Accounts of the receipt by Simon Theloal of the arrears of the issues of north Wales; receipts of issues and mises in Denbighshire, Flintshire, Montgomeryshire, Caernarvonshire, Anglesey and Merioneth in 1555-1556; account of money received by Simon Thelwall of the chamberlain of north Wales, and of disbursements made by him at the chamberlain's bidding; list of collectors of the second payment of a mise in Bromfield and Yale with their charges; fees and annuities paid by Simon [Thelwall] for the year ending Michaelmas 1555; and the account of Simon Thelwall, made to Sir John Salesbury, knight, of receipts for the year 1555-1556. Simon Thelwell, the writer of this manuscript, as well as MS 93 and section (a) of MS 86, was probably the son of Richard Thelwall of Plas y Ward. He was an MP for Denbighshire in 1553, 1563, and 1571, and high sheriff for the same county in 1572.
Among the loose papers in the volume are: (a) Receipt from Lanselot Alforde, porter of the Castle of Chirk, for £7.12.0 being two years' fee, paid by Simond Thelwall on behalf of Sir John Salesbury, knight, general receiver of north Wales, [1555]; (b) Receipt from John More for an annuity from the same source, 24 March 1555/6; (c) Receipt from Morgan Lloyd on behalf of the Earl of Penbrok, 1 April 1555; and (d) Inventory of the stuff remaining in the Exchequer at Caernarfon in Oct. 1555, after the death of Lewes Owen. This Lewes Owen, who was a baron of the Exchequer and vice-chamberlain of north Wales, was the victim of the vengeance of Gwylliad Cochion Mawddwy.
