Lease of part of the lands of Ballyduff from Edward Earl Digby to Loughlin Boland for one life, or twenty-one years from 25 March 1819, at the yearly rate of £7-14-2.
Including 'A map of part of the lands of Ballyduff in the Barony of Geashill and King's County. Part of the Estate of the Right Honourable Earl Digby. Surveyed by John Molloy 1819', hand coloured, scale 20 Perches to an Inch, with bordering land leased to Peter and Denis Flanagan, Dan Siney and John Carroll and Partners.

Legal notice served to James Hackett, Ballyduff on behalf of the agent for the Plaintiff, Lord Digby, regarding a decree pronounced by the King's County Court Judge.

Annual report and rental for year end June 1871, reporting a favourable financial situation on the estate and outlining the receipts and disbursements for the previous year. Describes the drainage of lands contiguous to the Clodiagh river and the formation of the Clodiagh Embankment, 490 statute perches in length. Also describes the completion of main drains at Derryweelan, Annagharvey and Killellery and notes improvements undertaken in Ballinagar and Ballyduff. In relation to buildings and repairs, he notes that there has been almost complete remodel of old houses and sundry other improvements 'that they might almost be classes as under new buildings.' Also reports that income from woods and plantations is reduced this year due to the 'improper and dishonest conduct of Forester Corbett'. Roskeen, Queen's County, is introduced to the accounts for the first time as an independent estate as Trench cites the differing rental schedules and differing counties as reasons for them not to be amalgamated in the rental.

In general, Trench is pleased not only with the improvements in the houses but also in the habits of the people, the tillage and agriculture and the green crops. On a more personal note, he expresses his 'deep grief' at the decision of his son, T. W. Trench to resign his post as Resident Agent on the Geashill estate. Describes him as 'beloved and respected by the tenantry and looked up to and appreciated by men of all creeds, politics or religions as a man of integrity, honour and intelligence.' Concludes by expressing this confidence that Lord Digby's nephew, Reginald Digby, will be an able successor to his son.
