Photograph album created by Lt. Col. M. O'Carroll Fitz-Simon, M.C. , who began his military career in Prince of Wales' Leinster Regiment, which was headquartered at Birr. The photographs document a peace-keeping mission the Leinsters undertook in Silesia (now part of Poland) from their departure at Dover on 31 May 1921, through Germany and to their destination of Oppeln (Opole in Poland today). Following the disbandment of the regiment in June 1922, Fitz-Simon joined the King's Own Regiment, Lancaster and the remaining photographs in the album depict scenes from missions in India and Burma. There is also a small number of photographs of people and houses in the Birr area including Whigsborough House, and the burnt out remains of Birr Barracks (following its destruction in the Civil War in July 1922).

Correspondence and maps concerning Lisheen military rifle range, beside the 4th Earl’s property at Clonoghill, on the outskirts of Birr.

Annual report, accounts and rental for year ending June 1873, containing positive reports on the financial condition of the estate with only 'trifling arrears' of £32 and a general increase in overall rental income. Expenditure consisted of main drainage of lands at Roskeen, Queen's County; the reclamation of the bog at Killurin; thorough drainage at Bawnmore; construction of two new cottages in Geashill Village and a substantial range of offices for Mr Warren of Gorteen. Also comments on the scarcity of labour on the estate due to emigration to America, and that the 'Russian Village' (portable labourers' housing) has been moved to Cappyroe from Ballyknockan.

Regrets to say that relations with the tenantry are not entirely satisfactory. Tenants without a written contract were asked to sign one but the parish priest, using 'the extraordinary and mischievous power which an Irish priest possesses over an ignorant Roman Catholic tenantry', informed tenants that by signing they will exclude themselves from any benefit under the Land Act.

Describes the eviction of Mr. O'Flanagan, a large tenant on the estate, who had tried to establish 'tenant-right' through the courts but 'failed signally, as at the last moment before the claim came before the Chairman of the Quarter Sessions, Mr. O'Flanagan signed a paper admitting that he had no claim whatever to tenant-right in his holding.'
