The meaning of Mccullough
Irish (especially Ulster): Anglicized form of Gaelic Mac Cú Uladh, a patronymic from the personal name Cú Uladh ‘hound of Ulster’. Compare McNally, which is from Mac Con Uladh, genitive form of the same name, and McColl, with which the name seems to have sometimes been confused. The name McCullough has sometimes been associated with Gaelic cullach ‘wild boar’, and some families in County Sligo translated it into English as Boar. However, Mac Cú Uladh is the more likely explanation.
