Mac AMHALGHADHA, Mac AMHALGHAIDH—IV—MacAulay, MacAuley, MacCauley, MacCowley, Cawley, etc.; 'son of Amhalghaidh' (an ancient Irish personal name). There are several distinct families of this name, the best known being that of Co. Westmeath, the head of which was formerly lord of Calraighe, comprising the whole of the parish of Ballyloughloe, in the west of that county. It is sometimes impossible to distinguish the anglicised forms of this surname from those of Mac Amhlaoibh, which see. See also Mag Amhalghadha, which is a variant.
