Origin
Meaning and origin of Orduno
The surname Orduno is believed to have originated in the Basque region of northern Spain and southwestern France. It is thought to be derived from the Basque word "ordu," meaning "time" or "hour," and the suffix "-no," which is a common Basque surname ending. The name may have been initially given to someone who had a specific task or duty related to keeping time or following a schedule.
One of the earliest recorded instances of the name Orduno can be found in the Becerro Galicano, a Spanish census document from the late 13th century. Here, the name appears as "Ordunno," likely reflecting an older spelling variation.
In the 14th century, records show an Orduno family residing in the town of Lequeitio, located in the Basque province of Biscay (Bizkaia). This town was known for its shipbuilding industry, and it is possible that members of the Orduno family were involved in this trade.
During the 15th century, the name Orduno began to spread beyond the Basque region. In 1487, a man named Juan de Orduno was listed as a resident of the city of Seville in southern Spain. This suggests that the name had started to migrate as people moved within the Iberian Peninsula.
One notable individual with the surname Orduno was Pedro de Orduno, a Spanish soldier and explorer who participated in the conquest of Mexico alongside Hernán Cortés in the early 16th century. He was born around 1490 in the town of Orduna, located in the Basque Country.
Another significant figure was Francisco de Orduno, a Spanish architect and engineer who lived in the 17th century. He was responsible for designing several notable buildings in Madrid, including the Colegio Imperial de la Compañía de Jesús (Imperial College of the Company of Jesus).
In the 18th century, a man named José Orduno was a prominent painter in Mexico, known for his religious artwork and portraits. He was born in 1720 and worked in the city of Puebla.
Towards the end of the 19th century, a Spanish writer and journalist named Miguel Orduno Lafuente gained recognition for his literary works, including novels and plays. He was born in 1862 in the city of Zaragoza.
Finally, in the 20th century, Jesús Orduno Arregui was a Mexican businessman and philanthropist who founded the Orduno Foundation, dedicated to promoting education and social welfare initiatives. He was born in 1900 and passed away in 1986.

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 Orduno 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 Orduno (2000, 2010, 2020).
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.
