In the year 1463, _Matthew_ or _Mahoun O’Griffa_ was appointed by Pope Pius II., Bishop of Killaloe. He had hitherto held the canonry and prebend of Teampul-monin, in the diocese of Limerick, the annual revenue of which amounted to twenty marks, and the _Monumenta Vaticana_ preserve an interesting fragment, which records the appointment of Donald Magillapadrig as his successor in that dignity: “Confertur ipsi canonicatus et prebenda de Tampolmonin in Ecclesia Limericensi quorum fructus viginti marcharum sterlingorum non excedunt et quos Mattheus electus Laonensis tempore suae promotionis obtinebat” (17 Decemb., 1463; pag. 455). Dr. O’Griffa died in 1482, and was succeeded the same year by Terence O’Brien, who ruled the see for forty-three years, and, as Ware informs us, “was a prelate of great account among his people for his liberality and hospitality”. Richard Hogan, a Franciscan, was chosen his successor in 1525, and after an episcopate of fourteen years, was translated to Clonmacnoise by Pope Paul III., on 16th June, 1539. He, however, enjoyed this new dignity only for a little while, as, a few days after his translation, he was summoned to his eternal reward. It is remarkable that the episcopate of his successor in the see of Killaloe was equally short; for, _Tirlogh_, in Latin _Theodoricus O’Brien_, appointed its bishop in June, 1539, died before December the same year. Both sees being thus vacant at the same time, _Dr. Florence O’Gerawan_, _i.e._ Kirwan, was appointed bishop of Clonmacnoise and Killaloe on 15th December, 1539, the union of these sees being at the same time limited to the lifetime of this bishop. The following is the consistorial entry:— “Anno 1539, 15 Decembris: Sua Sanctitas providit Ecclesiis Claonensi et Laonensi in Hibernia vacantibus per obitum Richardi et Theodorici de persona fratris Florentii Igernam (sic) ord. Fratrum Min. cum dispensatione ex defectu natalium et unione duarum Ecclesiarum ad vitam dicti Florentii”. We have already had occasion to speak of this bishop when treating of the see of Clonmacnoise (_Record_, part 1., pag. 157); his episcopate was marked by many signal events, and his zeal in the defence of the Catholic faith merited for him the hatred of the enemies of our holy Church. He died in 1554, and had for his successor Terence O’Brien, who received his appointment in the beginning of Queen Mary’s reign, and continued to administer the see till his death, which is registered by the _Four Masters_ in 1569. _Malachy O’Molony_ was next proclaimed in consistory on 10th January, 1571. He suffered much from the agents of the Protestant establishment: “Plurima ab haereticis mala et nonnunquam carceris acrumnas passus est” (Mooney, _MS. Hist. Francis._); and on 22nd of August, 1576, his translation to Kilmacduagh was solemnly promulgated in the Roman court.
