Show ContentsDugnan Surname History

The spelling and overall form of Irish names often vary considerably. The original Gaelic form of the name Dugnan is Ó Dunain. The name is thought to have originally been derived from the word "donn," which meant "brown." 1

Alternatively, the name could have been derived from the Irish Gaelic Ó Duibhgenain which roughly translates into English as follows: "dubh" as "black of dark;" "gen" as "a sword or wound;" and "an" as "one who." 2

Early Origins of the Dugnan family

The surname Dugnan was first found in Roscommon, where they held a family seat at Kilronan. 2 One of the first records of the name was Saint Donnán of Eigg (died 617) and Irish Gaelic priest who attempted to introduce Christianity to the Picts of northwestern Scotland. Donnán is the patron saint of Eigg, an island in the Inner Hebrides where he was martyred. Later, Maelmuire O Dunain, was Bishop of Meath (1096-1117.) The next listing was of Adam O'Dounan in a County Roscommon land case in 1299. 1 Shortly after, Ferrall Muinach O'Duignan began the Church of Kilronan in 1339. This church, over looking Lake Meelagh, was of great national interest in that it is reportedly the burial place of Carolan. John Ballach O'Dugenan was chief of his Clan when they were dispossessed of their estates in Kilronan.

They later were landed gentry in the parish of Dromleas, in the barony of Drumaheare, county of Leitrim, estates which they held until the Cromwellian confiscations in the 17th century. They were noted for their great contributions to history and literature. Manus O'Duigenan contributed to the Book of Ballymote, sometimes called the Book of Kilronan, or the Book of the O'Duigenans, which became one of the chronicles of the Four Masters. 2
