MCNIFF Family History

Recorded as McNiff, MacNuff, McConniff, McCuniff, Mackniffe, Canniffe, Coneffe, Cunniff, Kinniff, and scarcely recognizeable variants such as Caddo, MacAdoo, MacEndoo and others, this is an Irish medieval surname. Also recorded in Scotland for many generations, but in Ireland originally specific to County Leitrim and parts of Ulster, over the centuries it has been recorded in its varied forms throughout Ireland, although it is doubtfull as to the actual relationship between nameholders. However what does seem to be generally agreed is that however the surname is spelt in the 21st century, it derives from the ancient Gaelic word "con" meaning a hound, and "dubh" - black, to give a translation of the Black Hoiund...
