Origin
The surname MADRUENO has its origins in Spain, specifically in the region of Castile. It is believed to have emerged during the medieval period, around the 12th or 13th century. The name is derived from the Spanish word "madrugar," which means "to rise early." This suggests that the original bearers of this surname may have been early risers or those who were known for their diligent and industrious nature.
One of the earliest recorded mentions of the MADRUENO surname can be found in the Becerro de las Behetrías de Castilla, a 14th-century census document from the Kingdom of Castile. This document recorded the names of landowners and their properties, providing valuable insights into the distribution and prevalence of surnames during that time.
The MADRUENO surname has also been linked to certain place names in Spain. For instance, there is a village called Madruedano in the province of Segovia, which may have influenced the spelling and pronunciation of the surname over time.
Among the notable individuals who bore the MADRUENO surname throughout history, one can mention Hernán Madrueño, a Spanish conquistador who participated in the conquest of Peru in the 16th century, serving under Francisco Pizarro. Another notable figure was Juan Madrueño, a 17th-century Spanish painter known for his religious works and portraits.
In the 18th century, José Madrueño y Guzmán, a Spanish military officer and colonial administrator, served as the governor of Panama and later as the viceroy of New Granada (present-day Colombia and Panama).
Moving into the 19th century, Ramón Madrueño was a Spanish politician and lawyer who played a significant role in the drafting of the Spanish Constitution of 1869.
Finally, in the 20th century, one can mention Enrique Madrueño Aguado, a Spanish philologist and linguist who made significant contributions to the study of Basque language and literature.
While the MADRUENO surname has its roots in Spain, it has since spread to other parts of the world, particularly Latin American countries, due to Spanish colonization and migration patterns. However, its historical significance and origins remain firmly rooted in the Iberian Peninsula.
Demographics
Among Census respondents with the surname Madrueno, the largest self-reported group is Hispanic at 90.1%. The next largest groups are White (7.2%) and Asian/Pacific Islander (0.9%).
The bar chart below shows how Madrueno 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 Madrueno surname at the time of the 2020 Census, not any inherent property of the name itself.

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.
