Seaán Glas mac Tadhg Riabhach Ó Dubhda
Seaán Glas mac Tadhg Riabhach Ó Dubhda, Chief of the Name and Lord of Tireragh, died c. 1471.
Almost the only document dealing with the succession as the Ó Dubhda chief of the name is Araile do fhlathaibh Ua nDubhda, which presents many chronological difficulties. Even when dates and/or lengths of reigns are given, they can only be appromiximated as some chiefs may have ruled in opposition to each other.
Araile gives Seaán Glas "14" years.
