O'Quins became Earls of Dunraven. A branch of the MacMahon family became Marquis de MacMahon d'Eguilly in the Kingdom of France, later raised to Dukes of Magenta under Emperor Napoleon III. The Clancy sept was the hereditary Brehons of Thomond and held a very powerful position when it came to the law in the kingdom. Even after the end of the Gaelic order, they continued to play a role, providing a High Sheriff of Clare in the form of Boetius Clancy. Famously participating in the Contention of the Bards in support of the honour of the tribe, the MacBrody sept were the principal poets and historians of the Dál gCais over the course of centuries. The O'Hickey and Neylon sept would serve as hereditary physicians to the Dalcassians of Thomond. After the Norman Butler dynasty took Ormond, the Dalcassian sept of O'Meara became their hereditary physicians, this line included Barry Edward O'Meara, who was with Emperor Napoleon I in exile at St. Helena. Chieftainship What became known as the Dál gCais stemmed from the Deisi Becc (Small Deisi) who controlled a narrow strip of land stretching from the Ballyhoura mountains to the Shannon and were divided into the Deisi Deiscirt (Southern Deisi, centred around Bruree) and Deisi Tuaiscirt (Northern Deisi, centred around Cahernarry) who shared a common ancestry. Their conquest of modern Clare probably occurred after the Battle of Carn Feradaig in 629AD where, under their king Díoma mac Rónáin, they defeated the King of Connacht Guaire Aidne mac Colmáin who was invading Munster. After this their Kings first appear in contemporary records. Andelait, son of Díoma is one of eight Munster kings listed as guarantors of the Cáin Adomnáin in 697. In 713 the Deisi Tuaiscirt killed the King of Cashel Cormac mac Ailello in battle at Carn Feradaig after he had invaded their territories. In 744 the annals note: "Destruction of Corco Mruad by the Déis" which indicates their power in Thomond was growing. In 765 the death of their king Torpaid is noted in the annals. From this point forwards the annals are silent on the Deisi Tuaiscirt until 934.<ref>Bart Jaski, The (legendary) rise of Dál Cais', in: Seán Duffy (ed.), Medieval Dublin XVI: proceedings of Clontarf 1014–2014: national conference marking the millennium of the Battle of Clontarf (Dublin, 2017). 15–61., https://www.academia.edu/38265900/Bart_Jaski_The_legendary_rise_of_D%C3%A1l_Cais_in_Se%C3%A1n_Duffy_ed._Medieval_Dublin_XVI_proceedings_of_Clontarf_1014_2014_national_conference_marking_the_millennium_of_the_Battle_of_Clontarf_Dublin_2017_._15_61?source=swp_share </ref> In 934 the annals report the death of Reabacán mac Mothla who is described
