The name Francis has its origins in the Latin language and culture, specifically deriving from the Roman family name Franciscus. This name can be traced back to the Latin word "Francus," meaning "Frankish" or "free." The Franks were a group of Germanic tribes that played a significant role in the later years of the Roman Empire and the establishment of the Frankish Empire in Western Europe.

His life and teachings had a profound impact on the Catholic Church and the name became a popular choice among Catholic families.
