McClure is found in both Scottish and Irish records, with closely related Gaelic forms but more than one historical route.
Where does the McClure name come from?
Scottish McClure is generally an anglicised form of Gaelic Mac Gille Uidhir, “son of Gille Odhar,” with the name strongly associated with Galloway. Irish records also preserve Mac Giolla Uidhir, a native Oriel name more often represented by McAleer. The similar Gaelic forms are historically important, but they do not make every McClure and McAleer bearer part of one recent family line.
McClure in Ireland
Some McClure families reached Ulster through Scottish settlement, while Irish surname evidence also records native Mac Giolla Uidhir lines. By the mid-nineteenth century McClure households were especially numerous in Antrim, Down, Armagh and Donegal, with smaller groups elsewhere. A family’s county, denomination and earliest recorded spelling therefore matter more than a single origin story.
