Thomas Butler, 1st Baron Cahir
Thomas Butler, 1st Baron Cahir or Caher was an Irish peer.
Butler was the son of Thomas Butler of Cahir and Catherine Power. He was elevated to the peerage of Ireland, 10 November 1543, by the title of Baron of Caher. He married Eleanor Butler, fifth daughter of Piers Butler, 8th Earl of Ormond. He lived in Cahir Castle and ruled much of the barony of Iffa and Offa West.
The Baron died in 1558 and was succeeded by his only surviving son and heir, Edmund Butler, 2nd Baron Cahir who died himself two years later. As he had no legitimate male heirs, the title became extinct. It was, however, revived in favour of his first cousin, Theobald Butler, 1st Baron Cahir.
