Sodor and Man (1)

This made a total of forty, to which the archdeacon and clergy of Man were later added, giving forty-two. Before 1553, each archdeacon also sent his official principal, though this practice seems to have ceased after that time. In addition to these, however, there were twenty-six826 representatives of various peculiar jurisdictions who were not originally provided for (or represented) but who managed to establish their rights over the course of time. These were:

The clergy of the peculiar jurisdiction of the dean and chapter of York (2)

The collegiate church of Southwell (1)

The clergy of the peculiar jurisdiction of Southwell (2)

The collegiate church of Ripon (1)

The keeper (custos) of Howden and Howdenshire (1)

The keeper of Allerton and Allertonshire, belonging to the bishop of Durham (1)

The keeper of Allerton and Allertonshire, belonging to the dean and chapter of Durham (1)

The chapter of Howden (1)

The clergy of Howden and Howdenshire (2)

The clergy of Allerton and Allertonshire, belonging to the bishop of Durham (2)

The clergy of Allerton and Allertonshire, belonging to the dean and chapter of Durham (2)

The provost of Beverley (1)

The chapter of Beverley (1)

The official of Beverley (1)

The clergy of Beverley (2)

The dean of Chester-le-Street (1)

The dean of Langchester (1)

The dean of Darlington (1)

The dean of Kirkoswald (1)

The provost of Graystoke (1)

In practice, this number was reduced to fifteen after 1547, when the proctor for the chapter of Howden, the deans of the collegiate churches and the representatives from Beverley no longer appeared. It was also the case that Allerton and Allertonshire had a single representation until 1640, and occasionally after that, which further reduced the numbers.
