Origin
Meaning and origin of Oseguera
The surname Oseguera has its origins in Spain. It is believed to have emerged during the medieval period, particularly in the regions of Castilla and Aragon. The name is derived from the Spanish word "oseguero," which refers to a person involved in the production or trade of wicker baskets, known as "osegues" in Spanish.
One of the earliest recorded instances of the surname Oseguera can be found in the Becerro de las Behetrias, a medieval census document from the 14th century. This document mentions several individuals with the surname, suggesting its establishment during that time.
Historical records indicate that the Oseguera family played a role in the Reconquista, the centuries-long struggle to reclaim the Iberian Peninsula from Moorish rule. In the 15th century, a notable figure named Juan de Oseguera was recognized for his military service during the conquest of Granada, the last Moorish stronghold in Spain.
In the 16th century, the Oseguera surname gained prominence with the arrival of Spanish colonizers in the Americas. One notable individual was Pedro de Oseguera, a conquistador who accompanied Hernán Cortés in the conquest of Mexico. He later settled in the region and established a lineage of Osegueras in the New World.
Another significant figure was Alonso de Oseguera, a Spanish explorer and navigator who participated in various expeditions throughout the Caribbean and Central America during the early 16th century. His contributions to cartography and exploration helped expand Spain's knowledge of the newly discovered lands.
In the 17th century, the Oseguera family produced several notable members in the field of education and literature. One such individual was Fray Diego de Oseguera, a Franciscan friar and scholar who authored several works on theology and philosophy. His writings were widely recognized and influential during his time.
As the Oseguera surname spread across Spain and its colonies, it underwent various spelling variations, including Osseguera, Oseguera, and Osegura. These variations were often influenced by regional dialects and scribal errors in historical records.
While the surname Oseguera is not among the most common in Spain today, it maintains a presence in various regions, particularly in areas with a historical connection to the basket-making trade or the colonial expansion of the Spanish Empire.

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

Does the Census include every surname?
No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
Why don't the ancestry percentages always add up to exactly 100%?
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
