Meaning & origin
Fidencio is a name rooted in Latin, derived from fidentia, meaning 'trust' or 'confidence'. It entered the U.S. baby name records in 1909, and its peak year of popularity was 1928. After a long decline, the name has seen a revival, rising since 2012. As of 2025, it ranks 10,695, with an estimated frequency of 1 in 284,679 newborns. The name is part of a broader recovery of early-20th-century names, especially in Hispanic communities. Despite its rarity, Fidencio carries a positive virtue meaning and a saintly heritage.
Fidencio derives from the Latin name Fidentius, which comes from fidentia meaning 'confidence' or 'trust'. The name was borne by several early Christian saints, including a 3rd-century bishop of the Roman Catholic Church. It has been used in Italy and Spain, where it was particularly common in the late 19th and early 20th centuries, and later among Hispanic communities in the United States.
