Hugh O'Donnell

The son of the Dean O'Gallagher, who was then usually styled Hugh, the
son of Calvagh O'Donnell.

1588

The Earl of Tyrone (Hugh, the son of Ferdorcha, son of Con Bacagh, son
of Con) mustered a very great army to march against O'Neill (Turlough
Luineach). The Earl never halted until he had crossed the Mourne and
the Derg, and ancamped at Carraic-liath. O'Donnell (Hugh, the son of
Manus) came to join the Earl, his son-in-law, with a number of his
forces but, however, he did not come with all of them. Turlough O'Neill
had on the other hand, a great army of unanimously combined forces to
oppose the Earl and O'Donnell. Niall Garv O'Donnell, Hugh the son of the
Dean O'Gallagher (who was then usually styled Hugh, the son of Calvagh
O'Donnell), with all the descendants of Calvagh, and their followers,
joined O'Neill with one accord on this occasion. These were then in
castlefinn. Some of his people were requesting of Hugh [O'Gallagher] to
make a nocturnal attack upon the Earl, who was then preying and
plundering the country between the rivers Finn and Mourne; but, through
pride and magnanimity, he did not deem this honourable, and said that
he would not attack an Earl in the darkness of the night, but that he
would give him a fierce battle in the broad light of day. This he
performed, for on the following day he attacked the Earl, and defeated
him. The Earl left behind great numbers of men, horses, and spoils, on
this occasion. This was on the Ist of May. AFM

Hugh the son of the Dean O'Gallagher (who was usually called Hugh, the
son of Calvagh O'Donnell), was killed by Ineenduv, the daughter of
James Mac Donnell, and wife of O'Donnell (Hugh, the son of Manus). It
was thus that she was enabled to effect this killing: Hugh had
constantly sided with the descendants of Calvagh O'Donnell, who were
all cojointly leagued with Turlough Luineach O'Neill, who was always at
war with O'Donnell and his son-in-law, the Earl O'Neill (Hugh, the son
of Ferdorcha). Moreover, her dearly beloved brother, Alexander, had
been slain by Hugh, son of the Dean, and besides these she had many
other causes of enmity towards him; and it was sickness of heart and
anguish of mind to her that revenge was not taken of him for his pride
and arrogance. She complained of her troubles and injuries to the
Scottish auxiliaries, who were constantly in her service and pay, and
who were in attendance on her in every place; and they promised that
they would be ready at her command, to wreak vengance upon their
enemies, whenever they should meet them. Hugh, one time, happened to be
coming up, in pride, vigour, and high spirits (without remembering the
spite or the enmity against him) towards the place where she was, at
Magh-gaibhlin. When he had come to the town, she addressed her faithful
people, ie the Scots; and begged and requested of them to fulfil their
promise. This was accordingly done for her, for they rushed to the
place where Hugh was, and proceeded to shoot at him with darts and
bullets, until they left him lifeless; and there were also slain along
with him the dearest to him of his faithful people. AFM
