In the Annals of the Four Masters c.1420 there appears entries which may be pertinent to the Adair history as appeared in the Adair of Bellgrove entry in Burkes. The entries for the Four Masters appear in the University College of Cork at:
M1419.14 O'Driscoll More, and the White Knight with his son died.
M1419.17 Thomas, son of Earl of Ormond (Justiciary of Ireland) went to assist King of England in war with France and died while on the expedition with the King of England. The greater numbers of those who went with them from Ireland died likewise either in England or France.
Other notes I had for MCormac was that in 1172 Dermond McCormac McCarthy was King of Desmond. In the Annals of the Four Masters M1381.4 Dermot MacCarthy, heir to the Lordship of Desmond was slain by O'Mahoney. In the Calander of State Papers for Ireland 1598-1599 (PRO 941.505 G786) the index showed Donogh McCormack - see Donnell McCarthy (More) son of Earl of Clancarty (or Clanricarty).I believe the Earls of Clanricarty share the same motto as one of the branches of the Adairs, that of "I Dare" and that a ship with Adair connections transported emigrants to America I think in the mid-1800s.
