Origin
Meaning and origin of Laguerra
The surname LAGUERRA is believed to have originated in Spain during the medieval period. It is derived from the Spanish words "la guerra," which translates to "the war." This suggests that the name may have been given to someone who was involved in a significant conflict or battle.
One of the earliest recorded instances of the LAGUERRA surname can be found in the Libro de las Behetrías, a 14th-century Castilian manuscript that documented the names of landowners and their holdings. This document mentions a Juan de LAGUERRA, who held lands in the region of Burgos.
During the 15th century, the LAGUERRA name appeared in various historical records, including the Repartimiento de Sevilla, a document that listed the distribution of lands and properties in Seville after the city's reconquest from the Moors in 1248. One notable individual mentioned in this record was Rodrigo LAGUERRA, who was granted lands in the region.
In the 16th century, the LAGUERRA surname gained prominence with the birth of Tomás LAGUERRA (1493-1558), a Spanish military commander who served under Charles V during the Italian Wars. Tomás LAGUERRA played a crucial role in the Battle of Pavia in 1525, where he led Spanish forces against the French.
Another prominent figure bearing the LAGUERRA name was Juan LAGUERRA (1539-1605), a Spanish playwright and poet. He is best known for his work "El Caballero de Olmedo," a play that explores themes of honor, love, and betrayal.
In the 19th century, the LAGUERRA surname was associated with Manuel LAGUERRA (1828-1891), a Spanish politician and lawyer who served as the Minister of Justice and later as the President of the Congress of Deputies.
Over time, the LAGUERRA surname has spread beyond Spain to other parts of the world, including Latin America and the United States, where descendants of Spanish immigrants have carried on the name.

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