O'Hare
An Irish surname usually understood as a form of Ó hEathair or Ó hÁir, preserved in an Anglicized spelling with the prefix O'.
The #6,607 most common surname in the United States (2010 Census) — about 1 in every 60,208 Americans shares it.
Etymology
O'Hare is an Anglicized Irish surname. It is generally taken to come from the Gaelic patronymic Ó hEathair, meaning "descendant of Eathar," though older sources sometimes vary in how they analyze the underlying personal name. In English spelling, the Gaelic prefix Ó was often rendered as O' and the rest of the name simplified to match English phonetics.
History
The surname is strongly associated with Ireland, especially Ulster, where many O'-names were preserved or Anglicized under English influence. Like many Irish surnames, it became standardized in several spellings, with O'Hare the most familiar modern form. Bearers of the name can be found in Ireland and among Irish diaspora communities in Britain, North America, and elsewhere.

Fun fact
The apostrophe in O'Hare is a later English spelling convention; in Irish, the prefix Ó is part of the surname rather than a separate word.
