*Christopher Bodkin, the son of a former mayor of Galway, was appointed by King Henry VIII with the pope’s approval, though no official papal sanction ever reached Ireland following the king’s break with Rome. Sometime later Bodkin took the Oath of Supremacy. In his stead, Rome proposed a Raphoe native named Arthur Ó Frighil. Following his special commissary of 1565–6, during the reign of Queen Mary, the Jesuit David Woulfe recommended that Bodkin remain in situ. Having spent some time with the latter in Tuam, he believed that Bodkin had taken the oath ‘more from fear than from conviction’.
** There was no papal appointee to Tuam during the tenure of Nehemiah Donelan.
