The Darmody name is spelt as Darmody and Dermody in Ireland. Some variations of the name are Dirmody,Dormody and Durmody and because of the similarity in pronunciation, some Darmody and Dermody immigrants may have had their names recorded incorrectly in official documents.
"DERMODY, DARMODY: O'Diarmada. A fairly numerous but scattered name mainly in counties Cavan, Westmeath, Kilkenney and Galway; in the latter though spelt Dermody it is pronounced Darmody."
