Keeney
An Irish surname most likely related to names like Keane and Keenan, with the spelling shaped by anglicization and dialect.
The #3,813 most common surname in the United States (2010 Census) — about 1 in every 33,220 Americans shares it.
Etymology
Keeney is generally treated as an Anglicized Irish surname. The historical forms cited alongside it point to Irish Gaelic names such as O'Ciainai5 and O'CiATiAin, which were rendered in English as Keeney, Keaney, Keany, Keenan, and related spellings. The name is therefore best understood as an English spelling of an Irish family name whose original Gaelic form and exact derivation are not entirely certain from the excerpted sources alone.
History
The surname appears in several Anglicized Irish spellings, showing how one Gaelic name could be recorded in different English forms by different clerks or branches of a family. In Irish-American usage, Keeney often overlaps with Keaney, Keany, and Keenan, reflecting local pronunciation and spelling drift. The later source also treats Keeney as matching the German surname Kuehne in sound, but that is about English spelling practice rather than the surname’s true origin.
