| Which Mac Duinnshleibhe? There is a great deal of evidence to support the theory 
        that MacLea is derived from the name McDunsleibhe. Niall Campbell, later 10th Duke of Argyll thought that 
        “There is evidence of not only the 'd' but also the 's' dropping
          out by euphonistic elision, the name becoming Mconlave and McDunlave
        and Mcinlay, etc”.   He also thought that "it was possible" that
          this was the Dunsleve ancestor of the Lamonts, MacLachlans etc. This
           possibility has been picked up by others as probable or even factual! However, I believe that there are two
      possibilities as to our eponymic ancestor:  
         Dunshleibe Ua Anradhan  Dunshleibe Ua Eochadha  Dunshleibe Ua Anradhan The conventional view is that our eponymic ancestor was Dunsleve, the
          son of Aedh Alain who was the son of Aedh Anradhan (Anrothan), the
          O’Neill prince who married a Princess of Dalriada, inheriting
          her lands of Cowal and Knapdale. Anradan was descended from Niall of
          the Nine Hostages, High King of Ireland in the fifth century. I shall
      call this the Dunshleibe ua Anradhan possibility.
 The case for this theory is this: The argument for our descent from Anrothan is based on: 
         The assumption that our name is derived from MacDunshleibe That a Dunsleve existed in Cowal in the 1200s  That the name Molmore used in the 1544 Charter was often used
          by MacSweens.  I have always felt uncomfortable with this theory – and it should
        be remembered that Niall Campbell merely said that it was “quite
        possible” – he was clearly uncertain. 
 The case against this theory is this:
 
         Dunshleibe ua Anradhan was of the Cenél nGabráin.
            Given the antipathy between them and the Cenél Loairn, I cannot
            see how someone of the Cenél nGabráin could become
            the Coarb of St Moluag the patron saint of the Cenél Loairn.   I cannot identify our family in any of the genealogies – a
              strange omission if this theory were true.   Under Brehon law the succession should have gone to someone of
          the Fine Erluma, (Tribe of the Saint) or the Fine Grin (Tribe of the
          Land).
              Anrothan was not from either tribe so would not be eligible.  Anrothan would have O’Neill DNA – and although he
          married a Princess of the Royal House of Dalriada the Y chromosome
          is passed
            down the male line and his descendents would have the O’Neill
            DNA – not Dalriadic DNA.  Dunshleibe Ua Eochadha According to Byrne the Ulaid rigdamnai alone used the name Mac Duinnshleibhe
 
        “
          So for instance when after 1137 the Dal Fiatach kingship was confined
            to the descendants of Donn Sleibe Mac Eochada (slain in 1091), the rigdamnai
            set themselves apart from the rest of the family by using the name Mac
          Duinnshleibhe (Donleavy)." Byrne, page 128  It seems as though Ruaidhri Mac Duinnsleibhe was the last king of Ulidia
        dying at the end of the twelfth century . Rory, son of Dunsleve, is number
        54 on O'Hart's  roll of the kings of Ulidia and described as "the
        last king of Ulidia, and its fifty-fourth king since the advent of St.
        Patrick to Ireland."  In Irish Pedigrees – The Stem of the Dunlevy family, Princes of
      Ulidia, O'Hart says  
        “Tuirmach Teamrach, the 81st Monarch of Ireland
          had a son named Fiach Fearmara, who was ancestor of the Kings
          of Argyle and Dalriada, in Scotland: this Fiach was also the ancestor of MacDunshleibe          and O’Dunsleibhe, anglicised Dunlevy, Dunlief, Dunlop, Levingstone
        and Livingstone. … .According to Dr O’Donovan descendents
          of this family (Cu-Uladh the son the last MacDunshleibe King of Ulidia),
          soon after the English invasion of Ireland, passed into Scotland,
        where they changed their name.” Last references to Mac Duinnsleibhe in The Annals of Ulster  These entries record the end of the Mac Duinnsleibhe rule of Ulidia 
        U1165.5 Eochaidh Mac Duinnsleibhe [Ua Eochadha] was expelled from
        Ulidia. U1166.2 Cucuach Mac Gilla-espuic was killed by Donnsleibhe, grandson
          of Eochaidh [Ua Eochadha]. His sons were Donnsleibhe, Maghnus, Eochaidh
        and Aedh. U1166.8 Eochaidh Mac Duinnsleibhe [Ua Eochadha] was blinded by Muircertach
          Ua Lochlainn  in violation of the protection of
