Origin
Meaning and origin of Edalgo
The surname EDALGO is of Spanish origin, tracing its roots back to the medieval era in the Iberian Peninsula. It is believed to have derived from the Spanish word "hidalgo," which referred to a member of the lower nobility or gentry class. This term originated from the Latin phrase "filius de aliquo," meaning "son of someone."
The earliest recorded instances of the name EDALGO can be found in historical documents from the 13th and 14th centuries in regions like Castile and Aragon. It is possible that the name was initially associated with individuals who held positions of minor nobility or were landowners in these areas. Some variations in spelling, such as "Hydalgo" or "Idalgo," were also common during this time period.
In the 15th century, a notable figure bearing the name EDALGO was Diego Edalgo, a Spanish explorer and navigator who accompanied Christopher Columbus on his second voyage to the Americas in 1493. Another prominent individual was Juan Edalgo, a military captain who fought in the Reconquista against the Moors in the late 15th century.
The name EDALGO has also been linked to several place names in Spain, such as the town of Hidalgo in the province of Palencia. These locations may have been named after individuals bearing the surname or vice versa, reflecting the historical connection between the name and landholdings.
During the 16th and 17th centuries, as Spain expanded its influence across the globe, the EDALGO name spread to various parts of the Spanish Empire. For instance, Pedro Edalgo (1523-1589) was a Spanish conquistador who participated in the conquest of Peru and later served as a governor in present-day Mexico.
Another notable figure was María Edalgo (1612-1679), a Spanish nun and writer who authored several religious works and was known for her piety and literary contributions during the Golden Age of Spanish literature.
As the centuries passed, the EDALGO surname continued to be carried by individuals from diverse backgrounds, including artists, scholars, and military figures. For example, Javier Edalgo (1781-1846) was a Spanish painter renowned for his portraits and historical scenes, while Emilio Edalgo (1893-1972) was a celebrated linguist and academic who made significant contributions to the study of ancient languages.

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

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
