O'Dwyer

The Tribe of O'Dwyer in North America. The surname Odwyer was first found in County Tipperary where they were the traditional Lords of Kilnamanagh. They claim descent from Cairbre Cluitheachar, the youngest son of Cucorb, King of Leinster through the O'Connors (Faley.) [3] Although the O'Dwyers originally held a family seat in the barony of Kilnamanagh, they later branched to Clonyhorpa and Drumdromy in the same county. The eponymous ancestor of the O'Dwyers was Duibhir (sometimes spelled Duibhidir and Dubhiir), [3] the 11th century chief of the sept.
