Horan
An Irish surname, most often treated as a shortened Anglicized form of Gaelic names beginning with Ó h- / O'-.
The #3,345 most common surname in the United States (2010 Census) — about 1 in every 28,825 Americans shares it.
Etymology
The name Horan is generally explained as an Anglicized Irish surname. The historical spellings in the sources point to Gaelic forms beginning with Ó h- or similar, and modern scholarship commonly treats Horan as a reduced English rendering of an older Irish family name. The exact underlying Gaelic source is not fully certain from these excerpts alone, but the name is clearly Irish in origin and belongs to the large group of surnames reshaped by English spelling and pronunciation.
History
The surname is found in Irish records and was already established enough by the 19th century to appear in regional surname lists. The excerpts connect it with several related spellings such as Haran, Haren, Harhan, and Haughran, showing how fluid the name became in English-language records. It is today especially associated with Ireland and the Irish diaspora, including the United States.
