. Corcu Baiscin was held by the descendants of Carbry Bascain until the 11th Century, when the descendants of Mahon O’Brien conquered them. According to Frost, Mahone 'a quo MacMahon' died in 1129, leaving two sons Murtagh and Dermot, with Murtagh being the ancestor of the main line of McMahons in Clare. The McMahons seized the Corcabaskin territory in the south of what is now County Clare in the 12th century about the same time as they adopted the fixed surname. Quoting the "Annals of the Four Masters", Frost says that Donogh MacMahon, Lord of Corcabaskin, died in 1488 and two MacMahons, Brian and Teige Roe, were established in his place – Brian in West Corcabaskin (known as Moyarta) and Teige Roe in the East (known as Clonderalaw).

and Clonderlaw Castle, are prominent landmarks and a source of local interest today. In August 1585, the Irish leaders of Thomond were forced to sign an Indenture with Sir John Perrott, the English Lord Deputy of Ireland. Frost says that "some of the signatories of the Deed of Composition seem to have been bribed into conformity by Perrott ... ncluding Teige MacMahon ... of Clonderalaw [andTurlough MacMahon ... of Moyarta". They were allowed to retain their castles and lands free of crown rent. The two MacMahons would have received the English titles of Baronet, replacing their traditional Irish titles, about this time. The two sons who succeeded them as heads of their families certainly each carried the English title. The last chief of the West Corcabaskin MacMahons, Sir Teige Caech MacMahon, was killed at or shortly after the battle of Kinsale in 1602, and his title became extinct. Sir Turlough Roe MacMahon, Baronet of East Corcabaskin, received the honour of becoming High Sheriff of County Clare in 1609. He died in 1629. According to an Inquisition held at Ennis in 1630 (reported in Frost's "History ... of Clare"), Turlough's title was inherited by his eldest son, Sir Teige MacMahon. Sir Teige (or Teague) represented the Earl of Thomond in negotiations with Sir William Penn in 1646, but in 1651 General Ireton seized Clonderlaw Castle from Sir Teige. Frost's "History" records 31 Townlands in County Clare being seized from Sir Teague. James Barry's "The Cromwellian Settlement of the County of Limerick" mentions Sir Teague MacMahon as the holder of other lands in that County. There is evidence that Sir Teague had a son called Turlough (or Terlagh). Honour, Lady Dowager of Kerry and Lixnaw, was granted the "guardianship and tuition of Torlogh MacMahon, son and heir to Teague MacMahon" on 27 June 1673 (recorded in MS Carte 38, fol(s) 742v (Carte Caleb=ndar Vol 52, 1673–1674, Bodleian Library, Uni of Oxford). Ainsworth's edited Inchiquin Manuscripts, MS No 1845, at p. 625, contains a note made following the death of Mary Rua O'Brien in 1686 which refers to "her nephew Sir Terlagh McMahon". The title appears to have died out with him. After the defeats of the native Irish in the 17th century, many of the Clare MacMahons emigrated to serve in the Irish Brigade of the

It was a MacMahon, Colonel Hugh Oge's loose lips that were responsible for letting slip the plot to seize Dublin Castle. He had drunkenly told his Protestant foster brother Owen Connolly, who subsequently betrayed him and he was captured. With the help of two priests and a Scottish maid, Hugh Oge escaped from the Tower of London by sawing through his bars on 18 August 1644. However, he was recaptured 5 weeks later. He was convicted of treason and beheaded in London on 22 November 1644.
