Show ContentsDonnan Surname History

The spelling and overall form of Irish names often vary considerably. The original Gaelic form of the name Donnan 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 Donnan family

The surname Donnan 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

United States Donnan migration to the United States +

The 19th century saw a great wave of Irish migrating out of their homeland in a great measure due to the oppressive imperial policies of the English government and landowners. Many of these Irish families sailed to North America aboard overcrowded passenger ships. By far, the largest influx of Irish immigrants to North America occurred with Great Potato Famine during the late 1840s. These particular immigrants were instrumental in creation of the United States and Canada as major industrial nations because the many essential elements such as the roadways, canals, bridges, and railways required an enormous quantity of cheap labor, which these poor immigrants provided. Later generations of Irish in these countries also went on to make valuable contributions in such fields as the arts, commerce, politics, and education. Extensive research into immigration and passenger lists has revealed many early immigrants bearing the name Donnan:
