Origins
The Donnellys (O’Donnellys) held the role of marshalls to the O'Neills of Tyrone. According to Gaelic Irish tradition, the Donnellys were part of the Cenél nEoghain making them kin of the O'Neills.
In their role as Marshalls to the O'Neills, they were responsible for fostering the children of 'The O'Neill'.
The Donnellys reached the height of their role during the time of
Shane O'Neill when Dean Terrence Danyell (Turlough O'Donnelly) of Armagh played a key role in communications between
Shane O'Neill and
Elizabeth I.
Ballydonnelly
The earliest mention of Ballydonnelly is the Annals of the Four Masters in 1531 when it is said Baile-Ui-Donnghaile was assaulted by Niall Oge, son of Art, son of Con O'Neill. He demolished the castle; and he made a prisoner of the son of O'Neill, who was foster-son of Donnelly, and carried him off, together with the horses and the other spoils of the town.
At the start of the Plantation of Ulster, Ballydonnelly was allocated as a 'Servitor' portion and as such was granted to
Sir Toby Caulfeild who had served in the Crown forces during the
Nine Years' War. The Donnellys were involved in the 1641 rebellion where Castle Caulfield, was badly damaged by fire.

Book of Ballymote and
Book of Lecan) have the line of descent of Donnghaile incorrectly stated as the great-grandson of
Domnall Ilchelgach, High King who died in 561 A.D.
^King Domhnall served as co-ruler of
Cenél nEoghain from about 896 A.D. with his paternal half brother
Niall Glundub until 911 A.D. when King Domhnall abdicated to “enter religious life” and subsequently died in 915 A.D.
