Etymology
Alonso is a Spanish surname that originally meant “son of Alonso” or, more broadly, “descendant of Alonso.” The personal name Alonso is a medieval Spanish form of Alfonso, a name of Germanic origin usually explained from elements meaning something like “noble” and “ready” or “eager.” In historical spelling, Alonso and Alfonso could vary a great deal, and the surname grew out of that given name rather than from a place or occupation.
History
The surname is widespread in Spain and across the Spanish-speaking world, reflecting the long popularity of the personal name Alonso/Alfonso in medieval Iberia. The excerpts also show the name discussed as a patronymic in older Spanish scholarship, where it is treated as a family name formed from the personal name. In modern usage it remains one of the better-known Spanish surnames in the Americas as well as in Spain.
