The name Anza is of Spanish origin, derived from the Basque word 'anza', which means 'at the end' or 'border'. It gained popularity through the use of Anza Borrego State Park in California, named after José María Rubio Anza, an early settler and rancher. The name Anza carries a sense of finality, closure, and perhaps even a hint of exploration, as it's associated with the park that sprawls across the California desert.
The name Anza saw a 14-year gap between periods of notable usage, with no births recorded from 1996 to 2009. The most recent data suggests a slight increase in popularity since 2010.
