O'riley

O'Riley is a masculine surname-turned-first name of Irish origin. It's derived from the Gaelic surname Ó Raghailligh, meaning "descendant of Raghallach," a personal name thought to mean "valiant" or "rash in battle." The O' prefix traditionally denotes "grandson of" or "descendant of" in Irish naming traditions. As a first name, O'Riley represents the ongoing trend of using family surnames as given names, particularly in Irish-American communities. While not among the most common given names, it offers a distinctive option that honors Irish heritage while maintaining a contemporary feel.
