Mackin
An Irish surname usually taken as a shortened form of Mac Eoin or related Gaelic names, meaning “son of John” or a similar personal-name origin.
The #8,189 most common surname in the United States (2010 Census) — about 1 in every 76,215 Americans shares it.
Etymology
The name is generally treated as an anglicized Irish surname from Gaelic forms such as Mac Eoin, meaning “son of Eoin/John,” though some older sources connect it with related Gaelic forms and local shortenings. The excerpts also show it as a Gaelic family name found in Irish records, especially in Ulster and nearby areas. In practice, Mackin is best understood as a reduced or variant spelling of a longer Mac- surname rather than an independent English word.
History
Nineteenth- and early twentieth-century Irish surname works place Mackin chiefly in Ireland, with references to Monaghan and Ulster. Some reference books note it alongside Macken and other related forms, suggesting regional variation in spelling and pronunciation. It also appears among Irish-American surname listings, reflecting later migration and anglicized record forms.
