| Black | Very numerous: Ulster, also Dublin and Leinster. Rare in Munster and Connacht. English & Scottish, but also translation of Duff and Kilduff. SI. |
| Ó Duibh | Duff, Black: líonmhar i gCúige Uladh. Is cosúil gur giorrú é ar Ó Duibhinn (Duffin) agus fiú Mac Giolla Dhuibh (Mac Elduff), ach luann de Bhulbh iad mar chlann a bhí suite in aice le Port Laoise. Féach Ó Dubhuidhe. Dar ndó, d'fhéadfadh an sloinne a theacht go díreach ó bhua-aidiacht, cosúil le bán, crón, glas, liath & rl. MIF. |
