Ambrosio traces back to the Greek ambrosios (“immortal,” “divine”) and the Latin Ambrosius, a name borne by Saint Ambrose, the influential fourth-century bishop of Milan. In Spanish (ahm-BROH-syo, /amˈbrosjo/) and Italian (ahm-BROH-zee-oh, /amˈbrɔzjo/) contexts, it retains strong ecclesiastical and classical overtones. Although its roots lie deep in Southern European tradition, Ambrosio’s usage in the United States has remained modest—seven newborns received the name in 2023, placing it at 922nd in popularity and hardly contending with perennial favorites such as John or Michael. From an analytical standpoint, its steady yet restrained presence over recent decades highlights its appeal among parents seeking a classical appellation with distinctive cachet. By selecting Ambrosio, families invoke a lineage of theological significance while sustaining a unique identity within modern naming conventions.
