Alonsa is Spanish in Origin.

Alonsa is the feminine counterpart of Spanish Alonso, itself a medieval form of Alfonso, ultimately from the Visigothic Adalfuns/Alfuns (adal “noble” + funs “ready, prepared”). The name thus conveys “noble and ready” or “noble readiness,” often glossed as “ready for battle” in older sources. Formed by the simple -a feminization typical of Spanish naming, Alonsa parallels Alfonsa and the more elaborate Alfonsina.

Usage traces to early modern Iberia and colonial Latin America, where feminized forms of male family names appeared in legal and baptismal records, though Alonsa has always been rare. Today it offers a distinctive, streamlined alternative to Alfonsa/Alfonsina. Variant spellings include Alonza; related masculine forms are Alonso, Alonzo (English/Italianate), Alfonso (Spanish/Italian), and Afonso (Portuguese). Nickname options include Lona and Alon; in Spanish contexts, Fonsi more often attaches to Alfonso-based forms.
