Maguire is an Irish surname from the Gaelic Mag Uidhir, which is from Odhar, the eleventh in descent from Colla-da-chrich, great-grandson of Cormac mac Airt, monarch of Ireland about the middle of the third century. Maguire is an uncommon given name. During translation in the Ulster Plantation various English translations of the original Mag Uidhir appeared, including Mc Guire, Maguire, Mac Guire and McGuire. In South West Donegal the name is re-translated into Gaelic as Mac Guibhir.
