He later became spiritual director to the exiled Earl and Catherine O'Neill, Countess of Tyrone, with both of whom he traveled to Rome.
Under interrogation, O'Loughran admitted that he had given sacraments to exiled members of the Gaelic nobility of Ireland, and that he had assisted the Irish bishop, Blessed Conor O'Devany.
Fr O'Loughran's closeness to The O'Neill Mór appears to have been the reason behind the government's decision to single him out.
The bishop asked to die last so that he could provide Father O'Loughran moral support in his moments before death, but the request was refused.
O'Loughran and O'Devany were beatified by Pope John Paul II in September 1992 and 15 other Irish Catholic Martyrs.
