The annals record an unusual number of bardic deaths in 1404. Donnchad Baccach Ó Maolconaire died, leaving the office of Irish: Ollamh vacant. His death was followed by Gilla Duivin Mac Curtin, Ollamh of Thomond in music, Carroll O'Daly, Ollav of Corcomroe; Donnell, the son of Donough O'Daly, who was usually called Irish: Bolg-an-Dana ... William O'Doran, Ollav of Leinster in judicature ... Teige, the son of boethius Mac Egan, intended ollav of Lower Connacht in law.
Flann Óc became Ollamh, but was dead himself before the year was out. His place was due to be taken by Tuathal, the son of Melaghlin O'Donnellan, intended ollav of Sil-Murray in poetry but Tuathal himself died before gaining the office.
