MCKEVITT Family History
Recorded in many spelling forms including MacDade, MacDaid, McDavitt, McDevitt, McKevitt, McDade, McDaid and even Davison, this is a surname of Irish origins. It derives from the pre 10th century Gaelic name Mac Daibheid, meaning the son of' David, from the ancient Hebrew name meaning "beloved of all". The nameholders are believed to have descended from David O'Doherty, a chief of Cinel Conaill, who was killed in battel in the year 1208. What is certainly true is that the clan grew to be numerous in the area of Inishowen, in County Donegal.
