Oneal is an anglicized form of the Irish surname Ó Néill, meaning 'descendant of Niall'. The personal name Niall, from which it derives, is of uncertain origin but may mean 'champion' or 'cloud'. The surname became prominent through the O'Neill dynasty, a powerful Gaelic Irish family. As a given name, Oneal emerged in the United States in the late 19th century, often used in honor of family heritage.
