Origin
The surname Aldave originates from the Basque region of northern Spain and southwestern France. It is derived from the Basque words "alde" meaning side or slope, and "aue" meaning meadow or pasture. This suggests that the name likely referred to someone who lived on the slope of a meadow or pasture.
The earliest known record of the Aldave surname dates back to the 12th century in the village of Aldave, located in Navarre, Spain. This village name is believed to be the source of the surname. In the medieval era, it was common for people to adopt surnames based on the place they were from.
One of the earliest recorded instances of the Aldave surname appears in a 13th-century document from the Kingdom of Navarre, which mentions a landowner named Juan de Aldave. This suggests that the name had already established itself as a prominent surname in the region by that time.
In the 16th century, the Aldave family played a significant role in the political and military affairs of the Basque region. Juan Aldave (1520-1587) was a notable military leader who fought in various battles against the French during the Navarrese War of Independence.
Another prominent figure with the Aldave surname was Pedro de Aldave (1570-1638), a Spanish explorer and navigator who accompanied several expeditions to the Americas. He is credited with mapping parts of the Pacific coast of Mexico and establishing settlements in what is now California.
During the 17th and 18th centuries, the Aldave surname spread beyond the Basque region as members of the family migrated to other parts of Spain and its colonies in the Americas. One notable individual from this period was Ignacio de Aldave (1675-1741), a Spanish military officer who served as the governor of Puerto Rico from 1735 to 1741.
In the 19th century, the Aldave surname gained wider recognition with the birth of Manuel Aldave (1810-1880), a celebrated Chilean poet and writer. His works, which often explored themes of nature and rural life, played a significant role in shaping the literary landscape of Chile.
Throughout its history, the Aldave surname has maintained a strong presence in the Basque region and has also been carried to various parts of the world through migration and exploration. While its origins can be traced back to a specific village in Navarre, the name has become a part of the cultural heritage of multiple countries and communities.
Demographics
Among Census respondents with the surname Aldave, the largest self-reported group is Hispanic at 73.5%. The next largest groups are White (11.3%) and Asian/Pacific Islander (11.3%).
The bar chart below shows how Aldave 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 Aldave surname at the time of the 2020 Census, not any inherent property of the name itself.
