Letter sent by Robert Edward Dillon to his mother, Augusta Caroline Dillon (Lady Clonbrock) to congratulate her on her Golden Wedding, dated 17 July 1916.Augusta Caroline Dillon (née Crofton) was the wife of Luke Gerald Dillon (1834 - 1917), the 4th Baron of Clonbrock, Co. Galway and the daughter of Lord Crofton of Mote Park (Edward Henry Churchill Crofton, 3rd Baron), Co. Roscommon. Augusta was a skilled photographer and was responsible for creating much of the collection of 3,000 negatives and prints, now held by the National Photographic Archive of Ireland, which illustrates many aspects of life on the estate over a period of seventy years. She was also very active in promoting home industries at Clonbrock and in organizing voluntary work on behalf of local men serving with the British Army during the First World War, for which she was awarded an OBE in 1920. Robert Edward Dillon was the only son of Luke and Caroline Dillon and succeded his father as the 5th Baron of Clonbrock in 1917. Already in poor health, the 5th Baron, inherited a much reduced estate and died unmarried in 1926 when the title became extinct. Clonbrock House continued to be occupied by the 5th Baron’s unmarried sister, the Hon. Ethel Dillon, until the 1960s when the property passed to the 5th Baron’s grand-nephew, Sir Luke Dillon Mahon, who sold the remainder of the estate in 1976.
