O'Bryant
An Irish surname that likely began as a patronymic form of Bryant, ultimately tied to the personal name Brian.
The #8,283 most common surname in the United States (2010 Census) — about 1 in every 77,167 Americans shares it.
Etymology
O'Bryant is usually understood as an Anglicized form of the Irish patronymic O Briain, the name behind English Bryant. The initial O' means 'descendant of,' while Brian is a Gaelic personal name widely associated with the meaning 'high' or 'noble' in traditional explanations. In practice, O'Bryant can also reflect later spelling variation and simplification, especially in English-speaking records.
History
The surname is part of the broad family of names descended from Brian Boru and the Irish O'Brien tradition. In emigration and English-language record keeping, spellings often shifted, and forms like O'Bryant, O Bryant, and Bryant could overlap or be used interchangeably. The modern U.S. distribution reflects that history of anglicization and variant spelling.
