Caballero
A Spanish surname meaning “horseman” or “knight,” originally a title for a mounted warrior or nobleman.
The #1,224 most common surname in the United States (2010 Census) — about 1 in every 10,682 Americans shares it.
Etymology
Caballero comes from Spanish caballero, literally “horseman,” built on caballo “horse,” from Latin caballus. In medieval usage, the word came to mean a mounted soldier and then a knight or nobleman of certain rank. As a surname, it likely began as a status-name or nickname for someone associated with knighthood, cavalry service, or gentlemanly rank.
History
The word was a common title in medieval Spain, so the surname could arise independently in more than one family. Historical records show it in Iberian contexts by the late Middle Ages, and it remains especially common in Spanish-speaking regions today. It is also found widely in the Americas through Spanish colonial migration and later movement.

Fun fact
