History & Origin

Alonso is the Spanish form of Alfonso, derived from the Visigothic Germanic name Adelfuns or Hildefons, composed of elements meaning noble or battle and funs meaning ready or prepared. The Visigoths brought this name to Iberia, where it became the preferred royal name of the Asturian, Leonese, and Aragonese kingdoms.

Alonso has been a traditional Spanish name for over a thousand years. Shakespeare used it for the King of Naples in The Tempest (c. 1611), and in the modern era Formula 1 champion Fernando Alonso has kept the name in sporting headlines. In the United States it is used steadily in Hispanic communities.

Did you know? There were thirteen Spanish kings named Alfonso or Alonso between the 8th and 20th centuries, making it one of the most dynastically royal names in Iberian history and giving it a depth of monarchical prestige matched by very few names in Spanish-speaking cultures.
