Background
The statement in his brief of appointment that he was born in the ecclesiastical Province of Dublin is all that is known of his early life.
The statement in his brief of appointment that he was born in the ecclesiastical Province of Dublin is all that is known of his early life.
His surname was borne by persons of humble station at Calverstown, Company Kildare, which, coupled with his familiarity with the Eustaces of Baltinglas, may give colour to a surmise that he was a native of that district. His health, however, failed and he left the Society.
In 1574 he was again at Rome, and the See of Cork and Cloyne being vacant, he was appointed thereto, 5 November 1574, and was consecrated at Rome.
In May, 1575, he set out for Ireland with exceptional faculties for his own diocese and for those of Cashel, Dublin, and its suffragan sees in the absence of their respective prelates. A few days later he was himself released through the influence of a noble earl.
Thereafter he did not venture into his own diocese but as Commissary Apostolic he traversed the other districts assigned him, administering the sacraments and discharging in secret the other duties of his office. After four years he died in the Diocese of Ossory, 4 June 1579.
Anthony Bruodin states that he died in Dublin Castle after eighteen months of imprisonment and torture.
