Kitty died, aged 52, of a cerebral hemorrhage on 24 July 1945, and her grave is close to that of Collins. Felix Cronin died suddenly on 22 October 1961 while playing golf at Woodbrook Golf Club and is also buried in Glasnevin. Bright’s disease Several sources, for example, a 1996 piece from the Irish Times entitled ‘Life after Mick’, state that Kitty Kiernan plus several of her siblings died of Bright's disease – what one would class today as chronic nephritis. Her sisters Maud (2 October 1895–28 October 1940) who married Gearóid O'Sullivan on 18 October 1922 and Helena Josephine (22 September 1894–28 May 1940) who married solicitor Paul McGovern on 5 October 1921 both have chronic nephritis registered as their cause of death. While the cause of death for Kitty is registered as a cerebral hemorrhage, the suggestion is that she suffered from ill-health for several years before her death. Her only brother, Laurence Dawson Kiernan (22 Jan 1892–22 December 1948), of the Greville Arms Hotel, died of cirrhosis of the liver. Her twin sisters, Lizzie and Rose, both died in 1907 of tuberculosis–one in Granard and one in Switzerland. Her sister, Christina Margaret (b. 9 December 1890), married Thomas Magee on 22 June 1921 in Dublin. Kitty was a witness. Christina died on 3 February 1953 in Castlebar. Correspondence Kitty Kiernan and Michael Collins kept up a lengthy correspondence and while Collins was in London during the Treaty negotiations, he wrote to her every day. These letters are the subject of a book written by Leon O'Broin entitled "In Great Haste". Kitty's worst fears were realized when Collins was killed in action at the age of 31 near Béal na Bláth, County Cork, on 22 August 1922. In 2000, some of the 300 letters sent by Kiernan and Collins to each other went on permanent display at the Cork Public Museum. These letters give a great insight into Kitty's attitude to life and into the political events of this time. Former Fine Gael minister Peter Barry donated his collection of historic letters to the Lord Mayor of Cork, on behalf of the municipal museum. The collection, purchased from the Cronin family in 1995, was conserved at the Delmas bindery at Marsh's Library in Dublin: the letters were also catalogued and then returned to the Cork Public Museum. The Peter Barry collection contains letters from Harry Boland, a friend
