Origin
Meaning and origin of Bujanda
The surname Bujanda is of Spanish origin, specifically from the Basque region of northern Spain. It is believed to have derived from the name of a small town or village called Bujanda, located in the province of Álava.
The name Bujanda is thought to have its roots in the Basque language, where it may have originated as a descriptive term or a reference to a particular geographical feature. However, the exact etymology and meaning of the name are not entirely clear.
One of the earliest known references to the surname Bujanda can be found in the records of the Monastery of San Millán de la Cogolla, which dates back to the 11th century. This suggests that the name was already in use during the medieval period in the Basque region.
In the 14th century, there are records of individuals with the surname Bujanda residing in the town of Vitoria, which was an important center of Basque culture and politics at the time. This indicates that the name had spread beyond its original location by that point.
Notable individuals with the surname Bujanda throughout history include:
1. Juan de Bujanda (c. 1480-1560), a Spanish theologian and professor at the University of Salamanca.
2. Martín de Bujanda (c. 1520-1590), a Spanish military commander who participated in the conquest of the Philippines.
3. Tomás de Bujanda (c. 1570-1640), a Basque painter known for his religious works in the Baroque style.
4. Joaquín de Bujanda (1789-1868), a Spanish politician and lawyer who served as a member of the Spanish Parliament.
5. María Bujanda (1892-1974), a Basque writer and poet who was part of the literary renaissance in the Basque Country during the early 20th century.
While the surname Bujanda is not among the most common in Spain, it remains a notable part of the country's cultural heritage, particularly in the Basque region, where it has its roots and historical significance.

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