Origin
Meaning and origin of Herranz
The surname Herranz is of Spanish origin, originating in the regions of Castilla y León and Madrid during the Middle Ages. It is believed to have derived from the Spanish word "herrar," meaning "to shoe" or "to put horseshoes on," suggesting that the name may have been associated with those who worked as blacksmiths or farriers.
The earliest recorded use of the surname Herranz can be traced back to the 13th century in various historical documents from the Kingdom of Castile. One notable mention is in the "Becerro de las Behetrías de Castilla," a medieval register of landholdings and vassals, where the name appears as "Ferrant Herranz."
In the 14th century, the surname Herranz appears in the "Libro de la Montería" of King Alfonso XI of Castile, which recorded the names of nobles and their lands. This document mentions a place called "Herranz" near the town of Hita, in the province of Guadalajara, indicating that the surname may have originated from this location.
During the 15th century, the name Herranz was found in the records of the Inquisition in Toledo, where a certain Juan Herranz was tried for heresy in 1492. This historical reference provides insight into the presence of the surname during the tumultuous period of the Spanish Inquisition.
Notable individuals with the surname Herranz throughout history include:
1. Diego Herranz de Velasco (c. 1600 - 1666), a Spanish writer and playwright from Madrid, known for his works "El Desdén con el Desdén" and "La Comedia Nueva."
2. José Herranz y Quirós (1819 - 1887), a Spanish politician and diplomat who served as the Minister of Foreign Affairs for Spain from 1879 to 1881.
3. Mariano Herranz (1835 - 1910), a Spanish painter and professor at the Royal Academy of Fine Arts of San Fernando in Madrid, known for his religious and historical paintings.
4. Gonzalo Herranz Rodríguez (1924 - 2002), a Spanish businessman and entrepreneur who founded the construction company Sacyr Vallehermoso.
5. Yolanda Herranz Pascual (born 1964), a Spanish mathematician and professor at the Complutense University of Madrid, renowned for her contributions to the field of algebraic geometry.
While the surname Herranz has its roots in medieval Spain, it has since spread to other parts of the world, particularly to Latin American countries, through Spanish colonization and migration.

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