          the successor of Patrick and of the Staff of Jesus and of Donnchadh
        Ua Cerbaill, namely, the arch-king of Airgialla U1171.5 Great foraying force [was led] by Maghnus Mac Duinnsleibhe
                  [Ua Eochadha] with all Ulidia into Cuil-in-tuaisceirt, so that
              they plundered Cuil-rathain and other churches, until a small number
              of
                  the Cenel-Eogain under Conchobur Ua Cathain overtook them and
          gave battle and killed one and twenty men, both chiefs and sons of
          chiefs,
                  and a multitude of others along with them. And Maghnus himself
              was wounded. And moreover that Maghnus was killed shortly
              after in Dun
                  by Donnsleibhe, that is, by his own brother and by Gilla-Oenghusa
              Mac Gilla-espuic, namely, by the lawgiver of Monaigh, after great
          evils had been done by him,—namely, after leaving his own wedded
                  wife and after taking his wife from his fosterer, that is,
          from Cu-maighi
                  Ua Flainn and she [had been] the wife of his own brother at
          first, namely, of Aedh; after inflicting violence upon the wife of
          his
                  other brother also, that is, of Eochaidh; after profanation
          of bells and
                  croziers, clerics and churches. Donnsleibhe took the
        kingship in his stead. U1177.5 A hosting by John De Courcy and by the knights into Dal-Araidhe
          (and to Dun-da-lethlas), on which they killed Domnall, grandson of
        Cathusach [Mac Duinnsleibhe Ua Eochadha], king of Dál-Araidhe.  U1196.2 A hosting by Ruaidhri Mac Duinnsleibhe [Ua Eochadha] with
              the Foreigners and with the sons of the kings of Connacht to Cenel-Eogain
              and the Airthir. Howbeit, the Cenel-Eogain of Telach-oc and the Airthir
              came to the Plain of Ard-Macha and gave them battle and defeat was
              inflicted upon Mac Duinnsleibe and stark slaughter of his people took
        place there, namely, twelve sons of the kings of Connacht. U1200.4 A foray by Ruaidhri Mac Duinnsleibhe [Ua Eochadha] with some
              of the Foreigners of Meath, so that they pillaged the Monastery
          of Paul and Peter [in Armagh] until they left not therein but one cow.  Byrne says that  Ruaidhri died in 1201 The case for this theory is this: The argument for our descent from Donn Sleibe Mac Eochada  is based
      on: 
         The assumption that our name is derived from MacDunshleibe That since 1137 the name
        Mac Duinnshleibhe was reserved for the  the rigdamnai
        of UlaidThat the Mac Duinnshleibhe entries in the Annals of Ulster suddenly
          stop in the early 1200sThe fact Cudulig was Abbot of Lismore in 1150, but that he appeared
          to be an interregnum as his descendents were appanaged in Morvern – becoming
        the MacleansThis suggests that a new line of abbots (or an older line resumed)
          in the early 1200sThat the office of Abbot was held in very high regard and that the
            Coarb of St Moluag was a very high office – more than suitable
        for an exiled prince. That the Mac Duinnshleibhe shared a common ancestor with
            Kings of  Dalriada - Fiach
            Fearmara.That the Mac Duinnshleibhe were therefore of the
          Fine Grin (Tribe of the Land) and so would  be eligible.The Ui Echach Coba and the Dál nAraide descend
        from Fiacha Araide, ancestor of Moluag That Cathusach Mac Duinnsleibhe Ua Eochadha was described as king
          of Dál-Araidhe
          . That the Mac Duinnshleibhe were therefore of the Fine Erluma (Tribe
        of the Saint) and so would be eligible.Therefore the Mac Duinnshleibhe were  of both the Fine Erluma
            and the Fine Grin so VERY eligible.Most Highland families adopted their surnames after
            an eponymous ancestor who lived c.1150-1350. We are recorded as using
        this name as far back as the 1500s. Conjecture There is an intriguing reference in U1166.2 -"Donnsleibhe, grandson
        of Eochaidh [Ua Eochadha]. His sons were Donnsleibhe, Maghnus, Eochaidh
      and Aedh". The conventional view is that  Dunsleve,was the
        son of Aedh Alain who was the son of Aedh Anradhan (Anrothan). Perhaps
      this is the case.  But It may be that our line is Dunsleve, the
      son of Aedh MacDunshleibe  Ua Eochadha.
