Origin
Meaning and origin of Maurillo
The surname Maurillo is of Spanish origin, with roots that can be traced back to the 15th century. It is believed to have originated in the region of Andalusia, specifically in the town of Maurillo, located in the province of Seville. This place name is derived from the Latin word "maurus," meaning "Moor" or "dark-skinned," suggesting a possible connection to the Moorish influence in the area during the period of Muslim rule in Spain.
One of the earliest recorded instances of the surname Maurillo can be found in the baptismal records of the Church of Santa María la Blanca in Seville, where a certain Juan Maurillo was listed in the year 1487. Another notable mention is in the Catastro de Ensenada, a census-like document from 1752, which included several families with the surname Maurillo residing in the town of Maurillo and nearby villages.
The name Maurillo also appears in several historical documents from the 16th and 17th centuries, such as land registries and legal proceedings. For instance, a certain Pedro Maurillo was mentioned in a legal dispute over a property transaction in the town of Écija in 1612.
Throughout history, there have been a few notable individuals who carried the surname Maurillo. One such person was Rodrigo Maurillo de Lara (1565-1638), a Spanish military officer who participated in the Conquest of Granada and later served as the governor of the Canary Islands. Another was María Maurillo Pérez (1720-1789), a renowned poet and writer from Seville, whose works were widely acclaimed during her lifetime.
Other individuals of note include Francisco Maurillo Gutiérrez (1810-1876), a prominent lawyer and politician who served as a member of the Spanish parliament in the mid-19th century, and Ana Maurillo Castillo (1875-1952), a pioneering educator who established several schools in the region of Andalusia and advocated for women's education.
More recently, Juan Maurillo Hernández (1920-2002) was a distinguished artist and sculptor, known for his works in bronze and marble, which can be found in various museums and public spaces throughout 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 Maurillo surname at the time of the 2020 Census, not any inherent property of the name itself.
