Eóin Mac Suibhne

Eóin Mac Suibhne (fl. 1310) was a fourteenth-century Scottish nobleman and a leading member of Clann Suibhne. In the middle of the thirteenth century, seemingly during the 1260s, Eóin's family appears to have been ejected from its homeland in Argyll by the Stewart/Menteith kindred. It may have been during this period that members of Clann Suibhne took up residence in Ireland.

In the first decade of the fourteenth century, Eóin appears on record claiming his family's Scottish lands. As such, Eóin campaigned on behalf of the English cause during the First War of Scottish Independence as a means of combating the Stewarts/Menteiths. An expedition by Eóin to reclaim his ancestral lordship may be referred to by a particular piece of mediaeval Gaelic poetry. Although a sixteenth-century source alleges that Eóin was the first Clann Suibhne Lord of Fanad, contemporary sources appear to show that the family gained the lordship later in the fourteenth century.
