McKeever
An Irish surname usually understood as a form of Mac Ivor/MacKeever, ultimately meaning “son of Ivor” or a related Gaelic personal-name form.
The #4,642 most common surname in the United States (2010 Census) — about 1 in every 40,375 Americans shares it.
Etymology
The name is generally treated as an anglicized Irish surname built with Mac- meaning “son of,” attached to a personal name. In older surname lists it appears alongside forms such as MacIver, MacIvor, MacKeever, MacKeevor, and related spellings, suggesting it belongs to that cluster rather than being a separate word-based surname. Some 19th-century writers tried to explain it from Gaelic words meaning “gentle” or “silent,” but that kind of folk etymology is less secure than the patronymic explanation.
History
Spellings with Mc-/Mac- and forms like Keever, Keevor, and Ivor have long varied in Irish records, especially after anglicization. The surname is found chiefly in Ireland and among Irish-descended families abroad, with modern McKeever usually representing one branch of that broader Gaelic surname family. The historical sources provided do not give a single definitive derivation, but they do place McKeever in the same surname group as MacIver/MacIvor.
