Tyrone was married to Anglesey's daughter, and an attempt was made to implicate the latter, but it was too absurd to have any success. He was himself confined for some time in the Gatehouse, and the Lords declared themselves fully satisfied that there was and long had been 'a horrid and treasonable plot and conspiracy, contrived and carried on by those of the Popish religion in Ireland for massacring the English, and subverting the Protestant religion, and the ancient established government of that kingdom.' They desired the concurrence of the Commons, about which there was no difficulty, but Capel, Hampden, and Russell were determined to involve James, and it was added to the Lords' vote 'that the Duke of York's being a Papist, and the expectation of his coming to the Crown, hath given the greatest countenance and concurrence thereto as well as to the horrid Popish Plot in this kingdom of England.' According to the Maguire precedent Tyrone could be tried as a commoner in England, but the House preferred to resolve unanimously that he should be impeached of high treason. The charge came to nothing, for Parliament was dissolved a few days later. For the same reasons the proceedings against Thomas Sheridan were dropped, and he played an important part in Ireland during the next reign. He was a son of Dennis Sheridan, who befriended Bedell and others in 1641, his brother was Dean of Down and became a bishop next year. Being imprisoned by the House of Commons on vague and almost unintelligible charges, he sued out his Habeas Corpus, and when other judges shirked the task Baron Weston had the courage to grant it. The impeachment of Weston had also been voted for something he said at the Kingston Assizes. Sheridan told the House that he had defended the Protestant faith against the Jesuits and against friars of every order, that he had communicated yearly since he was seventeen, and that he had taken the oath of supremacy eleven times.[125] [Sidenote: Spies and false witnesses.] [Sidenote: Oliver Plunket accused.]
