ORIGIN & HISTORY

About the name

From Germanic elements generally reconstructed as 'aþal' ('noble') and 'funs' ('ready, eager'), together interpreted as 'noble and ready' or 'eager for battle.'

Alonso (Spanish); ultimately from Germanic *Adalfuns*. Alonzo functions as an Americanized variant of the Spanish name Alonso, itself a variant of Alfonso. The Alonzo spelling became established as an independent English-language form in the United States rather than through direct royal association.
