O'Hare or O'Heare is the anglicised form of the Irish surname Ó hÍr. The name is found on both sides of the Irish sea and may be either Irish or Scottish. Recorded as O'Hare and O'Hair, sometimes McHare, or Hare or Hair, this is a famous Irish clan surname. It is said to have been one of the few surnames to resist the temptation in the 17th century to discard the Gaelic prefix O', meaning male descendant of. Nevertheless, there has been and there remains considerable confusion in Ireland as to the true origin because many English and Scottish settlers were also called Hare or Hair.
