Particulars of accounts from the Irish Exchequer from the reign of Henry III to that of Elizabeth I, the great bulk of them relating to the period from about 1275-1385. Because of the destruction of the Irish public record in 1922, they (with the related enrolled accounts) are easily the largest surviving source of information about Irish government for that period.
The ordinance of 1293 explains the survival in this series of a great many particulars of account arising from the accounts of the Irish Treasurer for the period down to 1446. The first group belong to Fulbourne's account (E 101/230/4, 8-31; E 101/231/3) and the subsequent proceedings against Nicholas de Clere resulted in the survival of a good many more subsidiary records (E 101/231/1-2, 4-26). Later Alexander de Bicknor, Treasurer fom 1308-1314, was accused of falsifying documents relating to his audit, which was held in 1323 after years of delay, so a full investigation was conducted, which resulted in the survival of more subsidiary documentation (E 101/235/5-24; E 101/236/1-10). The account was not finally enrolled until Bicknor was pardoned in 1344.
Types of particulars which have survived include copies of the Irish receipt and issue rolls, files of receipts and warrants (for example E 101/233/22-23), records resulting from complaints against sheriffs (for example E 101/235/4) or justiciars (such as E 101/232/11), extents of the lands of prominent individuals (such as E 101/233/6, 10), summaries of accounts, indentures, and even letters and petitions (E 101/246/9; E 101/247/17). There are some particulars of accounts of military and naval expenditure (for example E 101/246/11-12) but most items of that kind have been included in the section of E 101 devoted to Army, Navy and Ordnance.
At the beginning of the collection are also an account for the treasureship of Hugh de Taghmon for 1270 to 1272 (E 101/230/2), and two documents relating to the exchange of Ireland from the reign of Henry III (E 101/230/1,3). Other Irish Exchequer material from Henry's reign survives elsewhere. At the end are a slightly greater number of more miscellaneous Irish documents for the later fifteenth and the sixteenth century. For the period after the Irish Treasurer ceased to account at the English Exchequer there are a few miscellaneous Irish documents (E 101/248/15-23; E 101/540/19), by no means all of which related to financial matters. The latest date from the reign of Elizabeth I.
