Early notable instances include Melchiorre Guerriero, a wealthy landowner in Campagna (SA) during the late 1400s, and Monsignor Nicola Guerriero, Bishop of Scala in the 1700s. The name also appears in Lombardy, with figures such as Count Guerriero Lana in the 1500s and Count Guerriero Gambaresco in the 1600s at Gambara (BS).
