Letters sent to Henry Trench between 1853 and 1879.

The majority of the letters in this sub-series concern business matters. However personal issues such as Henry's concern over an unsuitable engagement are also covered.
Henry was also the most involved of the Trench family in Offaly and Tipperary communities. As a result of this local affairs are covered in some of these letters.

‘W’ and ‘’Y’ - principally Edward Walsh (town clerk of Birr, who writes about all manner of local government matters), Harold J. Wiley & Co., insurance brokers of Dublin (who write about Birr Castle insurance), Mrs F. White Spunner of Milltown Park, Shinrone, King’s County (whose estate Garvey managed [although, apart from these letters, no other record of this agency survives in the archive at Birr Castle]).

Includes minor letters from Captain P. Wall, Castle Barracks, Birr (1922-1923).
