Origin

Meaning and origin of Arau

The surname ARAU originated in the Basque region of northern Spain and southern France. It is believed to be derived from the Basque word "arau," which means "rule" or "law." The name first appeared in written records during the early medieval period, around the 8th to 10th centuries.

One of the earliest known bearers of the name was Fortun Arau, a Basque nobleman who lived in the 9th century and was mentioned in chronicles from the Kingdom of Navarre. Another early record is found in a 10th-century cartulary from the monastery of San Juan de la Peña, which listed a landowner named Sancho Arau.

The name was particularly prevalent in the region of Guipúzcoa, where it is thought to have originated from a place name or a descriptive nickname related to the concept of law or authority. Several villages and hamlets in the area had variations of the name, such as Arauz, Arauzo, and Arauzo de Torre.

In the 12th century, during the height of the Reconquista, a knight named Pedro Arau is recorded as participating in the siege of Seville alongside King Ferdinand III of Castile. His descendant, Martín Arau, was a prominent figure in the court of Alfonso X the Wise in the 13th century and is mentioned in several royal charters.

As the Basque people migrated and dispersed over the centuries, the surname ARAU spread to other parts of Spain, as well as to the Americas during the colonial period. Notable bearers of the name include Juan de Arau, a 16th-century explorer and navigator who accompanied Hernán Cortés on his expedition to Mexico, and Catalina Arau, a 17th-century writer and poet from Seville.

In more recent history, the ARAU surname has been carried by individuals such as Alfonso Arau, a Mexican film director and actor born in 1932, and Emmanuelle Arau, a French actress born in 1968. The name has also been found in various forms, such as Araux and Arauz, among families of Basque descent in countries like France, Argentina, and the United States.

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.
