Meaning & origin
Guerino is a rare Italian name with a martial meaning. It first appeared in U.S. records in 1913, a few years before its peak in 1918, when it reached its highest recorded usage. Since then, its trajectory has been stable, with very low but consistent use over the decades. The name never broke into the national top 1000 and was never concentrated enough to have top states associated with it. Its rarity makes it a distinctive choice, rooted in Italian heritage and a tradition of warrior-derived names.
Guerino is an Italian given name derived from the Late Latin guerri (warrior), itself from the Germanic element werra (strife, war). It is a diminutive form of Guerino, related to the French Guérin and the Italian Guerriero. The name was borne by several early saints and has been used in Italy since the Middle Ages, though it remains relatively rare.
