The surname "VASCOCU" has its origins in the region of Vasconia, an area that encompasses parts of modern-day Spain and France. This name first emerged in the 5th century during the early medieval period when the Vascones, an ancient Iberian tribe, inhabited this region.
The name "VASCOCU" is derived from the Latin word "Vascones," which referred to the people of this tribe. It is believed that the suffix "-cu" was added to denote a person's affiliation with or relationship to the Vascones people.
One of the earliest recorded mentions of the name "VASCOCU" can be found in the Cartulario de San Millán de la Cogolla, a collection of medieval manuscripts from the Monastery of San Millán de la Cogolla in La Rioja, Spain. This document, dating back to the 10th century, includes references to individuals bearing this surname.
In the 11th century, the name "VASCOCU" appeared in the Codex Calixtinus, a medieval manuscript that served as a guide for pilgrims traveling along the Camino de Santiago.

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.
