3. Beatriz de Grullón (1670-1745), a wealthy landowner and philanthropist in the city of Santo Domingo, Dominican Republic, known for her contributions to the construction of churches and support of religious institutions.
4. Antonio de Grullón y Pérez (1785-1860), a Dominican political figure and diplomat who served as the Dominican Republic's first ambassador to the United States in the 1840s.
5. Manuel de Grullón (1822-1899), a prominent Dominican lawyer, writer, and politician who played a significant role in the country's struggle for independence from Spain in the late 19th century.
The GRULLON surname has also been associated with various place names and locations throughout Spanish-speaking regions, such as the town of Grullón in the province of León, Spain, and the Grullón River in the Dominican Republic.

The bar chart below shows how Grullon 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 Grullon surname at the time of the 2020 Census, not any inherent property of the name itself.

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.
