Makiley is of American origin, derived from the Irish surname McGillicuddy. The name is composed of two elements: 'Mac', meaning 'son of' and 'Gillicuddy', which is a derivative of the Irish given name Gillicadh, itself coming from the Gaelic words 'gille', meaning 'servant', and 'Caoidh', a personal name thought to mean 'victory'. Thus, Makiley can be interpreted as 'son of servant of victory'. The name gained popularity in the United States during the late 20th century.
