The history of the last name Haro

The surname HARO originated in Spain, specifically in the northern region of Cantabria. It traces its roots back to the 9th century and the Old Spanish word "haro," which meant "boundary marker" or "frontier."

The name is believed to have originated from a place name, possibly the village of Haro or the nearby Monastery of Santa María la Real de Haro, both located in the province of La Rioja. The earliest recorded instances of the surname HARO can be found in medieval documents from the 11th and 12th centuries.

One of the earliest notable bearers of the name was Lope Díaz de Haro, a powerful nobleman and ruler of Vizcaya in the 13th century. His son, Diego López de Haro, was a prominent figure during the reign of King Alfonso X of Castile and León, serving as his trusted advisor and ambassador.

In the 14th century, Juan Núñez de Lara y Haro, a member of the powerful Lara family, was granted the title of Count of Haro by King Alfonso XI of Castile. This further solidified the surname's association with the region and its nobility.

Another notable figure bearing the HARO name was Pedro Fernández de Haro, a 15th-century Spanish military commander who played a significant role in the conquest of the Canary Islands. He was appointed as the first governor of the islands by the Catholic Monarchs, Ferdinand and Isabella.

During the colonial era, the HARO surname spread to the Americas, particularly to Mexico and other Spanish territories. One prominent individual was Pedro de Haro, a Spanish explorer and soldier who participated in the conquest of Nueva Galicia (present-day western Mexico) in the 16th century.
