Origin
Meaning and origin of Aguerre
The surname Aguerre is of Basque origin, originating from the Basque Country which spans parts of northern Spain and southwestern France. It likely emerged during the medieval period, around the 11th or 12th century.
The name Aguerre is believed to derive from the Basque words "agur" meaning "hello" or "greeting", and "erri" meaning "town" or "village". This suggests the name may have originally referred to someone who came from a hospitable town or village known for its welcoming nature.
One of the earliest recorded instances of the surname Aguerre can be found in the medieval Basque records known as the "Fueros de Navarra" from the 13th century. These legal documents mention individuals with the surname Aguerre residing in the Basque regions of Navarre and Gipuzkoa.
In the 15th century, a prominent figure named Juan de Aguerre was a notable merchant and shipowner from the coastal town of Getaria in Gipuzkoa. He is mentioned in various maritime records of the time, highlighting the historical presence of the surname in the region.
During the 16th century, the Aguerre family had a strong presence in the town of Azpeitia, also in Gipuzkoa. One notable individual was Pedro de Aguerre (1510-1578), a wealthy landowner and local authority figure who played a role in the social and political affairs of the town.
In the 17th century, the surname Aguerre appeared in records from the neighboring Basque region of Labourd, in what is now southwestern France. Documented examples include Marie Aguerre (1622-1689), a respected businesswoman and landowner from the town of Ustaritz.
The 18th century saw the Aguerre family establish a presence in the New World, with members migrating to Spanish colonial territories. One such individual was José Aguerre (1745-1821), a military officer who served in the Spanish colonies of Florida and Cuba.
Throughout its history, the surname Aguerre has maintained its Basque roots and cultural connections to the Basque Country, despite its spread to other regions over time. Notable individuals with the surname have contributed to various fields, including commerce, politics, and military service.

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