Irish (especially Ulster): Anglicized form of the Gaelic surname Mac Cú Uladh, a patronymic from Cú Uladh ‘hound of Ulster’. Compare McNally, which is from Mac Con Uladh, genitive form of the same name. It has sometimes been erroneously associated with Gaelic cullach ‘wild boar’, and some families in County Sligo have translated it into English as Boar.
