I am originally from near Castleblayney, Co. Monaghan. The people mentioned by Maureen (Cromie) Parker were my grand-uncles and Kernans are quite numerous in the area mentioned. More generally the Kernan name is found in South Ulster - mainly in counties Cavan, Monaghan, Armagh and Fermanagh so if you have that surname it is quite likely that your ancestors come from that region of Ireland. The most common first names found among my ancestors over the past three generations are John, Edward (Ned), Christopher , Felix and Thomas. (I mention this because the same first names tend to recur in Irish families though that is now changing) By the way, I can vaguely recall my late father (Felix Kernan) at various times talking of the Cromie family - one may been a James Cromie?? Hope this helps.
