Hernon is a surname. It is of Irish origin, believed to be an Anglicized form of the Gaelic surname Ó hEarnáin. The prefix "Ó" indicates "descendant of," and "Earnán" is thought to be a personal name derived from "Iarann," meaning "iron" or "steel." Thus, the surname Hernon suggests a lineage connected to someone associated with iron, possibly a blacksmith or someone known for strength and resilience. The surname is most commonly found in the western counties of Ireland. Variants of the name include Hearnon, Hearn, and Heron.
