 Hostility to the Síl nÁedo Sláine was evidenced by the expulsion of Fogartach mac Néill (died 724) from the kingship of Brega in 714 who went into exile in Britain.This appears to be the work of Fergalin in conjunction with Murchad Midi (died 715) the King of Uisnech of Clann Cholmáin and Murchad may have been Fergal's deputy ruler in the south.Fogartach's uncle Conall Grant (died 718) killed Murchad the following year and Fogartach returned in 716.
