Origin
Meaning and origin of Huidor
The surname "HUIDOR" traces its origins back to the Basque region of northern Spain and southwestern France during the medieval period. It is believed to be derived from the Basque word "huidoi," which means "to flee" or "to escape." This suggests that the name may have been given to someone who had fled or escaped from some sort of conflict or persecution.
One of the earliest recorded instances of the name "HUIDOR" appears in a 14th-century manuscript from the village of Lekeitio in the Basque Country. The document mentions a certain Sancho Huidor, who was a local landowner and prominent figure in the community.
In the 16th century, the name "HUIDOR" can be found in the records of the Inquisition in Spain. A man named Juan Huidor was accused of harboring Protestant sympathies and was brought before the Inquisition in Seville in 1567. He was eventually exonerated, but the incident highlights the presence of the name in that period.
During the 17th century, the name "HUIDOR" seems to have spread beyond the Basque region. A notable bearer of the name was Pedro Huidor, a Spanish explorer who accompanied the famous conquistador Hernán Cortés on his expedition to Mexico in the early 1500s.
In the 18th century, the name "HUIDOR" appears in connection with the Basque whaling industry. A certain Martín Huidor was a prominent whaler from the town of Bermeo, and his name is mentioned in several logbooks and records from that era.
Another notable figure with the surname "HUIDOR" was Juana Huidor, a Basque writer and poet who lived in the late 19th century. She was known for her works that celebrated Basque culture and language.
While the surname "HUIDOR" originated in the Basque region, it has since spread to other parts of Spain and beyond, though it remains relatively uncommon outside of its traditional homeland.

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