Origin
Meaning and origin of Caha
The surname CAHA has its origins in the Iberian Peninsula, specifically in the regions of Catalonia and Valencia, Spain. The name is believed to have derived from the Latin word "callis," meaning "path" or "road," which later evolved into the Spanish word "calle" (street). This suggests that the name may have originally referred to someone who lived near a particular road or path.
One of the earliest recorded instances of the name CAHA can be traced back to the late 13th century, when it appeared in the "Llibre del Repartiment," a historical document that recorded the distribution of lands and properties after the Christian conquest of Valencia in 1238. This document mentions a certain Domingo Caha, who was granted a parcel of land in the region.
In the 15th century, the name CAHA appeared in various municipal records and historical documents from the regions of Catalonia and Valencia. For instance, a notable figure from this time period was Pere Caha, a merchant and landowner from the city of Barcelona, who lived between 1420 and 1492.
During the 16th and 17th centuries, the name CAHA spread to other parts of Spain, as well as to the Spanish colonies in the Americas. One prominent individual bearing this surname was Diego Caha, a Spanish conquistador and explorer who accompanied Hernán Cortés in the conquest of Mexico in the early 16th century.
Another historical figure was Juan Caha, a Catalan artist and sculptor who lived from 1585 to 1647. He is best known for his works in the Baroque style, particularly the intricate altarpieces he created for churches in Barcelona and its surrounding areas.
In the 18th century, the name CAHA continued to be documented in various Spanish records and documents. A notable bearer of this surname was María Caha, a writer and poet from Valencia, who lived between 1720 and 1789. Her works, which often explored themes of love and nature, were widely acclaimed during her lifetime.
As the centuries passed, the CAHA surname spread further across the Spanish-speaking world, with many individuals bearing this name making significant contributions to various fields, including art, literature, and politics.

The bar chart below shows how Caha bearers described their own race and ethnicity on the 2020 Census form. 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 Caha surname at the time of the 2020 Census, not any inherent property of the name itself.

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