Aloysius is an uncommon given name of Latin origin, derived from the Roman family name Aemilius, which was thought to mean "excellently spoken." The name Aloysius was popularized by Saint Aloysius Gonzaga (1568-1591), a young Italian nobleman who gave up his inheritance to become a Jesuit priest. He is venerated as the patron saint of youth and squires, which may have contributed to the name's historical popularity among Catholic families. Today, Aloysius remains an uncommon but distinctive choice for parents seeking a unique and meaningful name for their child.
