Mary Hendrick of Douglas, whose appeal set the Governor of the Isle of Man against the Bishop and ended in the Bishop being fined.

She was the wife of John Hendrick, a licensed victualler in the town. On 29 May 1715 she was presented by the churchwardens for having committed adultery with Isaac Allgood of the same place, and on 5 June following she was legally convicted of it by the ecclesiastical court. The censure pronounced on her almost certainly included penance in all the churches. Allgood submitted to his, after some unpleasant delay. She did not: Keble, who compiled the Bishop's life from the diocesan registry, calls her altogether stubborn and rebellious, and records that people who were discontented with the Church's discipline had access to her and prevailed on her to become their instrument for setting the ecclesiastical laws aside.

Her appeal was the point. She appealed from the spiritual court to the Lord of the Isle, and the Governor allowed it. Bishop Wilson held that no such appeal existed. Governor Horne wrote from Castle Rushen on 7 September 1717 defending what he had done: the liberty given to Mary Hendrick to appeal to my Lord Derby, without the Bishop being present, had not been meant to prevent the Spiritual Court from being heard, and on considering the precedents and Lord Derby's own order he was satisfied that although the Lord had prohibited appeals of that kind from the Governor, the officers and the Deemsters, he had not debarred them from himself.

It ran for years and the Bishop lost. At Peeltown on 3 October 1718 the Governor called the Bishop before him to give his reasons why Lord Derby's order had not been complied with in the matter of Mary Hendrick's appeal, and the Bishop's answer was that there was no appeal in that case. J. Rowe, Clerk of the Rolls, signed the minute. A fine of ten pounds was awarded against the Bishop, and the records show it still being dealt with on 7 August 1719. The case was still running in 1721, by which time the Bishop had been to England and back, the Archdeacon Samuel Wattleworth had died on 20 December 1718 aged seventy-two and been buried in Peel Cathedral, and Lord Derby had kept that place vacant for months before inducting Robert Horrobin, Curate of Warrington, on 18 October 1719 while the Bishop was away.

It was not the first collision of the two jurisdictions. Governor Horne had already imprisoned a man who acted under the Bishop's authority, holding him until a book was restored, and that led on to the sharper disputes of which this appeal was the worst.
