Origin
Meaning and origin of Lagrua
The surname LAGRUA has its origins in Spain, originating in the late 15th century. It is believed to have derived from the Spanish word "laguna," meaning "lagoon" or "lake," possibly indicating that the earliest bearers of this name lived near a body of water. Alternatively, it may have been a topographical name referring to a person who lived in a marshy or swampy area.
One of the earliest recorded instances of the LAGRUA surname can be found in the municipal records of Seville, Spain, dating back to 1492. These records mention a certain Pedro LAGRUA, who was a landowner in the region. Another early reference is a 1518 document from the archives of the city of Granada, which mentions a Juan LAGRUA, a merchant involved in the trade of spices and textiles.
In the 16th century, the LAGRUA family appears to have been prominent in the area around Córdoba, with several members holding positions of influence in local government and the church. One notable figure was Alonso LAGRUA, who served as the mayor of Córdoba in 1573.
As the Spanish Empire expanded, the LAGRUA name spread to other parts of the world, including the Americas. In the late 17th century, a Francisco LAGRUA was among the first Spanish settlers in the region that would become New Mexico. His descendants went on to establish the town of Laguna, which may have been named after their surname.
In the 19th century, a notable bearer of the LAGRUA name was Miguel LAGRUA (1835-1902), a Spanish painter and teacher who was part of the Catalan Modernist movement. Some of his works can be found in the Museu Nacional d'Art de Catalunya in Barcelona.
Other historical figures with the LAGRUA surname include:
1. Bartolomé LAGRUA (1570-1638), a Spanish Catholic priest and theologian.
2. María LAGRUA (1776-1854), a Spanish composer and pianist active in the early Romantic period.
3. José LAGRUA (1820-1892), a Spanish politician and lawyer who served as a member of the Congress of Deputies.
4. Emilio LAGRUA (1878-1938), a Cuban writer and journalist known for his works on Latin American culture and history.
5. Catalina LAGRUA (1902-1986), a Mexican artist and painter associated with the Muralist movement.

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

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.

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
