Origin
Meaning and origin of Aparico
The surname Aparico originated in Spain during the medieval period. It is derived from the Spanish word "aparicio," which means "apparition" or "vision." This suggests that the name may have been given to someone who claimed to have witnessed a supernatural event or had a religious experience.
One of the earliest recorded instances of the Aparico surname can be found in the Cartulario de San Millán de la Cogolla, a 12th-century manuscript from the Monastery of San Millán de la Cogolla in La Rioja, Spain. This document mentions an individual named Domingo Aparico, who lived in the village of Santurde in the late 11th or early 12th century.
In the 13th century, the Aparico name appeared in several records from the Kingdom of Aragon, including the Liber Feudorum Maior, a cartulary containing records of land grants and feudal obligations. One notable entry mentions a certain Pedro Aparico, who held lands in the village of Alfamén near Zaragoza.
During the 14th century, the surname Aparico spread to other regions of Spain, including Castile and Andalusia. In the Becerro de las Behetrías, a 14th-century census of noble landholdings in Castile, there are references to several individuals with the Aparico surname, such as Juan Aparico, who held lands in the town of Villaverde de Trucios.
In the 15th century, the Aparico name appeared in historical records from the Canary Islands, which were conquered by the Crown of Castile in the late 15th century. One notable individual from this period was Hernán Aparico, a conquistador who participated in the conquest of the island of La Palma in the late 1400s.
Another notable figure with the Aparico surname was Bartolomé Aparico, a Spanish explorer and navigator who accompanied Christopher Columbus on his second voyage to the Americas in 1493. Aparico played a crucial role in the exploration of the Caribbean and is mentioned in several historical accounts from that time.
Throughout the centuries, the Aparico surname has been associated with various place names and local variations in spelling, such as Aparisi, Aparisi Romero, and Aparisi Navarro. Some of these variations may have originated from different regions or dialects within Spain.

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