Origin
The surname Roblero originated in Spain during the medieval period. It is believed to have derived from the Spanish word "roble," meaning oak tree, and the suffix "-ero," indicating an occupation or association with oaks. This suggests that the name may have initially referred to someone who worked with oak trees, such as a woodcutter or a carpenter.
The earliest known records of the Roblero surname can be traced back to the 13th century in the regions of Castile and Aragon in Spain. It is possible that the name was initially associated with specific locations or villages where oak trees were abundant or where people worked with oak wood.
In the 14th century, a notable figure bearing the Roblero surname was Juan Roblero, a renowned architect who contributed to the construction of several notable churches and cathedrals in Spain, including the Cathedral of Burgos, which was completed in 1567.
During the 15th century, the Roblero family gained prominence in the region of Andalusia, where they were involved in agricultural and landholding activities. One notable member from this period was Fernán Roblero, who served as a military commander during the Reconquista, the period of Christian conquest over Muslim-ruled territories in the Iberian Peninsula.
In the 16th century, the Roblero surname spread throughout Spain and its colonies in the Americas. One notable figure from this time was Pedro Roblero, a Spanish explorer and conquistador who accompanied Hernán Cortés in the conquest of Mexico in the early 1500s.
As the Spanish Empire expanded, the Roblero surname also found its way to other parts of Europe and the Americas. In the 17th century, a notable figure was María Roblero, a painter and artist from Seville, Spain, who was known for her religious works and portraits.
Over the centuries, the Roblero surname has been associated with various professions and significant historical figures, reflecting the rich cultural and linguistic heritage of Spain and its diaspora around the world.
Demographics
Among Census respondents with the surname Roblero, the largest self-reported group is Hispanic at 97.2%. The next largest groups are White (2.4%) and Black (0.3%).
The bar chart below shows how Roblero 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 Roblero surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Roblero (2000, 2010, 2020).
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.
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.
